... Hence, taxonomic study of Govenia ideally requires examination of live specimens to achieve a familiarity with the distinguishing characters of the species; then, identification of herbarium specimens may be attempted using a combination of morphological characteristics and, in some instances, distributional/ecological data. Regrettably, purportedly new species continue to be described solely based on ill-defined outlines of boiled labella from herbarium specimens (Szlachetko & Kolanowska 2014), which adds to taxonomic confusion. ...
Natural history of the often-misunderstood Govenia utriculata (Orchidaceae): discovery of a Mexican population upsets West Indies endemism
Article
  • Feb 2021
Govenia utriculata (Sw.) Lindl. has been pervasively confused in herbaria and the literature, despite showing both vegetative and florally distinctive attributes. Here we document for the first time its presence in Mexico, provide a description, a detailed drawing and color photographs from live flowering plants, and compare it with its congeners. All verifiable records indicate that G. utriculata is restricted to the Bahamas, the Greater Antilles, and now also Mexico; literature reports from elsewhere were based on misidentifications. Govenia utriculata is distinguished by the large inflated sheath enclosing the leaf petioles, which in living condition is circular in cross section and partially filled with rainwater; such ample sheath is evident in herbarium specimens and shared only by Mexican endemic G. lagenophora Lindl. Florally, G. utriculata is recognized by its small, white flowers, narrowly elliptic, falcate, acute petals with transverse magenta bars above the middle of their inner surface, and narrowly ovate, acuminate labellum with longitudinal keels only below the middle. The single known Mexican population of G. utriculata occurs in a tropical deciduous forest nature reserve (Sierra Montenegro) in the state of Morelos, and thus is under nominal protection; moderate disturbance from trampling and nearby agriculture and cattle ranching was observed in the location but the population seems to be tolerant to such disturbance and all reproductive individuals were found in partially open areas and forest edges. All Mexican plants examined had auto-pollinating flowers; auto-pollination resulted from germination of the pollen on the rostellum briefly before anthesis, apparently precluding cross-pollination as the pollinia are stuck to the rostellum when the flowers open.

... during the last few decades, several new species of Govenia from Mexico, Central-and South america have been proposed (e.g. Greenwood 1993;Salazar & Greenwood 1993;Greenwood & Soto arenas 2003;dressler 2002;García-Cruz & Sosa 2006;Szlachetko & Kolanowska 2014). recent exploration of cloud forest remnants in central veracruz, Mexico led to the discovery of an additional, undescribed species of Govenia, which is described and illustrated here. ...
Govenia polychroma, a new species of Orchidaceae from Veracruz, Mexico
Article
Full-text available
  • Mar 2018
Govenia polychroma, a new orchid species from central veracruz, Mexico is described and illustrated. It is similar to G. matudae, G. praecox and G. rubellilabia in the relatively small flowers, two leaves and globose corms, but differs from all previously described species in the purplish-magenta petals with yellow apices and the strongly conduplicate, narrowly channeled column foot. due to its small geographical range (less than 1 km 2) and the small number of both populations (two) and individuals (14), the new species is considered as endangered.

Pterichis aragogiana (Orchidaceae), a New Species from Ecuador
Article
  • Feb 2019
Pterichis aragogiana Kolan. & Szlach. sp. nova (Orchidaceae) is described and illustrated based on Ecuadorian material. It can be distinguished from other species of sect. Pterichis by the narrow, almost linear petals, sepals with almost caudate apical portions, prominent lip middle lobe which is longer than the basal part of the lip, and by the apical part of the lip middle lobe which is non-fleshy and lacks any distinctive glands. So far two populations of P. aragogiana are known, both from páramo in the Andean region.

The order Orchidales is divided into three families: Apostasiaceae, Cypripediaceae and Orchidaceae, with the last containing eight subfamilies. Appropriate new combinations at species level toalling 315 are proposed. The system proposed here is not based solely on similarities and differences in the generative structures. To avoid a too unilateral approach to the subject the author also used classical morphological data when analysing evolutionary connections between orchid groups (leaf venation, position of the inflorescence, etc.), collected during studies of herbarium materials and available in floristic works already published. -from Author

Phylogenetic relationships and character evolution in Govenia (Orchidaceae)
Article
Full-text available
  • Mar 2005
  • CAN J BOT
Govenia Lindl. (Orchidaceae) is a neotropical terrestrial deciduous genus of approximately 28 species of the higher Epidendroids. To determine if Govenia is monophyletic and what are the relationships among its species, a phylogenetic analysis based on a detailed morphological study was conducted. Furthermore, the evolution of eight vegetative and floral characters is explored and explained in relation to pollination syndrome. Three most parsimonious trees were retrieved from heuristic searches. Govenia is corroborated as monophyletic with six recognized groups: three monotypic groups (G. ciliilabia, G. powellii, and G. boliviensis) and three major clades (Purpusii, Capitata, and Superba groups). The Purpusii group is characterized by a well-developed rhizome, a solitary leaf, and 3–12 white flowers. The Capitata group is characterized by the lack of a rhizome, two leaves, and 10–30 white flowers. The Superba group is characterized by the lack of a rhizome, two leaves, and numerous yellow flowers. Two trends were identified in Govenia. The first trend is represented by plants with a rhizome and reduced leaf and flower numbers that occur in taxa from the Purpusii group. The second trend has been to increase inflorescence length and the number of flowers, to change flower colour from white to yellow with an ascending position of the column, and is represented in taxa from the Superba group. The evolution of floral characters leads to the hypothesis that there was a shift in pollinator from small bumblebees to larger bumblebees.

A Phylogenetic Analysis of the Orchidaceae: Evidence from rbcL Nucleotide Sequences
Article
Full-text available
  • Feb 1999
Cladistic parsimony analyses of rbcL nucleotide sequence data from 171 taxa representing nearly all tribes and subtribes of Orchidaceae are presented here. These analyses divide the family into five primary monophyletic clades: apostasioid, cypripedioid, vanilloid, orchidoid, and epidendroid orchids, arranged in that order. These clades, with the exception of the vanilloids, essentially correspond to currently recognized subfamilies. A distinct subfamily, based upon tribe Vanilleae, is supported for Vanilla and its allies. The general tree topology is, for the most part, congruent with previously published hypotheses of intrafamilial relationships; however, there is no evidence supporting the previously recognized subfamilies Spiranthoideae, Neottioideae, or Vandoideae. Subfamily Spiranthoideae is embedded within a single clade containing members of Orchidoideae and sister to tribe Diurideae. Genera representing tribe Tropideae are placed within the epidendroid clade. Most traditional subtribal units are supported within each clade, but few tribes, as currently circumscribed, are monophyletic. Although powerful in assessing monophyly of clades within the family, in this case rbcL fails to provide strong support for the interrelationships of the subfamilies (i.e., along the spine of the tree). The cladograms presented here should serve as a standard to which future morphological and molecular studies can be compared.

An expanded plastid DNA phylogeny of Orchidaceae and analysis of jackknife branch support strategy
Article
Full-text available
  • Jan 2004
An expanded plastid DNA phylogeny for Orchidaceae was generated from sequences of rbcL and matK for representatives of all five subfamilies. The data were analyzed using equally weighted parsimony, and branch support was assessed with jackknifing. The analysis supports recognition of five subfamilies with the following relationships: (Apostasioideae (Vanilloideae (Cypripedioideae (Orchidoideae (Epidendroideae))))). Support for many tribal-level groups within Epidendroideae is evident, but relationships among these groups remain uncertain, probably due to a rapid radiation in the subfamily that resulted in short branches along the spine of the tree. A series of experiments examined jackknife parameters and strategies to determine a reasonable balance between computational effort and results. We found that support values plateau rapidly with increased search effort. Tree bisection-reconnection swapping in a single search replicate per jackknife replicate and saving only two trees resulted in values that were close to those obtained in the most extensive searches. Although this approach uses considerably more computational effort than less extensive (or no) swapping, the results were also distinctly better. The effect of saving a maximal number of trees in each jackknife replicate can also be pronounced and is important for representing support accurately.
