Primulina fengshanensis Fang Wen & Yue Wang, a new species of Gesneriaceae from
Guangxi, is described and illustrated. The new species is compared with the similar P.
linearifolia and P. longgangensis.
The genus Chirita in southern China once con-
sisted of over 140 species, especially in the sec-
tion Gibbosaccus (Li & Zhu 2010). However, it
was recently revised by Wang et al. (2011) and
Möller et al. (2011). Chiritopsis, Wentsaiboea
and all species of the section Gibbosaccus of
Chirita were incorporated into Primulina, which
incipiently had only one species, P. tabacum
(Hance 1883, Wang 1990, Wang et al. 1998, Li
& Wang 2004, Wei et al. 2010).
We collected some specimens of an unrecog-
nized Primulina species in a limestone cave in
northern Guangxi, China, in October 2004. After
a thorough consulting of the relevant literature
(Wang 1990, Wang et al. 1998, Li & Wang 2004,
Li et al. 2006, Li 2007, Wei et al. 2007, Han et
al. 2008, Li & Wang 2008, Li & Möller 2009,
Wen et al. 2009, Wei et al. 2010, Li & Zhu 2010,
Xu et al. 2010, Huang et al. 2010) as well as
herbarium specimens, we concluded that our
specimens represent a new species of Primulina,
which is described and illustrated here.

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.

When the name Taxus chienii W.C. Cheng (Taxaceae) was published, three gatherings (S. Chen 1384, S. Chen 3024, and Y.Y. Ho 3166) were indicated as the types. Recently, Lin & Chao (2007) designated a duplicate of S. Chen 1384 at PE as the lectotype. However, they overlooked that Law (1948) had previously indicated another gathering Y.Y. Ho 3166 as the “type”, effectively lectotypifying the name. According to the Art. 9.17 of the ICN, Law’s lectotypification must be accepted as the first-step lectotypification and, as such, has priority over that by Lin & Cao. Here, a duplicate of Y.Y. Ho 3166 at NAS is designated as the second-step lectotype of the name Taxus chienii.

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.

A new species of Primulina is described and illustrated from southern China (Guangxi zhuang Autonomous Region) as P. guizhongensis. This new species is similar to P. spadiciformis based on morphological characters. Sequences of nuclear ribosomal internal transcribed spacer (ITS) region and the plastid trnL-F intronspacer (trnL-F) from the new species and its 22 relatives are used to resolve generic placement of the new species in Primulina. In spite of three species are vastly different in morphology, the molecular evidences showed that the closest relatives of P. guizhongensis are P. mollifolia and P. luochengensis. The conservation threat analysis is summarized according to the IUCN Red List Categories and Criteria.
A new species of Gesneriaceae, Primulina hunanensis, is described and illustrated from southern Hunnan, China. 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.

A new species of Gesneriaceae, Chirita longicalyx J.M. Li & Y.Z. Wang, is described from Guilin, Guangxi province, China. It resembles C. depressawith its short peduncles, but is easily distinguished from the latter by its toothed calyx and densely bearded anthers. It is also morphologically similar to C. fimbrisepala, but differs from it in having longer lanceolate-line-bracts and shorter peduncles with flowers hidden by rosette leaves.

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.
Chirita nandanensis S.X. Huang, Y.G. Wei & W.H. Luo sp. nova (Gesneriaceae) is described and illustrated from Guangxi, China. The new species is similar to C. floribunda in the leaf and flower shape, but differs by its leaves being densely villous on both surfaces and along the margin, and by having villous pedicels and a 2-parted stigma.
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.
Chirita leprosa Yan Liu & W. B. Xu, a new species of Gesneriaceae from Guangxi, China, is described and illustrated. The new species is similar to C. wangiana Z. Y. Li, but differs by the leaf blade being elliptic to broadly elliptic, bracts broadly ovate, corolla pale yellow, filaments ca 9 mm long, geniculate near the middle, staminodes 3, and by a different flowering period (Oct–Nov).
Chirita guihaiensis sp. nov. (Gesneriaceae) is described and illustrated. Chirita guihaiensis resembles C. macrodonta D. Fang & D. H. Qin, but is distinguished by its entire bracts, lack of tri-nerved sepals, dark purple corolla, and broader corolla tube with purple stripes inside and with the orifice 1.2–2 cm in diameter. However, C. guihaiensis may also be mistaken for C. rotundifolia (Hemsl.) Wood. and C. cordifolia W. T. Wang, but it differs from all these species as in the key presented in the paper.
A new species of Gesneriaceae, Chirita maguanensis Z.Y.Li, H.Jiang & H.Xu, is described from Southern Yunnan, China. It is similar to C. eburnea Hance in its large, fleshy, white and parallel-veined bracts, but differs by having broad and oblique leaves with a repand–crenate or crenate margin, suborbicular bracts, membranous, white calyx, purple corolla-tube, 2-parted lower lip of stigma and lower disc. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 269–273.
sp. nova (Gesneriaceae) is described from Yunnan, China, and illustrated. We investigated its phylogenetic relationships within the Chirita-Chiritopsis group using separate and combined data from the nuclear ribosomal Internal Transcribed Spacer (ITS) and the chloroplast trnL-F sequence for twenty-three species in different sections of Chirita and Chiritopsis. Chirita auricu-lata belongs to section Chirita. This is an unexpected phylogenetic position because the new species has a calyx divided almost to the base, ovoid ovaries shorter than the styles, small plant bodies, and small flowers, characters that typically define Chiritop-sis. Its position close to C. pumila is supported by its annual stems and membranous leaves.
