<p><strong>Notes on taxonomy and distribution of some liverworts of tropical Asia</strong></p>

Abstract

Eleven noteworthy liverworts are reported from Brunei, Indonesia (Seram), and Malaysia (Sabah). Cololejeunea koponenii and Allorgella zantenii previously endemic to New Guinea are newly reported for Indonesia. The poorly known monospecific genus (Cephalolejeunea) is new to Brunei. Cololejeunea streimannii previously known only from Papua New Guinea is newly found in Borneo. Cheilolejeunea obcordata is discovered for the first time except for the type locality. Porella geheebii is new to Seram. Oil bodies of Cephalolejeunea parvilobula, Cheilolejeunea obcordata, Cololejeunea koponenii, C. streimannii, Leptolejeunea spinistipula, and Pictolejeunea mizutanii are reported for the first time. The photographs of Allorgella zantenii, Cephalolejeunea parvilobula, Cheilolejeunea obcordata, Cololejeunea koponenii, Drepanolejeunea blumei., and Porella geheebii are provided.
