Abstract
Primulina guigangensis, a new species found in the limestone area of Guigang city, Guangxi, China is described and
illustrated. It is most similar to Primulina yunfuensis, but can be distinguished from the latter by several distinct
characters in calyx, corolla, filament, stigma and phenology. The detailed morphological characters together with
illustrations, diagnostic comparisons and habitat etc. are presented.
Introduction
Chirita, with over 150 species, is a large genus of Gesneriaceae. Most species of the genus have a narrowly
restricted distribution in south China, particularly in the limestone areas of Guangxi Zhuang Autonomous
Region, where dozens of new species have been discovered and identified recently (e.g. Wei et al. 2007, Xu et
al. 2008, Li & Möller 2009, Huang et al. 2010, Li & Zhu 2010, Xu et al. 2010, Huang et al. 2011, Wu et al.
2011, Xu et al. 2011a, 2011b). The genus shows large morphological diversity and traditionally has been
divided into three or four sections: section Chirita, Microchirita, Gibbosaccus and Liebigia (Wood 1974,
Wang 1985a, 1985b, Wang et al. 1998, Hilliard 2004, Li & Wang 2004). However, recent molecular studies
consistently pointed out that the genus and its sections (except Microchirita) are not monophyletic and the
genus represents several lineages of independent origin (Wang et al. 2011, Weber et al. 2011). In the light of
molecular studies, Weber et al. (2011) revised the taxonomy of Chirita with its allied genera and classified the
species of Chirita into 5 different genera, Henckelia, Damrongia, Liebigia, Microchirita and Primulina, and
abandon the genus name of Chirita.
Recently, a tourist found a population of Chirita-like plants in Zhangmu town, Guigang city, Guangxi,
China and resort to us for the identity. After consulting the relevant literature (e.g. Li & Wang 2004, Wei et al.
2010) and herbarium specimens, we found the gross morphology of these newly discovered plants to be most
similar to Primulina yungfuensis (W.T.Wang) Weber (2011: 767), previously Chirita yungfuensis Wang
(1987: 125), but can be distinguished from that species by several non overlapping or distinct characters in
calyx, corolla, filament, stigma and phenotype. Therefore, the population is assumed to represent an
undescribed new taxon which we describe here. The characters are described and illustrated below.

Distribution, habitat and ecology:—Primulina guigangensis was found growing on a slope, often at
crevices in an open evergreen limestone forest, near Guigang city, eastern Guangxi, China. The region has a
seasonal monsoon climate with periodical shift between aridity and rain. The vegetation is dominated by
shrubs and herbs, which include Tirpitzia ovoidea Chun & How ex W.L.Sha, Ficus tinctoria G.Forst. subsp.
gibbosa (Blume) Corner, Mallotus tenuifolius Pax, Alchornea trewioides (Benth.) Müll.Arg., Decaspermum
gracilentum (Hance) Merr. & L.M.Perry, Cipadessa baccifera (Roth) Miq, Vitex negundo L., Zanthoxylum
armatum DC., Mallotus repandus (Willd.) Müll.Arg, Elaeagnus bockii Diels, Sageretia rugosa Hance,
Callerya nitida (Benth.) R.Geesink, Toddalia asiatica (L.) Lam, Wikstroemia indica (Linn.) C.A.Mey.,
Cassytha filiformis L, Chrysanthemum indicum L., Phtheirospermum japonicum (Thunb.) Kanitz,
Hypodematium crenatum (Forsk.) Kuhn, Adiantum malesianum Ghatak, Selaginella effusa Alston, etcetera.
Phenology:—This new species had been collected in flower from September to November, and fruit from
October to December.
Etymology:—The epithet is derived from the type locality Guigang City, Guangxi.
Distinguishing characters:—Primulina guigangensis is most similar to P. yungfuensis. Shared
characters mainly include leaf with similar shape and indumentum, cyme 2–6-flowered with two bracts.
However, P. guigangensis can be distinguished by its 8–15 cm long peduncle (vs. 4.5–9.0 cm long), calyx
apex acuminate (vs. acute), corolla 2.8–3.5 cm long (vs. 3.8–4.6 cm long), tube narrowly funnelform, 1.8–2.5
cm long, inflated above the mouth (vs. tube tubular, 2.5–3.0 cm long, not inflated), filaments densely
glandular puberulent (vs. glabrous), stigma long elliptic (vs. linear) and flowering in September–November
(instead of March).
Additional specimens examined (paratype):—CHINA. Guangxi: Guigang City, Zhangmu Town, same
locality as type, 3 November 2011, L. Wu & Q. Zhang 3041 (IBK!).

  • Aug 2013
Background: Primulina cardaminifolia Yan Liu & W.B. Xu (Gesneriaceae), a distinct new species with imparipinnate leaves, is described and illustrated from a limestone valley in Guangxi Zhuangzu Autonomous Region, China. To assure its generic placement and phylogenetic affinity, phylogenetic analyses were performed using DNA sequences of nuclear ITS and chloroplast trnL-F intron spacer region. Additionally, somatic chromosome number was counted and pollen stainability was tested. Results: Phylogenetic analyses support its placement in Primulina; however, two phylogenetically distinct ITS sequence types were detected, suggesting a probable hybrid origin. Its pollen stainability is 100% and its chromosome number, 2n = 36, is congruent with all known counts of diploid species of the genus. Conclusion: All available data support the recognition of the new species Primulina cardaminifolia and suggest that it could have derived from homoploid hybrid speciation. Color plates, line drawings and a distribution map are provided to aid in identification.

  • Aug 2012
As a consequence of molecular phylogenetic studies, the monotypic genus Primulina has recently been recircumscribed and expanded to include Chirita sect. Gibbosaccus, Chiritopsis, and Wentsaiboea. Based on phylogenetic analyses of ITS sequences and apparent morphological similarity, we make further transfers of six species of Chirita (C. leprosa, C. lijiangensis, C. ningmingensis, C. luochengensis, C. rongshuiensis, and C. tiandengensis) and four of Chiritopsis (Ch. danxiaensis, Ch. hezhouensis, Ch. jingxiensis, and Ch. longzhouensis) that were neglected or published around or slightly after these recent taxonomic treatments. The proposed nomenclatural changes include one new name, P. pseudolinearifolia, and nine new combinations, P. danxiaensis, P. hezhouensis, P. jingxiensis, P. leprosa, P. lijiangensis, P. longzhouensis, P. ningmingensis, P. rongshuiensis, and P. tiandengensis. The addition of these ten species increases the number of the genus to ca. 150 species, making Primulina one of the largest and morphologically most diverse genera of the Old World Gesneriaceae.

Petrocosmea funingensis (Gesneriaceae): A new species from southeastern Yunnan, China
Article
Full-text available
  • Jan 2013
Petrocosmea funingensis, a new species from southeastern Yunnan, China is here described and illustrated. Based on morphological characters it is assumed to belong to section Anisochilus, because of the shallow or slight split of the corolla lobes with the upper lip being nearly half as long as the lower one. Within the section, the new species is associated with the species from series Iodioides, due to the particularly extensive fusion of the two adaxial lobes and is morphologically most similar to P. huanjiangensis and P. iodioides, especially in floral structure and traits, but can be distinguished from these species by several quantitative and qualitative characters of the leaves, peduncles, calices, stamens, staminodes and styles.

Although the Gesneriaceae has great morphological diversity, the molecular evidence has shown large discrepancies with the traditional taxonomy and suggested that the taxonomic units, probably at generic as well as specific level, could have been overestimated by the synonyms and too trivial division of the species or populations with slightly morphological variations into different genera or species (Weber et al. 2011, Christenhusz 2012). ...
Primulina sinovietnamica (Gesneriaceae), a new species identified by both morphological and molecular characters from the limestone area in Guangxi, China

  • Jul 2012
A new species of Gesneriaceae from Southwest Guangxi, China is described here as Primulina sinovietnamica. This previously unknown species is morphologically similar to P. pungentisepala and P. ningmingensis, but can be distinguished from the latter two taxa by several non-overlapping morphological characters. This hypothesis is consistent with the molecular phylogenetic tree based on sequences of the chloroplast matK gene, confirming evolutionary affinity of the new species to the two morphologically similar taxa. The three sampled individuals from the two presently known populations of the new species cluster together in the phylogenetic analysis, separated from the other two closest taxa by two common base substitutions, confirming the recognition of this new species.

Two new species of Spiradiclis (Rubiaceae), Spiradiclis repens L. Wu & Yan Liu and S. reticulata L. Wu, Q Yuan & Jian‐Ling Li are described and illustrated here. Spiradiclis repens is morphologically similar to S. karstana in having a creeping habit, puberulent stems, elliptic to oblong leaves and slenderly salverform corolla, but differ by having less numerous flowers on linear stipules, terminal cymose inflorescences, peduncles 4.0–12.0 mm long, and corolla lilac or pale pink and glabrous inside. Spiradiclis reticulata is close to S. emeiensis and S. malipoensis in that their capsules are ellipsoid and slightly compressed from both sides, but the former can be distinguished from the latter two by having 2‐lobed stipules, monostylous flowers and slenderly cylindrical corollas.

Morphologically, it is similar to P. cordata ( = Chirita cordifolia), but differs by having much larger leaves, broadly ovate or ovate bracts, 2–12 (–25)-flowers, longer peduncle and purple corolla. It also resembles P. eburnea in the shape of the bracts and the colour of the corolla, but can be distinguished by longer petioles (9–25 cm long), cordate, ovate-cordate or broadly ovate leaf lamina with rounded or obtuse apex, not entire leaf margin, and either cordate or deeply cordate leaf base. Detailed morphological description, diagnostic comparisons, habitat and micro-morphology of seeds and pollen under SEM are presented.

Chirita lijiangensis B. Pan & W.B. Xu, a new species of Gesneriaceae from Guangxi, China, is described and illustrated. It is similar to C. pteropoda, but differs by its leaf blade that is densely pilose on both surfaces; by the leaf base being cuneate to broadly cuneate; by the peduncle, the pedicel and calyx being densely pilose; by the corolla that is purple, 2.2–2.8 cm long, and with a slender, ca. 1.5 cm long tube; by the fila-ments being purple, ca. 8 mm long, and glabrous; by the lateral staminodes that are ca.1 mm long; and by the the pubescent, ca. 4 mm long ovary. In the course of a floristic survey of limestone areas in Guangxi, China in 2009, we collected an interesting plant of Gesneriaceae near the river-side of Lijiang.

Molecular systematics and remodelling of Chirita and associated genera (Gesneriaceae)
Article
Full-text available
  • Jun 2011
The polyphyletic genus Chirita is remodelled after an extensive molecular phylogenetic study of species assigned to it and to other associated genera. Most of Chirita sect. Chirita and the monotypic Hemiboeopsis are amalgamated with Henckelia sect. Henckelia, resulting in a very differently circumscribed genus Henckelia and the synonymisation of Chirita. The remain- ing species of Chirita sect. Chirita are accommodated in the revived genus Damrongia. Chirita sect. Liebigia is recognised as the genus Liebigia. Chirita sect. Microchirita is recognised as the genus Microchirita. Chirita sect. Gibbosaccus is, together with Chiritopsis and Wentsaiboea, included in the originally monotypic and now enormously expanded genus Primulina. The necessary combinations are made and a general list showing the present accommodation of the species previously described under Chirita, Chiritopsis, Hemiboeopsis, Primulina and Wentsaiboea is provided.

  • Jan 2012
A new species of Gesneriaceae, Chirita grandibracteata J.M. Li & M. Möller sp. nova (Gesneriaceae), collected in Hekou county, Yunnan province, is described and illustrated. It is most similar, and probably most closely related, to C. eburnea Hance. The new species differs from the latter by having large round leaves with appressed hairs, two rows of dense long hairs on the adaxial border of the two anther-thecae, a triangular stigma lobed for more than half of its length and with an acute or acuminate apex, three glabrous staminodes, and fruits 2.8 cm long.

A revision of Chirita sect. Liebigia (Gesneriaceae)
Article
Full-text available
Chirita sect. Liebigia (Gesneriaceae), endemic to Sumatra, Java and Bali, is revised, paying particular attention to inflorescence and anther characters, the latter being illustrated. Whereas a previous worker considered the section to consist of the single species C. asperifolia, the present revision recognizes 12 species. Six are newly described (C. adenonema, C. dissimilis, C. leuserensis, C. praeterita, C. tenuipes and C. tobaënsis), and C. blumei var. cordifolia is given specific rank as C. neoforbesii. Notes on the history and nomenclature of sect. Liebigia are given in an appendix by B.L. Burtt.

Phylogenetic reconstruction of Chirita and allies (Gesneriaceae) with taxonomic treatments
Article
  • Jan 2011
Chirita D. Don, a large genus in the subfamily Cyrtandroideae of Gesneriaceae, has been the subject of much debate whether it is a natural group or not. In addition, the highly heterogeneous Chirita has also been very problematic with regard to delimitation and subdivision. Here we used the nrDNA internal transcribed spacer and cpDNA trnL-F for molecular phylogenetic analaysis, combined with morphological data. Our results suggest that Chirita is an artificial, polyphyletic genus. The most important character that defines Chirita, the dorso-ventrally oblique and bilamellar stigma, has evolved convergently in different clades of diandrous Cyrtandroideae. Chirita sensu strict only includes the species of Chirita sect. Chirita, whereas Chirita sect. Microchirita is an independent clade located at the basal node of the phylogenetic tree. Chirita sect. Liebigia is closely related to Didymocarpus with an entire stigma unlike other species of Chirita. The species of Chirita sect. Gibbosaccus, Chiritopsis, Primulina, and Wentsaiboea form a monophyletic group that is sister to a strongly supported clade comprising four monotypic genera Paralagarosolen, Calcareoboea, Petrocodon, and Tengia. We further analyzed the morphological evolution of Chirita and identified a series of morphological synapomorphies for the monophyletic groups revealed herein, and thereby provide a taxonomic treatment in this study.
