Abstract
Three species of Sphagnum are reported for the Hawaiian Islands: S. henryense Warnst., S. palustre L., and S. wheeleri C. Mueller. Sphagnum henryense is reported for the first time from the Hawaiian Islands. One species formerly reported for Hawaii, Sphagnum vitjianum Schimper (= S. perichaetiale Hampe) is excluded. Sphagnum occurs naturally only on two islands: Maui and Hawaii. The Hawaiian Islands are the most remote high volcanic islands in the world. This, along with their small size and tropical setting, suggests that the nat- ural dispersal and successful establishment of Sphagnum would be difficult. Not surprisingly, the Hawaiian Islands have a depauperate Sphagnum flora. Bartram (1933) listed only two species: S. pal- ustre L. (a temperate species having an amphiatlan- tic and amphipacific distribution) and S. wheeleri C. Mueller (endemic to Maui). Andrews (1941) placed S. wheeleri in synonomy with S. compactum DC (a widespread temperate species), primarily be- cause the morphology of the chlorophyll cells and the branch leaf pseudopores were basically identical in both taxa. Consequently, the most recent check- list of Hawaiian mosses (Hoe 1974) cited S. com- pactum and S. palustre as being present. A third species S. vitjianum Schimper (= S. perichaetiale Hampe) was reported by Hoe (1978). With the significant increase in knowledge of the genus as well as a growing interest in the ecology of these plants, an updated treatment appears appro- priate. In this paper we provide a revision of the Sphagnum flora of the Hawaiian Islands. We find three species to be present: S. henryense Warnst., S. palustre, and S. wheeleri. Sphagnum henryense is a new record for the Islands. Sphagnum wheeleri is recognized as being distinct from S. compactum. Sphagnum vitjianum (= S. perichaetiale) is exclud- ed from the flora.
