The Bryophytes of Barbados.

Barbados is located at 13o10’N, 59o35’W, about 150 km east of the Lesser Antilles. The island has a land mass of approximately 432 square kilometres and is primarily coralline in nature. Barbados has a tropical climate with a mean temperature range of 24 to 28oC. There are two major seasons; the dry season (January to May), and a wet season (June to December).
The last effort to document bryophytes from Barbados was carried out by Winona Welch and Howard Crum in 1969. Including that study, 62 species have been recorded from the island. A recent survey of a variety of habitats in Barbados yielded 43 species (35 mosses, 6 liverworts, 2 hornworts). Of the current Barbadian species 35% are new records for Barbados. In addition, 30% of the current Barbados species have not been recorded from the Lesser Antilles.
Of the genera observed, Fissidens was the most diverse with eight species. Other genera including Barbula, Bryum, Cyrto-hypnum, Philonotis, Plagiochila, and Weissia were represented by two or three species. All other genera were represented by one species.
The annotated checklist provides information on the bryophytes presently occurring in Barbados, those not recorded previously from the island, and those not recorded from the neighbouring Lesser Antilles.
