Abstract
Oreocharis pilosopetiolata, a new species of Gesneriaceae from southeastern Guangdong, China, is described and illus-
trated. This species resembles O. benthamii var. benthamii, O. benthamii var. reticulata and O. xiangguiensis, but it differs
from these species by its leaf and indumentum characters, which are discussed in this paper.
Introduction
Oreocharis Bentham (1876: 1021) was previously a genus with ca. 28 species, with a predominant distribution in
China (Wang et al. 1998). However, based on molecular data and morphological evaluation, Möller et al. (2011)
demonstrated that the former Oreocharis was phylogenetically closely related to ten mostly small Chinese genera, and
they transferred all species of Ancylostemon Craib (1920: 233), Bournea Oliver (in Hooker 1893: 2254), Dayaoshania
Wang (1983: 319), Deinocheilos Wang (1986: 1), Isometrum Craib (1920: 250), Opithandra Burtt (1956: 162),
Paraisometrum W.T.Wang (in Weitzman et al. 1997: 431), Thamnocharis Wang (1981: 485) and Tremacron Craib
(1918: 217), and four species of Briggsia Craib (1920: 236) including the type to Oreocharis. After this redefinition,
the new Oreocharis included 88 species, and the further transfers from Briggsia and Ancylostemon to Oreocharis
increased the number to over 100 (Chen et al. 2014; Möller et al. 2014). All of these made the genus one of the
morphologically most diverse groups within Old Word Gesneriaceae
Over the past decade, our and others’ botanical explorations into karst areas of southern China have greatly
improved our knowledge of the diversity of Gesneriaceae, including the description of more than 50 species. However,
only a few new species have been described for Oreocharis, such as, O. dayaoshanioides Yan Liu & W. B. Xu (in
Liu et al. 2012: 393), O. jinpingensis W.H. Chen & Y.M. Shui (in Chen et al. 2013: 312), O. yunnanensis Rossini &
J.Freitas (2014: 283), O. tsaii Y.H. Tan & J.W. Li (in Tan et al. 2015: 188), O. brachypodus J.M. Li & Z.M. Li (2015:
296) and O. striata Fang Wen & C.Z. Yang (in Yang et al. 2015: 369). In October 2012, during a field investigation
in the Lianhuashan Baipanzhu Nature Reserve in southeastern Guangdong, China, we found an unknown plant of
Gesneriaceae growing on rock surfaces. The characters of flower (such as slightly zygomorphic corolla, four separated
stamens, oblong anthers, and so on) indicated that this species belonged to Oreocharis, and is similar to O. benthamii
C.B. Clarke (1883: 63), O. benthamii var. reticulata Dunn (1908: 362) and O. xiangguiensis W.T. Wang & K.Y. Pan
(in Pan 1987: 285), but differs in leaf and indumentum characters. After detailed morphological and literature analyses
(Wang et al. 1998, Li and Wang 2004, Wei et al. 2010, Möller et al. 2011, Chen et al. 2014, Möller et al. 2014), we are
convinced that this is a new species of Oreocharis, which is described and illustrated here.

Diagnosis:Oreocharis pilosopetiolata is similar to O. benthamii var. benthamii, O. benthamii var. reticulata and O. xiangguiensis, but
differs from these species by its chartaceous and elliptic to ovate leaf blades with crenate to serrate margin and cuneate base, 4–6
lateral veins, 1.7–3.6 cm long pedicel, 1.9–2.9 mm long calyx lobes, and dense or spare white or rust-brown villous indumenta on
the petioles, leaf blade, peduncles, bracts, pedicels and calyx lobes. The new species also differs from O. xiangguiensis by its corolla
tube, which is narrowly funnelform and gradually ampliate from base to mouth.

Distribution and habitat:Oreocharis pilosopetiolata is currently known only from Lianhuashan Baipenzhu
Nature Reserve, Baipenzhu Town, Huidong City, Guangdong Province. Two populations have been found there, at the
foot of the mountain (elevation ca. 274 m, 23°05′52.88″N; 115°13′9.78″E) and halfway up the mountain (elevation
ca. 570m, 23°04′53.95″N; 115°13′16.70″E). The plants grow on rock surfaces under evergreen broad-leaved forests at
both sites. The two populations are both less than 1000 individuals.
Phenology:—Flowering from August to September and fruiting from September to October.
Etymology:—The species epithet is based on the indumentum of the peduncle and petiole.
Relationships:—The new species most closely resembles O. benthamii var. benthamii (Fig. 3. A–C), O. benthamii
var. reticulata (Fig. 3. D–F) and O. xiangguiensis (Fig. 3. G–I). The two varieties of O. benthamii, which is the type
of Oreocharis (Möller et al. 2011), have too much overlapping characters that Wei et al. (2010) thought to combine
the two varieties. Similarly, there is too little difference between O. benthamii and O. xiangguiensis, which were also
considered as conspecific by Weitzman and Skog (Wang et al. 1998). But, the leaf and indumentum characters of this
species can easily distinguish from its congeners, and the detailed morphological differences between these species are
described in the diagnostics above and summarized in Table 1.

... The genus Oreocharis Benth. in the Gesneriaceae has recently been greatly enlarged by the inclusion of a number of other genera (Möller et al., 2011). Most of the approximately 113 species are found in China, with a few species also in north-eastern India, northern Myanmar, northern Thailand and northern Indo-China (Möller et al., 2011(Möller et al., , 2015W.H.

Oreocharis uniflora, a new species of Gesneriaceae from Guangdong, China, is described and illustrated. The new species is morphologically similar to O. striata and O. lungshengensis, but differs mainly by its white villous leaf blades and petioles, 1-flowered cymes, shorter peduncles (1.8–3.5 cm long), 3–5-serrate calyx lobes, pale purple to reddish purple corollas, inside with longitudinally purple striations, campanulate-tubular corolla tubes, 4 free stamens, and 1 disc-shaped stigma. Based on the current information, O. uniflora should be considered as ‘Critically Endangered’ (CR), following the IUCN categories and criteria.

Recent molecular phylogenetic studies indicated that no less than ten genera of Gesneriaceae are nested in Oreocharis Benth., and the circumscription of the genus was extended accordingly. The enlarged genus has a distribution predominantly in China. On the basis of recent molecular phylogenetic studies, two further species are transferred to Oreocharis here : Briggsia speciosa (Hemsl.) Craib and Ancylostemon dimorphosepalus W. H. Chen & Y. M.
