Distribution of Holttumochloa (Poaceae: Bambusoideae) in China with description of a new species revealed by morphological and molecular evidence.

ABSTRACT: Holttumochloa has previously only been recorded from Malaysia. Here we describe and illustrate a new species, Holttumochloa hainanensis sp. nov., from the lowland montane forests of Diaoluo Mountain on the Island of Hainan, South China. Morphologically, H. hainanensis is similar to Holttumochloa korbuensis, but can be clearly distinguished from it in having larger culms covered by white wax, longer leaf blades, larger pseudospikelets and anthers. Furthermore, molecular phylogeny based on the nuclear gene GBSSI corroborates the identification of the new species and its affinity. The biogeographical significance of the new record of Holttumochloa in South China is also highlighted in this study.

New distribution records of two bamboo species in Yunnan, China with description of the inflorescence for Melocalamus yunnanensis (Poaceae, Bambusoideae).

Project description:Ampelocalamus actinotrichus (Merrill & Chun) S. L. Chen, T. H. Wen & G. Y. Sheng and Neomicrocalamus prainii (Gamble) P. C. Keng are reported with new distribution records in southern and southeastern Yunnan, China, respectively. Ampelocalamus actinotrichus was previously recorded to be endemic to Hainan, China, and Neomicrocalamus prainii to be distributed in southern Tibet and western Yunnan in China, northeastern India, and Burma. The identities of individuals collected in southern and southeastern Yunnan of these two species are confirmed by molecular evidence. The new distribution record of Ampelocalamus actinotrichus provides a case at the species level for confirming floristic affinities of southern Yunnan and Hainan Island in south China. The disjunct distribution of Neomicrocalamus prainii in Yunnan is concordant with the ecogeographical diagonal line from northwestern Yunnan to southeastern Yunnan and this may imply a tropical origin of this species. In addition, the inflorescence of Melocalamus yunnanensis (T. H. Wen) T. P. Yi is described.

Gelidocalamus xunwuensis (Poaceae, Bambusoideae), a new species from southeastern Jiangxi, China.

Project description:Gelidocalamus xunwuensis W.G.Zhang & G.Y.Yang, a new species collected from Xunwu County of Jiangxi Province in China, is described and illustrated. The new species is similar to G. stellatus in the habit, but differs by internodes sparsely hairy with granuliferous warts, culm sheath stiffly hairy, culm sheath blade broadly lanceolate to narrowly triangular, each node with a ring of appressed trichomes below, foliage leaves broadly lanceolate to narrowly oblong, and new shoots occurring in late October.

Chimonobambusasangzhiensis (Poaceae, Bambusoideae), a new combination supported by morphological and molecular evidence.

Project description:This study elucidates the taxonomic position of Indosasasangzhiensis in considering whether it belongs to Indosasa or Chimonobambusa. Based on morphological and molecular phylogenetic evidence, our results explicitly indicated that I.sangzhiensis should be a member of Chimonobambusa, rather than Indosasa, and is a distinct species closely related to C.communis, C.opienensis and C.puberula. Thus, the new combination Chimonobambusasangzhiensis (B.M.Yang) N.H.Xia & Z.Y.Niu is made. A detailed description as well as two color plates of this species are also provided.

Sinosasagracilis (Poaceae, Bambusoideae), a new combination supported by morphological and phylogenetic evidence.

Project description:The results of phylogenetic analysis, based on the whole chloroplast genome and morphological study support the transfer of a long ignored bamboo species, Sasagracilis, to the recently established genus, Sinosasa, in this study. Morphologically, this species differs from all the other known Sinosasa species by having very short (2-3 mm) foliage leaf inner ligules, which is unusual in this genus. A revised description of its morphology and colour photos are also provided.

Yushaniadezhui (Poaceae, Bambusoideae), a new bamboo species from Yunnan, China.

Project description:A new bamboo species, Yushaniadezhui, from Kunming, Yunnan, China is described and illustrated in this paper. The new species used to be misidentified as Y.polytricha. Based on careful comparison of morphological features and molecular phylogeny evidence, we confirmed its identity as a new member of the genus Yushania. Yushaniadezhui resembles Y.maculata, Y.polytricha and Y.weixiensis in several aspects, such as culm height and branch complement structure. However, the glabrous culm leaf sheaths and internodes, the absence of auricles and oral setae on most foliage leaves, except the one-year-old foliage leaves, the pubescence on the adaxial surface of the one-year-old foliage leaves and its limestone habitat preference can readily distinguish this new species from its related taxa. Moreover, we emphasise that individuals from various populations and molecular markers with different inheritance patterns for phylogeny reconstruction should be included in new species discovery, especially in plant groups with complex evolutionary histories.

Two new species of Fargesia (Poaceae, Bambusoideae) from southwestern China.

Project description:Two new species of Fargesia, one from Xizang (Tibet) and one from Yunnan, China, are described and illustrated. Fargesia viridis D.Z. Li & X.Y. Ye is characterized by its densely white powder, nearly solid internodes, yellow setose sheath scar and culm sheaths, and 4-6 leaves of large size. Fargesia purpurea D.Z. Li & X.Y. Ye has thinner culms (0.5-1.4 cm in diameter), a ring of 4-5 mm tall brown setae below nodes, fewer branches, glabrous sheath scar and culm sheaths, differentiated from the related species.

Gigantochloa glabrata (Poaceae, Bambusoideae), a new bamboo species from Yunnan, China.

Project description:Gigantochloa glabrata N. H. Xia & Y. Zeng ex D. Z. Li & Z. C. Xu, sp. nov., a new species of paleotropical woody bamboo has been described and illustrated from Yunnan, China. The new species is morphologically similar to G. albociliata and G. levis, but differs from them by having erect culm sheath blades; culm sheath ligules 4-6 mm high, truncate, denticulate; and with a ring of white tomentum on the intranode and below the node. The new species was mistakenly identified as Gigantochloa albociliata in the Flora of China and was recognised with description of the vegetative characters in 2014, but it was not effectively published. Here, we designate a complete specimen with inflorescence as the type and describe it in accordance with the Code.

Yushania tongpeii (Poaceae, Bambusoideae), a new bamboo species from north-eastern Yunnan, China.

Project description:Yushania tongpeii D.Z.Li, Y.X.Zhang & E.D.Liu, a new species of the temperate bamboo tribe Arundinarieae (Poaceae: Bambusoideae), is described and illustrated from north-eastern Yunnan, China. Yushania tongpeii is characterised by taller branching from nodes 1-2 m above the ground, usually three branches at the node, sparse purple spots and thin white powder on the internode, densely purple-spotted culm sheaths, glabrous margins of culm sheaths and tomentose leaf ligules. Based on the morphological features, this new species is assigned to section Yushania.

Schizostachyum dakrongense (Poaceae, Bambusoideae), a new species from Dakrong Nature Reserve, Vietnam.

Project description:Schizostachyum dakrongense is a new species of woody bamboo from Dakrong Nature Reserve, Quang Tri Province, central Vietnam. It is closely related to S. hainanense but differs by its pseudospikelets having terminal rachilla segments with ciliate margin and 6 bracts; culm sheath with the base of the outer margin having a slight projection below its point of attachment at the node, as well as sheath blades usually less than half as long as the culm sheath proper; and leaf blades pale-puberulent and sparsely pilosulous on the abaxial surface. The new species is described and illustrated here.
