Additions and corrections for liverworts and hornworts of Singapore

Since the first record of liverworts and hornworts in Singapore was reported in 1845, the liverwort and hornwort flora of Singapore remain poorly known. Based on the examination on herbarium specimens kept in FH, GOET, SING, and SINU, as well as additional field collections, we found 12 liverworts new to Singapore. The occurrence of Caudalejeunea cristiloba and Jackiella javanica in Singapore is confirmed. Records of Lejeunea parva are erroneous because the voucher specimens from Singapore are assignable to Lejeunea cocoes. A total of 120 liverwort and hornwort species in 45 genera have thus far been recorded in Singapore, including 100 leafy liverworts, 12 simple thalloid liverworts, 5 complex thalloid liverworts, and 3 hornworts. The illustrations of Cheilolejeunea malaccensis, Drepanolejeunea vesiculosa, Jackiella javanica, J. singapurensis, and Lejeunea cocoes are provided.
