Notes on Micronesian Pteridophyta

Fosberg, F. R. (January 1950). "Notes on Micronesian Pteridophyta". 40 (1): 132. doi:10.2307/1544955. ISSN 0002-8444.

Abstract: CERATOPTERIS THALICTROIDES (L.) Brongn. Bull Soc. Philom. Paris (1821): 186. 1821. This widely distributed species, usually found growing rooted in the muddy bottoms of rice and taro pits, has been known from Micronesia since Volkens reported it from Yap in 1901. Both Kanehira and Hosokawa added reports from Palau in 1935, with Hosokawa mentioning also Guam, probably basing this record on Safford's report in 1905. Hosokawa's specimen, no. 6858 (Fo), from Palau represents a very slender plant, with fertile fronds only, but is in all probability correctly referred to this species. Guam specimens from either Safford or Hosokawa have not been seen, but probably belong with the plants discussed as C. gaudichaudii below. To the records of true C. thalictroides may be added Fosberg & Wong 25488 (US, BISH, Fo)2 and Lessa 97 (BISH), both from Mogmog Islet, Ulithi Atoll, Caroline Islands. This is a large robust plant, with fronds up to 45 cm. tall, which was growing in the water of a taro pit. The vernacular name recorded by Lessa is walbwong.
