The vegetation developing in the Yukidori Valley, Langhovde, East Antarctica, was investigated as based upon the structure of moss colonies of 120 samples in vertical cross-section. These specimens have been housed in the herbarium of National Institute of Polar Research (NIPR). We tried to use herbarium specimens to attempt a Classification of the structure of the cushion by determination of the specific composition, thickness of the cushion, differentiation of surface green part and brown part, and decomposed part. In addition, the structural elements such as rhizoidal zones and epiphytic condition of cyanobacteria and imperfect lichens seen in the cross-section are examined and measured. and discussed these scientific significance.These colonies were consisted of pure colonies. and mixed colonies composed of two or three moss species. Each colony was classified into flat type and uneven type. The significance of the green part, brown part and sandy soil mixed with humus which were seen in the vertical cross-section. and epiphytic organisms and rhizoidal layers on the surface or in the inside of cushion were considered. The relationships among the thickness of colony, ratio of green and brown parts, sandy soil part and rhizoidal layers were analyzed.

根据120个苔藓群落垂直剖面的结构，对东南极朗霍夫德雪取谷的植被发育进行了研究。这些标本已保存在美国国家极地研究所（NIPR）的植物标本馆中。本文利用植物标本，通过测定其具体成分、厚度、表面绿色部分与褐色部分的区别以及分解部分，对该植物的结构进行了分类。此外，还对剖面中的蓝藻和不完全地衣的根际带、附生状态等结构要素进行了分析和测量。这些菌落由纯菌落组成。以及由两种或三种苔藓组成的混合群落。每个菌落分为平坦型和不平坦型。垂直剖面上出现的绿色部分、棕色部分和桑迪混腐殖土的意义。并考虑了垫体表面或内部的附生生物和假根层。分析了菌落厚度、绿色部分与褐色部分之比、桑迪土壤部分与假根层之间的关系。
