Review of Heteroscyphus Schiffn. (Lophocoleaceae, Marchantiophyta) in Cambodia

ABSTRACT

Introduction. The genus Heteroscyphus in Cambodia has been revised based on recent collections by Choi and Bakalin.

Methods. Specimens in the herbarium were studied and the type specimens were reviewed.

Key results and conclusions. The revision of Heteroscyphus in Cambodia revealed seven species, five of which have been recorded for the first time in the country. In Indochina, the taxonomic composition of Heteroscyphus is very uniform from country to country, and the taxa recorded in Cambodia are the same as those recorded in Vietnam and Thailand (there are no Heteroscyphus records from Laos). The only noticeable addition in Cambodia is the record of Heteroscyphus pandei, which is a poorly understood taxon that may be found in other areas of Indochina. All the taxa reported from Cambodia have been reviewed and illustrated, and an identification key is provided.
