河南省湿地藓属的初步研究

在研究标本的基础上,根据配子体和孢子体的外部形态及其解剖结构和文献中对中国湿地藓属(Hyophila)系统位置的主要观点,鉴定出河南省分布有该属植物6种,其中花状湿地藓(H.nymaniana)、四川湿地藓(H.setschwanica)、匙叶湿地藓(H.spathulata)3种为河南省藓类新记录.编制了河南省湿地藓属植物分种检索表,对每个种的生境、分布及识别特征进行了概述.并对湿地藓属的系统演化位置以及该属植物在河南省的分布进行了讨论.

Preliminary Study of Hyophila (Musci, Pottiaceae)in Henan Province, China

This paper reports preliminarily studied results of the genus Hyophila Brid.(Pottiaceae) in Henan Province,China.6 species of the genus have been found in Henan Province.Among them,3 species(H.nymaniana,H.setschwanica,H.spathulata) are new records for Henan Province.According to these specimens,a key to these species is made.The authors summarized the general data on habitats,geographic distributions and main recognizable features of every species.New recorded species have been illustrated.The authors reviewed some standpoints on Hyophila Brid.systemic and evolutional position and the history of classifications of this genus in China.The genus may be an original group,according to possible phyletic trends for characters of mosses.The phenomenon reflects the ancient character of the origin of bryophytes in Henan Province.Henan Province is one of the areas which have abundant Hyophila in China.The specimens are deposited in the herbarium of Hebei Normal University(HBNU) and the herbarium of Jiaozuo Teacher's College.
