光镜下比较研究了假瘤蕨属(水龙骨科)2系、5亚系36种植物鳞片的显微特征.结果表明:该属植物的鳞片具有3种形状:卵状盾形、卵状钻形和披针形;3种边缘:全缘、微缘毛及纤维状毛.鳞片特征在系间具有一定的区别:不裂系具有卵状钻形或卵状盾形、全缘或具微缘毛的鳞片;羽裂系具有卵状盾形和披针形的鳞片,边缘以具微缘毛及纤维状毛为主.鳞片的形状及边缘具有一定的对应关系.另外,鳞片的边缘与叶片的边缘也有一定的对应关系.该文研究并图示了这两种对应关系.

Characters of scales of 36 species,representing 2 series and 5 subseries of the genus Phymatopteris(Polypodiaceae),are examined by means of light microscopy. There are three types of scale shapes in this genus:ovate-peltate,ovate-subulate and lanceolate. Also three types of scale margin are presented:entire,ciliolate and fimbriate. Scales characters are different between the series:the ovate-subulate or ovate-peltate scales with entire or ciliolate margin often occur in simple series I;while the ovate-peltate and lanceolate scales with ciliate or fimbriate in margin usually present in pinnatifid series II.The correlations among the shape and margin of the scale and between the margins of blade and scale were found. At last,these two correlations were discussed and illustrated.
