中国凤尾蕨属（凤尾蕨科）的孢粉学与叶表皮形态学研究
Study on spore and leaf epidermis morphology of Pteris (Pteridaceae) from China
摘要
Abstract
Forty‐four taxa in Pteris(Pteridaceae) from China were selected for spore and leaf epidermis morphology studies .Spore morphology is stable at the genus level .Pteris can be divided into six groups based on the equatorial flange and lophate ornamentations .However ,its spore morphology is not consistent with its sporophyte morphology . Stoma types are quite stable at the genus level and the species level .Polocytic type and axillocytic type are the prima‐ry stoma types for most Pteris species .However ,stoma density ,size and length to width are unstable at the genus level and the species level .So they are valueless for taxonomy .Due to the high repeating frequency in Pteris ,primary stoma types are less valuable for species delimitation than for genus delimitation .Based on these ,systematic relations of confusing species are discussed .关键词
