中国水筛属植物叶的解剖研究 A STUDY ON ANATOMY OF BLYXA LEAF IN CHINA 赵佐成 Zao Zuocheng 1 first-author 中国科学院成都生物研究所 中国科学院成都生物研究所 本文对我国水筛属植物4种11个居群的叶片进行了解剖研究,并对其中5个居群的叶片作了扫描电镜的观察。认为叶片大小,叶脉数目,纤维束及其数目,气腔数目等为有分类价值的特征。支持传统分类将我国水筛属植物定为有尾水筛 Blyxa echinosperma（C.B.Clarke）Hook.f.,无尾水筛 B.aubertii Rich.,光滑水筛 B.leioperma Koidz.,水筛 B.japonia （Miq.）Maxim 4种。 This paper states among the accomplisment of the studies on anatomy of leaf of 11 populations on 4 species of Blyxa in China Five populations of them have been observed under scanning electron microscopy. It has pointed that the leaf size, nerve number, fiber bundleand its number, number of air cavity are the characters with classification value. Eleven populations of Blyxa in China were identified into 4 species recognized by traditional classification i, e Blyxa echinosperma （C. B. Clarke） Hook., B. japonica（Miq.） Maxim. 水鳖科 水筛属 解剖 hydrocharitacee Blyxa anatomy 1987-02-01 2021-04-01 2
