Two new species of Yushania (Poaceae: Bambusoideae) from South China,with a taxonomic revision of related species

Two new species of Yushania (Poaceae, Bambusoideae, Arundinarieae) are described and illustrated from Hunan, China. Yushania longshanensis D.Z. Li & X.Y. Ye is distinguished from related species (Y. confusa, Y. angustifolia and Y. pachyclada) by having a thinner culm (0.2–0.3 cm in diameter), glabrous sheath scar, no oral setae, a large glabrous leaf blade (10–20 × 0.9–1.3 cm) and 3–4 pairs of secondary veins. Yushania stoloniforma D.Z. Li & X.Y. Ye has a distinctive scrambling habit, which differs from its putative close allies. Both of these two new species have a solitary branch at the basal nodes and can be assigned to Yushania sect. Yushania based on morphological features. Additionally, we treated Yushania gigantea T.P. Yi & L. Yang as a new synonym of Y. elevata T.P. Yi and renamed Y. microphylla T.P. Yi & L. Yang as Y. weiningensis D.Z. Li & X.Y. Ye.     

竹亚科刚竹属植物的修订(Ⅳ)——Phyllostachys hispida的恢复及其近缘种的分类

在模式标本考证、居群调查和引种栽培的基础上,确认毛壳竹(Phyllostachys hispida S.C.Li,S.H.Wu et S.Y.Chen)与乌竹(P.varioauriculata S.C.Li et S.H.Wu)在新秆性状、秆箨颜色、箨舌高度及颜色、叶鞘毛被上有较大的区别,应作为独立的竹种看待。小叶光壳竹(P.varioauriculata var.glabrata G.H.Lai)也因新秆下部一段呈扁圆形、秆箨基部具长柔毛,叶片很小等特征而明显不同于乌竹,应提升为一个独立的竹种,但由于存在晚出同名问题而给出新名称P.microphylla G.H.Lai。同时还描述了毛壳竹的一新变种,即光壳竹(P.hispida var.glabrivagina G.H.Lai)。日本所产的姬淡竹与毛壳竹属于同一种系,因其学名P.humilis Muroi为一裸名,应予废弃。     

Primulina duanensis sp. nov. (Gesneriaceae) from Guangxi,China

Wang) Yan Liu in having narrowly ovate to ovate leaf blade, leaf blade margin interrupted shallowly crenate, broadly lanceolate bracts, being 1–3‐flowered and possessing hairs on the upper part of the anthers where connected with the filaments; from P. shouchengensis (Z. Y. Li) Z. Y. Li in having narrowly ovate to ovate leaf blade, leaf blade margin interrupted shallowly crenate, broadly lanceolate bracts and possessing hairs on the upper part of the anthers where connected with the filaments.     

Rubia austrozhejiangensis sp. nov. (Rubiaceae) from Zhejiang,China

Rubia austrozhejiangensis Z. P. Lei, Y. Y. Zhou & R. W. Wang, a new species of Rubiaceae from China, is described and illustrated. The new species is similar to R. ovatifolia Z.

Compared to R. argyi, the new species has cylindrical, not quadrate‐angled stems and branches, leaf blades that are long‐ovate to ovate‐lanceolate, 3–5‐veined, and slightly reflexed corolla lobes. In R. argyi, stems and branches are quadrate‐angled or winged, the corolla lobes are spreading, and the mericarps are 5–7 mm in diameter.
