Abstract: Fifteen species of pteridophytes are recorded for the first time from Hainan Island. They are Aleuritopteris squamosa, Allantodia deoderleinii, Allantodia virescens, Antrophyum formosanum, Asplenium sampsonii, Botrychium daucifolium, Dryopteris fuscipes, Dryopteris pacifica, Lindsaea javanensis, Loxogramme assimilis, Lygodium subareolatum, Pteris longipes, Pteris longipinnula, Selaginella braunii and Selaginella repanda. So far, some 450 pteridophyte taxa are known to grow in Hainan Island.

Abstract: ten species of Lygodium are enumerated for Malaysia. Of these ten species, L. auriculatum and L. polystachyum were not recorded for Sabah and Sarawak, and L. merrillii was not recorded for Peninsular Malaysia. iNtroDuctioN Lygodium is a pantropical genus comprising c. 40 species. it also occurs in temperate regions (South Africa, u.S.A, Japan, Chile, and New Zealand). Holttum (1959) treated the genus in the family Schizaeaceae. the plants are twining climbers mainly in secondary forest. Fronds of young plants of Lygodium are dichotomously branched, but later fronds develop into a series of alternate unequal dichotomies. the rachis-branches are variously branched and bear leaflets with the sporophores at the ends of their veins. Fronds of larger species may climb to a height of 9-10 m. in the comprehensive account of the genus Lygodium Sw. in the Malay Peninsula, Holttum (1955) listed seven species, namely, L. borneense Alderw., L. circinnatum (Burm. f.) Sw., L. flexuosum (L.) Sw., L. longifolium (Willd.) Sw., L. microphyllum (Cav.) R. Br., L. polystachyum Wall. ex t. Moore and L. salicifolium C. Presl. the genus was revised by Holttum (1959) for Flora Malesiana and a total of 14 species were recognised including the seven species listed above in the Malay Peninsula. For Borneo, Holttum (1959) recognised eight species, namely, L. microphyllum, L salicifolium, L. flexuosum, L. borneense, L. longifolium, L. circinnatum, L. merrillii Copel. and L. auriculatum (Willd.) Alston. the last two species were only recorded from Sarawak and Kalimantan, respectively. Recently, L. japonicum (thunb.) Sw. was recorded from Sabah, probably introduced from the Philippines (Shim, 1992). this brings the total number of Lygodium species in Malaysia to ten as listed in Parris & Latiff (1997).
