对实蕨属Bolbitis的17种植物的孢子进行了扫描电镜观察.根据孢子周壁特征,中国产实蕨属的孢子明显可分为3种类型:A型孢子具网状周壁,B型孢子具鸡冠状-波状周壁,C型孢子具平滑的波状周壁.孢子周壁特征、叶脉式样和叶片顶部的形态是实蕨属中最有价值的分类学性状.根据标本检查,结合野外调查和孢子形态观察,对中国产实蕨属的分类进行了修订,确定中国有实蕨属植物20种和3杂交种,其中包括2个新组合B. fengiana (Ching) S. Y. Dong和B. medogensis (Ching & S. K. Wu) S. Y. Dong,以及2个中国新分布B. costata Ching ex C. Chr.和B. hookeriana K. Iwats..将B. latipinna Ching、B. media Ching & Chu H.

Chiu等8个名称处理为新异名.文中给出了分种检索表、每个种的生境和分布资料、大多数种的特征集要和孢子扫描电镜照片.
對實蕨屬Bolbitis的17種植物的孢子進行瞭掃描電鏡觀察.根據孢子週壁特徵,中國產實蕨屬的孢子明顯可分為3種類型:A型孢子具網狀週壁,B型孢子具鷄冠狀-波狀週壁,C型孢子具平滑的波狀週壁.孢子週壁特徵、葉脈式樣和葉片頂部的形態是實蕨屬中最有價值的分類學性狀.根據標本檢查,結閤野外調查和孢子形態觀察,對中國產實蕨屬的分類進行瞭脩訂,確定中國有實蕨屬植物20種和3雜交種,其中包括2箇新組閤B. fengiana (Ching) S.

A taxonomic revision of the Chinese species of Bolbitis based on studies of herbarium specimens and SEM observation of spores is presented in this paper. Twenty species and three hybrids are recognized in China. Among these, B. costata (C. Presl) Ching and B. hookeriana K. Iwats. are new records to China, B. fengiana (Ching) S. Y. Dong and B. medogensis (Ching & S. K. Wu) S. Y. Dong are new combinations. Eight new synonyms are proposed: B. latipinna Ching, B. media Ching & Chu H. Wang, B. yunnanensis Ching, Egenolfia crassifolia Ching, E. crenata Ching & P. S. Chiu, E. fengiana Ching, E. medogensis Ching & S. K. Wu and E. ×yunnanensis Ching & P. S. Chiu. Based on the perispore features, the spores of Chinese Bolbitis can be clearly divided into three types: type A with reticulate perispore, type B with cristate-undulate perispore and type C with smooth, undulate perispore. The perispore feature, as well as venation pattern and the pattern of apical part of a lamina, are the most important and useful characters for the delimitation of species in Bolbitis.
