Abstract

Passiflora menghaiensis (Passifloraceae), a new species from Menghai, Yunnan, China, is described and illustrated. The species is placed in Passiflora subgenus Decaloba, supersection Disemma, section Octandranthus. It is compared with two morphologically similar species in section Octandranthus, P. kwangtungensis and P. geminiflora. Passiflora menghaiensis differs from the preceeding species by the combination of two flowers per inflorescence, the outer series of coronal filaments white, the inner series of coronal filaments light green, and puberulous fruit. A complete morphological description of P. menghaiensis is provided, together with line drawings, photographs, a conservation assessment, and a diagnostic key to fourteen species of Passiflora subgenus Decaloba supersection Disemma section Octandranthus from China.

[Botany • 2019] Manglietia pubipedunculata (Magnoliaceae) • A New Species from Yunnan, China

Manglietia pubipedunculata Q. W. Zeng & X. M. Hu 

in Hu, Zeng, Liu, et al., 2019. 

DOI: 10.1371/journal.pone.0210254 

Abstract

A new species, Manglietia pubipedunculata Q. W. Zeng & X. M. Hu (Magnoliaceae) is described and illustrated from Yunnan, China. In addition to macromorphological examination, we comparatively studied on micromorphology of leaf epidermis, leaf structure, and epidermal cell on the sclerotesta. This new species is similar to M. kwangtungensis in terms of having dense pubescence, however, their pubescence are quite different. Manglietia pubipedunculata has appressed, compressed, shorter and sparser pubescence consisting of single or two cells. Moreover, it differs from M. kwangtungensis by showing shorter and thicker peduncles, longer styles, basal carpels covered with sparsely brown appressed pubescence, and more ovules per carpel. Furthermore, the new species has thinner leaves, brown and rugged surfaces on sclerotesta, and the alveolate cell pattern consisting of pentagon or hexagon cells with papilla on secondary cell wall under the observation by SEM. The phylogenetic analysis from two nuclear PHYA and LEAFY and chloroplast trnH-psbA sequences of 11 taxa reveals that M. pubipedunculata is a distinct species.

[Botany • 2019] Selaginella dianzhongensis (Selaginellaceae) • A New Spikemoss from Yunnan, China

Selaginella dianzhongensis X.C.Zhang

in Shalimov, Zhu, Zhang & Zhang, 2019. 

 DOI: 10.3897/phytokeys.118.30375

Abstract

A new species of spikemoss from Yunnan Province of China, Selaginella dianzhongensis, is described and illustrated based on evidence from gross morphology, micromorphology and molecular phylogeny. S. dianzhongensis is most similar to S. amblyphylla in its habit of creeping stem, leaf size, and obviously dimorphic sporophylls, but is distinct by its ventral leaves ovate-oblong, subcordate at base, basiscopic base entire, axillary leaves ovate and decurrent at base. Molecular phylogeny analysis of three chloroplast gene regions (rbcL, atpI, psbA) shows that S. dianzhongensis forms an independent branch with strong support which is distantly related to S. amblyphlla and S. kurzii, but sister to S. bodinieri which is quite different in habitat of erect or ascending stem and rhizophores restricted to the lower part, and slightly dimorphic sporophyllus.

Selaginella dianzhongensis X.C.Zhang, sp. nov.

Diagnosis: The new species resembles Selaginella amblyphylla in habit and gross morphology, but it is different in stems and branches reddish (vs. stramineous in S. amblyphylla), ventral leaves ovate-oblong, 1.1–2.2 × 0.4–0.8 mm (vs. oblong, 2–3 × 0.6–1.2 mm), base subcordate, basiscopic margin not ciliolate (vs. rounded and margin sparsely ciliolate); dorsal leaves oblique subcordate or cordate at base (vs. obliquely cordate), margin with rather long cilia (vs. denticulate or ciliolate); axillary leaves ovate and decurrent at base (vs. ovate or triangular and obtuse to decurrent at base); strobili 3.2–4.0 × 2.3–3.5 mm (vs. 3.5–10 × 3.2–4.4 mm), ventral sporophylls margin ciliolate, dorsal sporophylls margin denticulate (vs. both sporophylls margin ciliolate).

...

Etymology: Dianzhong means central Yunnan in Chinese: the type locality (Yimen) is in the central Yunnan area which is centered on the Provincial capital city Kunming.

Distribution and habitat: Selaginella dianzhongensis is known only from Yimen county, Yunnan, growing on mossy soils in a mixed evergreen forest, at ca. 1576 m a.s.l. (Fig. 3).

Camellia mingii  S.X.Yang

in Liu, Fang, Liu, et al., 2019. 

 DOI:  10.11646/phytotaxa.393.1.4 

Abstract

Camellia mingii S.X.Yang is described and illustrated as a new species from southeast Yunnan Province, China. It is morphologically closest to C. pubipetala, but can be easily distinguished by its spiral arrangement of bracteoles and sepals; its bracteoles and sepals lunate, reniform or broadly ovate, glabrous inside and densely puberulent outside; its petals orbicular to short elliptic, puberulent on both sides; and its inner filaments puberulen to ca. 2/3 from base. Molecular analyses based on GBSSI sequences also support C. mingii as a distinct species of yellow camellia. It is ‘Critically Endangered’ (CR) according to the IUCN Red List Categories and Criteria.

in Wu, Li, Liu & Liu, 2019. 

 DOI: 10.3897/phytokeys.117.28281

Abstract

Spiradiclis karstana, a new species of Spiradiclis (Rubiaceae) collected from Yunnan, China, is described for the first time. It is morphologically close to S. jingxiensis, but differs from the latter mainly by its inflorescences with 5–9 flowers, its 1.5–2.4 mm long peduncles, its stipules shorter than 1 mm and the 5–12 pairs of secondary veins. The conservation status is assessed as “Vulnerable” (VU) according to the IUCN Red List Categories and Criteria.

Spiradiclis karstana L.Wu, X.Li & Q.R.Liu, sp. nov.

Diagnosis: Similar to S. jingxiensis, but differing from this species by the ovate-triangular stipules less than 1 mm long (vs. stipules linear, 1.5–3.0 mm long), the elliptic to oblong leaf blades (vs. ovate to broadly ovate), the 5–12 pairs of secondary veins (vs. 4–5 pairs) and the inflorescences with 5–9 flowers (vs. inflorescences with 1–2 flowers).

....

Distribution and habitat: Spiradiclis karstana is known only from the crevices of forested cliffs at altitudes ranging from 800 to 1600 m in the karst area of SE Yunnan. This part of Yunnan is covered by evergreen rain forests that are highly similar to those in Indo-Malaysia (Zhu 2013) and are dominated by species from Magnoliaceae, Lauraceae, Dipterocarpaceae and Annonaceae.

Etymology: The specific epithet refers to the habitat of the new species.

Abstract

During recent surveys in Gaoligongshan Mountain Range, Yunnan Province of China, we collected specimens of Scutiger from a montane stream area at an elevation of 3000 m. Subsequent study based on morphological, molecular, and acoustic data reveals that the newly collected specimens represent an unknown taxon and is described herein: Scutiger tengchongensis, new species. The new species can be distinguished from its congeners by a combination of the following characters: (1) relatively small size (adult male SVL 36.0–40.1 mm, n = 8); (2) vomerine teeth absent; (3) dorsum with large prominent, conical-shaped and longitudinal tubercles; (4) large tubercles on dorsum covered by numerous tiny black spines in males in breeding condition; (5) a pair of pectoral glands and a pair of axillary glands present on the chest, and covered by dense tiny black spines in males in breeding condition; (6) pectoral gland about twice the size of axillary gland; (7) inner three fingers with black nuptial spines in males in breeding condition; (8) nuptial spines on first and second fingers larger than those on third finger; (9) black spines on the belly absent; (10) vocal sac absent; and (11) toe webbing rudimentary. The discovery of S. tengchongensis, new species, represents the southernmost record of the genus worldwide, and the new species is the smallest known member of the genus in body size.

Abstract

Despite being recognized as ecologically and biogeographically important, the biodiversity of the Hengduan Mountain Region, particularly along the upper Mekong River, remains poorly understood. Here we describe a new species of Mountain Dragon of the genus Japalura sensu lato Gray, 1853 from the headwater region of the Mekong River in Chamdo, Tibet Autonomous Region, China. The species is recognized as a member of the Japalura flaviceps Barbour & Dunn 1919 complex, and it can be distinguished readily from all congeners by a suite of morphological characteristics, including its dwarf appearance (small body size and disproportionally short tails and short hind limbs), smooth or weakly keeled ventral scales, feebly developed vertebral crests in males, and by the absence of distinct gular spots in males and females. In addition to the description of the new species, we also report morphological variations and range extensions of two recently described congeners along the same river, namely J. iadina and J. vela. We discuss the distribution patterns of the genus in the Hengduan Mountain Region and the urgent conservation priorities for protecting Japalura species along the Mekong River. According to our best available data, we provided IUCN assessments of the three species and propos to list them as nationally protected under the Chinese Wildlife Protection Act.

Etymology. The species name, drukdaypo, was derived from the pronunciation of the Kham Tibetan word that means “dwarf dragon”, which describes the diagnostic dwarf-morphology of the new species. We name the new species using Kham Tibetan in honor of the local culture and people, as well as their positive impacts on wildlife conservation.
Suggested English common name is: Dwarf Mountain Dragon, and the suggested Chinese common name is .... (Pinying: Zhu Pan Xi).

Abstract

Due to the unavailability of specimens and publications in the past, some gaps exist in knowledge of similar species from various adjacent countries. After more recently detailed observations from field surveys and examinations on herbaria specimens, we confirmed the status of Begonia arboreta and B. sonlaensis as synonyms of B. garrettii and B. pseudodryadis from China and Thailand, and from China and Vietnam, respectively. The taxonomic treatment is based on the examination of both available herbarium specimens and living plants from different populations. Taxonomy revision of the allied species is very important for understanding plant diversity in the above neighboring countries.

[Botany • 2018] Bulbophyllum chrysolabium (Orchidaceae, Epidendroideae) • A New Species from Yunnan, China

Bulbophyllum chrysolabium L. Li & D.P. Ye

in Li, Ye & Zeng, 2018. 

 DOI: 10.3897/phytokeys.111.28136 

Abstract

Bulbophyllum chrysolabium, a new species belonging to section Racemosae from Yunnan, China is described and illustrated. The species is related to B. orientale and B. morphologorum, but differs by having the following set of characters: obliquely broadly-based triangular petals with a long filiform apex; lip densely glandular papillose and conspicuously ciliolate along margins; lip auricles well developed, narrowly falcate, tapering to a long sharp point at the apex; stelidia subulate and twisted inwards, slightly exceeding operculum. The conservation status of B. chrysolabium is assessed and taxonomic notes are provided.

Bulbophyllum chrysolabium L. Li & D.P. Ye, sp. nov.

 Diagnosis: Bulbophyllum chrysolabium is distinguished from all known congeners by having the following unique combination of features: obliquely broadly-based triangular petals with a long filiform apex; lip densely glandular papillose on both sides and conspicuously ciliolate along margins; lip auricles well developed, narrowly falcate, tapering to a long sharp point at the apex; stelidia subulate and twisted inwards, slightly exceeding operculum.

Taxonomic notes: Bulbophyllum chrysolabium appears to be related to B. orientale Seidenf. (Seidenfaden 1979: 138), especially in narrowly falcate lip auricles and twisted stelidia, but differs in distinctly longer floral bracts (almost twice as long as the pedicel and ovary); petals with long filiform apices, a rather smaller lip (ca. 2.8 mm long), significantly glandular-papillose and ciliolate at margins; stelidia slightly exceeding operculum and distinctly longer than column. With respect to filiform petals, B. chrysolabium is also superficially similar to B. morphologorum Kräenzl. (1908: 89), however, the latter have a fat, conical protuberance or callus on the front of the column near its base and scape much longer than rachis. In addition, it has subulate, not twisted stelidia, considerably longer than operculum; lip auricles not falcate, but rather obtuse at the apex. A detailed morphological comparison between B. chrysolabium and its allied species is presented in Table 1.

Distribution and habitat: So far known only from Menglian County in southwest Yunnan Province, China, growing as an epiphyte amongst mosses on the tree trunk near the edge of river in rather exposed circumstances in subtropical evergreen broad-leaved forest.

Etymology: The specific epithet comes from the Ancient Greek word chryso- “golden” and the Latin derived labium “labellum”, referring to the golden-yellow lip of the type.

[Botany • 2018] The True Tectaria chinensis (Tectariaceae): Morphology, Distribution, and Allied Species

Tectaria chinensis (Ching & Chu H. Wang) Christenh.

in Dong, Tan, Pham & Phan, 2018. 

 DOI: 10.11646/phytotaxa.376.1.6 

Abstract

Tectaria chinensis is a poorly known species from China, with its type being the sole authentic voucher to date. Recent field observations and morphological comparisons reveal its type being an incomplete frond, which resulted in the constant misinterpretation of some morphological characters and the allied species to T. chinensis. In fact, T. chinensis is a very special species restricted in southern China and northern Vietnam and featured by the unique long and erect caudex and the rare combination of partly free venation and vein-dorsal sori. Phylogenetically, T. chinensis was revealed by our previous analyses of five plastid regions to be in the Ctenitopsis group (Clade III or T. subg. Ctenitopsis), forming a sister clade to the lineage of T. fuscipes. A detailed description, explanatory illustrations, as well as distribution and habitat information of T. chinensis are provided.

Tectaria chinensis (Ching & Chu H. Wang) Christenhusz (2010: 58). 

Basionym:— Ctenitopsis chinensis Ching & Chu H. Wang (1981: 124). 

Type:— CHINA. Yunnan: Hekou, in 1955, elev. 100 m, Department of Biology, Yunnan University (DBYU) 512 (holotype PE!)

....

Distribution:—Restricted to southern China and northern Vietnam. In China: southern Yunnan (Hekou, Jinping, Lüchun, Mengla, and Xichou); in Vietnam: Ha Giang (Cao Bo, Vi Xuyen Distr.), Lao Cai (Nam Xe, Van Ban Distr.). This is the first time to confirm T. chinensis in Vietnam. It is also highly expected to find this species in northern Laos.

Note:— The type of Tectaria chinensis, DBYU 512 (PE), is actually an incomplete frond that consists of a broken stipe and a lamina without basal pinnae (Fig. 1). The lowest pinnae seen on the sheet of type specimen was mistakenly regarded as the basal pinnae by Ching & Wang (1981), which leaded them and later authors (Wang 1999, Cheng 2005, Xing et al. 2013) to associate this species with Ctenitopsis subsageniacea sensu Ching (1938: 311) [= T. austrosinensis (Christ 1907: 145) C. Christensen (1934: 177) (Dong 2017)], a species with the basal basiscopic lobes reduced on basal pinnae. Based on the misinterpretation of T. chinensis, we had never associated our new collections featured by long-erect caudices with T. chinensis because in the new collections the basal basiscopic pinnules of basal pinnae are constantly produced (Fig. 2). On the other hand, of all known species in Tectaria from China T. chinensis is the only dubious species which is poorly presented in herbarium; this fact reminded us to connect our new collections featured by remarkable long caudex with T. chinensis. The overall similarity, especially the consistent venation and sori positions between the new collections and the type of T. chinensis makes it sure that our new collections are just the individuals of T. chinensis. Now it is clear that T. chinensis is with the basal basiscopic pinnules being produced on basal pinnae and is not at all similar to T. austrosinensis.

Abstract 

The cockroach genus Eupolyphaga is revised. Twenty species and two subspecies are recognized, with thirteen species and two subspecies are new to science: Eupolyphaga daweishana sp. nov., E. dongi sp. nov., E. fengi sp. nov., E. hanae sp. nov., E. hupingensis sp. nov., E. maculata sp. nov., E. nigrifera sp. nov., E. nigrinotum sp. nov., E. pilosa sp. nov., E. robusta sp. nov., E. shennongensis sp. nov., E. wooi sp. nov., E. xuorum sp. nov., E. everestiana reni subsp. nov., and E. fengi yongshengensis subsp. nov. Homœogamia sinensis Saussure is placed as a junior synonym of E. sinensis (Walker) and the replaced name E. limbata (Kirby) for Homœogamia sinensis is invalid, the status of Eupolyphaga thibetana (Chopard) is recovered. Male genitalia of species in the genus is described and illustrated. Females and oothecae of some species are described and illustrated. Distribution maps and a checklist of Eupolyphaga are provided. A key to males of Eupolyphaga is given. Plenty habitat photographs are shown.
