Abstract

It is found that the species Cheilolejeunea ceylanica falls within the circumscription of the polymorphic C. trapezia. The only tenable character that distinguishes the former and the latter is the presence of vitta in leaves of the former. Hence, the name C. ceylanica is reduced to a variety of C. trapezia and a new combination C. trapezia var. ceylanica is made here. Figures and photographs are provided to prove the conclusion. Incidentally, var. ceylanica is an addition to the liverwort flora of India from Courtallam in the Southern Western Ghats.

中文摘要

本文將Cheilolejeunea ceylanica處理為C. trapezia之變種，區別此兩分類群的可靠特徵只有一個，即是在C. ceylanica葉內有假脈。因此，C. ceylanica在分類上由種降階成變種，成為一新組合名C. trapezia var. ceylanica。本文也提供手繪圖與照片來支持這樣的分類處理。
