Liverwort (Marchantiophyta) belong to broad bryophyte group in the Plant Kingdom.
They are small in size and prefer moist habitat with high humidity although they can
survive under harsh conditions. Generally, many works and floristic studies on the
flora of moss have been conducted intensively, while research on liverworts and
hornworts are very lacking in Malaysia. Thus far, only two species of liverworts are
recorded for the state of Terengganu. Hence the present study is the first attempt to
collect and document all the species of liverwort in mangrove forest particulary from
Setiu Wetlands. This study aimed to identify all the liverwort species and to prepare
complete taxon checklist of mangrove forest. In this study, four genus were identified
viz. Archilejeunea, Acrolejeunea, Thysananthus and Cheilolejeunea. The preliminary
result showed that the liverwort genera were significantly different in the three
different islands in Setiu Mangrove Forest. Acrolejeunea is the largest genus with
35.3% from the total number of liverwort found in Setiu Mangrove Forest. Pulau
Telaga Tujuh had the highest number of genera. Meanwhile in Pulau Nyor,
Acrolejeunea showed the highest result compared to Pulau Layak and Pulau Telaga
Tujuh. Archilejuenea are only found at Pulau Telaga Tujuh. A conspectus of genera,
keys to genera and species of liverworts found in three different islands in Setiu
Mangrove Forest and the description of each taxa are presented. The main habitat
utilised by the liverworts in Setiu Mangrove Forest is corticulous with four genera.
