描述了竹亚科牡竹属一新种——长耳吊丝竹(Dendrocalamus Iongiauritus S.H.Chen,K.F.HuangetR.S.Chen)。该种与吊丝竹(D.minor(McClure)ChiaetH.L.Fung)相近似,但该竹种部分节有明显发达的一条主枝,箨耳较大,明显并与箨片基部相连,窄长,横卧于箨鞘两肩,且呈有规则皱褶状,并着生有6~8mm长的波曲燧毛,箨舌高达0.7~0.9cm,呈不整齐撕裂状,上部有灰黄色扁形长毛,易于区别。  相似文献

A clambering bamboo endemic to northern Vietnam is shown to represent a new species, M. trangdinhensis H.N.Nguyen & V.T.Tran (Gramineae: Bambusoideae‐Bambusinae), which is described and illustrated. It is similar to M. tonkinensis in general appearance, but differs by being covered with appressed white hairs, and by auricles lacking or forming a low rim only, smaller leaf blade 20–24 × 2.3–2.5 cm, and smaller glumes 6–7 × 4.0–4.5 mm. A key to all species of the genus is included.  相似文献

繁殖器官在竹类植物的分类学研究中具有重要意义,研究组在广西马山县观察到竹亚科单枝竹属芸香竹正在开花,该文根据观察到的开花状况和采集到的标本解剖观察结果,对其花枝和繁殖器官特征做了详细的中文及拉丁文补充描述。经对比芸香竹与属内已知繁殖器官结构的单枝竹和小花单枝竹的繁殖器官,3个竹种有相同的繁殖器官结构特征,但在小花数目和大小等方面具有差异。繁殖器官比较表明该属竹种的繁殖器官对喀斯特地貌环境有特殊的适应性,也支持依据营养器官差异划分为3个独立竹种。  相似文献

Gelidocalamus stellatus Wen complex includes Gelidocalamus stellatus, Gauritus, Gmonophyllus, Gmultifolius and Gwugongshanensis, indicating the existence of some taxonomic disputes within this taxon. Based on 13 main phenotypic traits, in this paper, 13 populations of the complex are investigated and the results show that 1) All 13 characters have some changes between and within populations, of which the maximum is the height under branch with 276%, while the minimum is the ratio of length and width with 64%; 2) In the Jing Gang Mountain population (JGM), seven characters, such as the diameter at breast height, the node number, the height under branch, the leaf length, the leaf width, the ratio of leaf length and width, and numbers of each branch, are relatively stable among 4 different populations, and populations of Gstellatus Wen complex can be distinguished effectively by that seven characters, so it maybe have some worth for the clarification of the complex; 3) Besides that Jiu Yi Mountain population (JYM) and Xiao Long Gui population (XLG) share the same or similar traits with that of JGM, there have many remarkable differences between other populations, such the leaf in Lian Ping Country population (LPC) and Huang He Village population (HHV), the culm in Wu Gong Mountain population (WGM) and the numbers of each branch in Gan Zi Depression population (GZD) and Rong Jia Cavity population (RJC). With the observation of the culm sheath and the abaxial epidermis of leaves, the taxonomic position of some populations is discussed. Our results still indicate that Gmultifolius (Huang He Village population) and Gauritus may be null and void. Furthermore, we proposal Gwugongshanensis (Wu Gong Mountain population) and Gmonophyllus (Jiu Yi Mountain population) should be as a taxon under Gstellatus.  相似文献

永安竹类植物及其区系研究   总被引:1,自引:0,他引:1  
经调查,永安天然分布的竹类植物有11属63种(含变种、变型),属种分别占中国总数的28.2%和11.4%,占全省的64.7%和48.8%。其中红舌唐竹、湖南箬竹、毛箨茶秆竹、黄槽毛竹等4种为福建省竹类分布新记录。经类群分析表明,永安竹类植物以单轴散生和复轴混生类型为主,具明显的由丛生竹向散生竹过渡特性,是散生竹类和混生竹类的分布中心。区系地理分析表明,永安竹类植物有5个分布区类型(含亚型),其中东亚成分占首位。  相似文献

城隍竹——福建竹亚科一新种   总被引:1,自引:0,他引:1       下载免费PDF全文
报道了竹亚科(Bambusoideae)少穗竹属(Oligostachyum Z.P.Wang et G.H.Ye)一新种——城隍竹(O. heterophyllum M.M.Lin)。该新种分布于我国福建西部,它与糙花少穗竹[O.scabriflorum(McClure) Z.P.Wang et G.H.Ye]相似或近缘,但秆小,直径不超过1.5 cm;秆箨淡紫绿色,背面具有瘤基刺毛,无斑点,无白粉,亦无焦边,基部密被细刚毛;箨片直立,基部不收缩;箨舌淡禾秆色;叶鞘被细微柔毛而与后者相区别。  相似文献

Micromorphological characters of leaf epidermis of 16 published species from Schizostachy um Nees and its allies ( including Melocanna Trin. , Pseudostachyum Munro, Leptocanna Chia et H. L. Fung and Cephalostachyum Munro) were examined by both light and scanning electron microscopies. The results indicated that the papillae forms and distributional patterns on the abaxial surface were taxonomically informative at the generic level. The characters of papillae did not support Schiz ostachyum sensu lato; meanwhile, it was supported that Melocanna, Pseudostachyum and Cep halostachyum were better to be treated as separate genera respectively. Furthermore, it seemed to be more appropriate to place Leptocanna chinensis and Schizostachyum sanguineum in Cep halostachyum; and to place Cephalostachyum pergr acile and C1 virgatum in Schizostachy um .  相似文献
