亚洲东南部特有的新悬藓属的研究

新悬藓属现知共4种,属于蔓藓科,为亚洲东南部特有,我国是该属植物分布的中心。本文提出拟猫尾藓仍归为船叶藓科更合适。

A STUDY ON NEOBARBELLA (MOSSES) OF THE SOUTH-EAST ASIATIC ENDEMIC GENUS

he present paper deals with the classification on the genus Neobarbclla. A key to species is described. This genus consists of 4 species, of which 1 species is new, it occurs only in southeastern Asia. N.piliferu widely elistribules in East Asia. A . conies is a Sino-Himalayan species, but extending to Philipoines and Indonesia. A. amoena and N. serratiacula are endemic species, the former only distributed in Ceylon, another one in China. The morphological characters ol" A. pilifcra and A. comas seem to be comparatively similar each other their branch-leaves are different from slem-leaves. While in N .amoena and A .scrraliacuta, their brach-leaves arc similar to stem-leaves. All of the species of the genus Neobarbellu, the sceondany stems usually hanging, long, pinnately branched. The cells ol the central (issue arc large and thin-walled. Having earelully studies the morphological characters ol this genus, the author finds that, in the species Isotheciopsis sinensis (Broth. ) Broth. the leaves concave, coste none, leaf-cells linear, without papillose, basal cells narrowly rectangular and with thick walls, all of these characters are similar to Neobarbella. On the other hand, the secondary stem arc often short, erect, dendroid and pinnete-branded. It appears to be an abundantly characterized species, probably close to be an abundantly characterized species, probably close to Lernbo phyllaceae. The author considers that Isolheciopsis sincnsis probcibly a transitional taxon between Neobarbella and Lembo phyllaceae.
