Calycogonium bissei from eastern Cuba is described as a species new to science and illustrated. C. bissei is closely
related to C. revolutum, from which it can be distinguished by its elliptic to lanceolate leaves with two pairs of sec-
ondary veins, inflorescences of 3-flowered dichasia or 4 5-flowered fasciculate cymes and non-unguiculate petals.

Introduction
Ongoing phylogenetic studies in several genera and spe-
cies groups of Miconieae (Melastomataceae) have dem-
onstrated that most genera in this tribe are not mono-
phyletic. However, there are several well supported clades
that can also be diagnosed by unique morphological
characters (Bécquer-Granados & al. 2008; Michelangeli
& al. 2004, 2008).
During a morphological study of species groups
belonging to those clades and currently assigned to
the genera Calycogonium DC., Miconia Ruiz & Pavón
and Pachyanthus A. Rich., I came across an enigmatic
species collected in La Melba (municipality of Moa,
Province of Holguín, eastern Cuba) that had been identi-
fied as P. oleifolius Griseb., an eastern Cuban endemic
only known from the type gathering made by Charles
Wright in 1861. Comparison with Wright’s type mate-
rial showed that the specimens from La Melba are not
P. oleifolius but represent a still undescribed species,
morphologically similar and likely closely related to C.
revolutum Alain.
Calycogonium revolutum forms a small clade with
Pachyanthus reticulatus Britton & P. Wilson and both are
related to other Calycogonium species, viz. C. plicatum
Griseb., C. floribundum Borhidi and C. grisebachii Tri-
ana (Bécquer-Granados & al. 2008; Michelangeli & al.
2008). These species share the synapomorphy of abaxi-
ally densely stellate-pubescent leaves and their inflores-
cence is sometimes reduced to a single flower (Judd &
Skean 1991). C. revolutum and P. reticulatus also share
the feature of locules extending into the free distal por-
tion of the ovary with the new species.
Considering the difficulty of clarifying the generic
limits within Miconieae and in view of the impossibility
of solving the problem in the near future, the new species
is here included in Calycogonium, in conformity with the
traditional taxonomic position of the species group to
which it is related.

Etymology. The epithet it is dedicated to Prof. Dr Jo-
hannes Bisse, eminent German botanist, founder of the
National Botanical Garden of Havana and Professor of
Botany at the Faculty of Biology at Havana University,
who dedicated his life to the education of several genera-
tions of Cuban botanists.
Delimitation. Calycogonium bissei can be distin-
guished from C. revolutum by its elliptic to lanceolate
leaves measuring 2.5 6.2 × 1.1 2.7 cm (versus linear-
lanceolate and 2 4 × 0.6 1 cm in C. revolutum) with two
pairs of secondary veins, the second pair suprabasal, aris-
ing 1 5 mm above the base, impressed above and promi-
nent below (versus with a single pair of secondary veins
arising c. 1 mm above the base, inconspicuous on both
faces in C. revolutum), usually 3-flowered dichasia or
4 5-flowered fasciculate cymes (versus usually solitary
flowers in C. revolutum), not unguiculate, obovate petals
measuring 7 8 × c. 4 mm, with a fringe of scattered stel-
late hairs along the entire margin (versus conspicuously
unguiculate, glabrous petals of 1.7 1.8 × c. 1 cm in C.
revolutum).
Phenology. Not much is known about the exact flow-
ering period. Plants with buds, flowers and very young
fruits have been collected in May and June; material with
immature fruits has been collected also in December.
Distribution and habitat. Calycogonium bissei is
endemic to eastern Cuba (provinces of Holguín and
Guantánamo), where it occurs in ± thorny xerophytic
scrub and semidry montane rainforest on serpentine, at
altitudes between 300 and 800 m. Associated species in-
clude C. grisebachii Triana, Henriettea acunae (Alain)

A putative morphological synapomorphy of this clade found in almost all the species except for M. susannae is the presence of partially inferior ovaries with the locules extended into the free portion of the ovary (Bécquer Granados 2010;Bécquer 2011;Bécquer et al. 2014). Miconia susannae is a narrow endemic to Cuchillas del Toa, Eastern Cuba, only known from its type collection and one recent, sterile collection. ...
Chapter
Miconieae are the largest tribe in the family Melastomataceae with ca. 1900 described species. The Greater and Lesser Antilles harbor an impressive number of species from the Miconieae, which occur throughout the islands. Four major clades of Miconia are represented in the Antilles, the Caribbean, Chaenopleura, Mecranium, and Sagraea clades, corresponding to five in situ radiations. The Caribbean clade consists of ca. 160 spp., the Chaenopleura clade (= Miconia sect. Chaenopleura) of ca. 55 spp., Mecranium clade (= Miconia sect. Sagraeoides) of ca. 25 spp., and the Sagraea clade (= Miconia sect. Sagraea) of ca. 45 endemic spp. and is represented by two separate radiations in the Antilles. Likewise, numerous widespread continental species (ca. 45) from disparate subclades across Miconieae occur throughout the islands (presumably originating from many long-distance dispersal events), further increasing the Melastome diversity there. Each of these major clades is briefly characterized, and the evolutionary/phylogenetic patterns within each are discussed. Based on a phylogenetic framework, we discuss the patterns of diversification among the islands, as well as some of the biogeographic patterns of these fascinating radiations within the islands. We incorporate known data regarding ecological pressures and morphological evolution that likely have aided the diversification of this clade principally throughout the mountainous areas of the islands. Three new combinations are made in Miconia for Mecranium integrifolium, Miconia neibensis (Skean) Skean, Judd & Majure, comb. nov., Miconia neibensissubsp.alainii Skean, comb. nov., andMiconia neibensissubsp.integrifolia Skean, comb. nov.

Premise of research. The Sandpaper clade comprises a group of taxa endemic to the Greater Antilles and forms a subgroup of a larger Caribbean assemblage of Miconieae. Numerous species within this monophyletic group share striking morphological characters and thus traditionally have been considered close relatives. Recent phylogenetic work has shown that not all of these species are each other's closest relatives, and they actually form three distinct clades: the Lima, Paralima, and Pseudolima clades. We reconstructed a phylogeny of these poorly known species to test patterns of morphological evolution and the biogeographic history of the clade. Methodology. We reconstructed a phylogeny of the Sandpaper clade using two plastid intergenic spacers (accD-psaI, psbK-psbL) and two nuclear ribosomal spacers (ITS, ETS) and then sequenced three more plastid spacers for the Lima clade (rpl32-trnL, trnV-ndhC, trnH-psbA) to provide better resolution among those species. The biogeographic history and the evolution of morphological traits were tested using maximum parsimony based on 12 mountain ranges in the Greater Antilles and 48 morphological characters, respectively. Pivotal results. The Sandpaper clade most likely originated in eastern Cuba, with subsequent dispersals to other parts of the island, as well as to Jamaica, Hispaniola, and Puerto Rico. In general, morphological characters shared by the Lima, Paralima, and Pseudolima clades evolved independently. All subclades of the Sandpaper clade can be recognized by suites of characters; however, unique synapomorphies for clades are rare. Conclusions. Eastern Cuba formed the starting point for the diversification of the Sandpaper clade, likely as a result of the diverse topography and associated ecological diversity (e.g., serpentine soils). This clade represents only a moderate-sized radiation of the Caribbean clade; however, the convergent nature of character evolution and the lack of unique synapomorphies for subclades underscore the lability of morphological characters in this group and the difficulty in recognizing these clades from a purely morphological standpoint.

In order to assess seed morphology 47 species of Miconieae (Melastomataceae) from the Antilles were studied. The majority of these species belong to Calycogonium, a complex genus that has been shown to be polyphyletic, but for which we lack for many species any recent and suitable material for molecular systematics studies. A better understanding of homoplastic versus synapomorphic seed characters may therefore be helpful to illuminate the affinities of such species. Some taxa from Clidemia, Miconia, Ossaea, Pachyanthus and Tetrazygia were also sampled due to their morphological similarities with some species of Calycogonium. Variable seed characters include overall shape and size, raphe shape and size, and testa sculpturing. Based on these characters we grouped the species in five seed types, and an additional three species were found to have distinctive seeds that were not grouped with any other species. Species with identical seed types often belong to more than one genus as currently classified. There are five groups of species within Calycogonium characterized by similar seed morphology but none of the respective seed types is exclusive to the genus. Some of these seed types correlate well with previously proposed subgeneric groups of Calycogonium based on flower morphology and presences and type of leaf domatia. While the occurrence of some seed characters and states matches species groups in Calycogonium also found with molecular phylogenetic analyses, seed morphology generally indicates relationships of Calycogonium and allied taxa of the Caribbean clade that are not completely reflected by the current generic classification. The study provides a matrix for seed characters of the included species that will serve further phylogenetic reconstruction and analyses of character evolution.

Calycogonium pseudofloribundum of the Melastomataceae tribe Miconieae, from eastern Cuba, a species new to science, is described and illustrated. C. pseudofloribundum is closely related to C. floribundum, with which it has been confused for a long time. It can be distinguished from the latter species by leaf features (the ovate to lanceolate leaves have an acute to apiculate apex, the blade is flat to slightly revolute, the margin usually obscurely to minutely dentate towards the apex, the adaxial surface is flat and usually opaque to whitish in dry material by presence of wax layers; they have two, rarely one, pair of secondary veins, the second pair originating 2-9 mm above the base), the external calyx teeth being 5-6 mm long, and the petals being white, obtuse to acute, 4-5 × 2-2.5 mm. An amended description and an illustration for C. floribundum is also provided.

A new species of Miconia belonging to a clade diagnosed by strongly four-lobed ovaries/hypanthia and elongated calyx teeth flattened parallel to the floral radii, i.e., the Calycogonium hispidulum complex, endemic to the Sierra Maestra of eastern Cuba, is described, illustrated, and compared with related Cuban species. The discovery of Miconia becqueri brings to 15 the number of recognized species of this complex, seven of which occur in Cuba (if Clidemia barbeyana is conspecific with C. wrightii).

Miconieae is the most diverse tribe of Melastomataceae, with 30 genera and over 2200 species. The tribe is characterized by fleshy fruits and partially to totally inferior ovaries. To test monophyly of the tribe and assess phylogenetic relationships within it, sequence data from nrITS were gathered and analyzed for 110 taxa in Miconieae and 32 putative outgroups. The tribe Miconieae is not resolved as monophyletic, but rather composed of two distinct clades: one composed of the cauliflorous genera Henriettea, Henriettella, Loreya and Bellucia, and a second clade with all other taxa in Miconieae, sister to a polytomy that includes representatives from tribes Merianieae and Blakeeae. Terminal inflorescences are optimized as basal within Miconieae, with lateral inflorescences evolving in at least four different instances. Cauliflory does not appear to be derived from truly axillary inflorescences; instead it seems to have evolved independently. The terminal-flowered genera Tococa, Conostegia, Tetrazygia, Anaectocalyx, Charianthus, Calycogonium, and Leandra pro parte seem to be derived from within the large genus Miconia, as is Clidemia, a genus with both axillary inflorescences and terminal inflorescences that are deflexed to a lateral position by an axillary branch. Maieta and Necranium, both with axillary inflorescences, are resolved as derived from within Clidemia.

Pachyanthus (Melastomataceae: Miconieae) is traditionally circumscribed as a group of 20 species of Caribbean shrubs, mostly local Cuban endemics. However, the exact number of species is unknown because generic delimitations are still unclear for most genera of Miconieae. To test the monophyly of Pachyanthus, we produced a molecular phylogeny using nrITS and plastid trnS-G sequence data for 38 taxa of Miconieae in the genera Pachyanthus, Calycogonium, Tetrazygia, and Miconia. A species of Graffenrieda, a member of the sister group, Merianieae, was used as an outgroup. In the single-gene and combined analyses Pachyanthus is never recovered as a monophyletic group in any of its traditional circumscriptions. However, it is possible to distinguish a clade, Pachyanthus s.s., which is characterized by ovate to obovate petals that are conspicuously unguiculate; calyx lobes connate before anthesis, that separate into sepal-like segments; straight, ovate to oblong, yellow anthers without connective appendages or, if present, then inconspicuous, anthers dehiscing by small apical pores, and fruits with numerous seeds, 1-2 mm long, obpyramidal, with a smooth testa. The remaining species traditionally included in Pachyanthus do not have any of these features. They do not form a single monophyletic group, but instead are scattered across several clades, which also contain species of Calycogonium, Miconia, and Tetrazygia. Additional detailed molecular and morphological studies are needed in the Miconieae to ascertain whether these clades should be treated as new genera or recircumscribed as part of currently recognized genera in the Caribbean region, such as Calycogonium and Tetrazygia.

In the Caribbean region, the Melastomataceae are represented by about 450 species (from 28 genera), close to 400 of them endemic. The majority of these endemic species (approximately 330) belong to the tribe Miconieae, a monophyletic group characterized by flowers with inferior or partly inferior ovaries that develop into baccate fruits, stamens with no or only poorly developed connective appendages, and the absence of megastyloids and imbricate bracts at the base of the flowers. A phylogenetic analysis of 460 accessions from 450 species of the tribe Miconieae, including 139 present in the Antilles (103 of these endemic), was performed based on nuclear (nrITS) and plastid (ndhF) DNA sequence data. This analysis shows that most of the Caribbean endemics are the product of five radiation events: (1) a clade containing the Caribbean endemic (or near-endemic) genera Pachyanthus, Calycogonium, Tetrazygia and Charianthus, as well as a few representatives of Miconia and Leandra. (2) The genus Mecranium. (3) The Caribbean species of Miconia section Chaenopleura (which are probably not the sister group of Andean Chaenopleura). (4) The Greater Antillean species of Clidemia and Ossaea (including Sagraea). (5) The Lesser Antillean representatives of Clidemia. Caribbean endemics that are more closely related to mainland species, rather than other Caribbean species are rare, and these often are segregates of widespread continental species. Because of a lack of resolution at the base of several clades, it is currently not possible to determine which mainland groups are the closest relatives of these Caribbean endemics, thus preventing us from establishing unequivocally the geographical origins of these species.

Rapid diversification and high levels of homoplasy have combined in Miconia and relatives to make generic delimitation extremely difficult. Historically, the morphologically divergent members of particular clades have been recognized as segregate genera, leaving a diverse and paraphyletic remnant within Miconia. Here the monophyly and cladistic relationships of the commonly recognized terminal-flowered genera of Miconieae are investigated, and a provisional generic classification is constructed. Recognized genera include: Anaectocalyx, Calycogonium (including Mommsenia, and a few species of Clidemia and Ossaea), Clidemia (including Heterotrichum, Miconia sect. Octomeris p.p., Myrmidone, and a few species of Tococa), Conostegia, Leandra (including Platycentrum, Pleiochiton, and several species of Ossaea and Clidemia), Pachyanthus (including Miconia lundelliana), Tetrazygia (including Tetrazygiopsis and several species of Miconia), Tococa (including Microphysca), and Miconia (including Charianthus, Ossaea sect. Octopleura, Icaria, and a few species of Clidemia). It is hypothesized that all of the above, except Miconia, represent monophyletic groups. Most species of Miconia likely are members of a single clade, but a few primitive members of this genus may belong to isolated clades, or clades whose derived species are placed in other genera, making Miconia paraphyletic. It may eventually be possible to realign and/or segregate some of these basal lineages within Miconia. However, at this time high homoplasy levels and lack of clear morphological gaps between basal members of the various lineages combine to make phylogenetic decisions very difficult. Although not fully phylogenetic, the proposed generic classification is considered an improvement of the present system, basically that of Cogniaux, in that the artificial and polyphyletic genera Clidemia sensu lato, Calycogonium sensu lato, Ossaea, and Charianthus are abandoned. The traditional maintenance of these genera has resulted from selected weighting of variable features such as petal shape, apex, and color, along with the confusion of terminal with axillary inflorescences. Nomenclatural changes have been avoided with the exception of Calycogoniumapleurum, C. lomensis, C. reticulatum, C. tetragonolobum, Clidemia angustilamina, Leandra alloeotricha, L. glomerata, L. hirsuta, L. inaequidens, L. krugiana, L. krugii, L. lima, L._limoides, L. pratensis, Miconia coccinea, M. corymbosa, M. leblondii, M. purpureus, M. fadyenii, M. neomicrantha, and Pachyanthus lundellianus.
