Contribution to the bryological flora of Argentina. Sphagnum perichaetiale Hampe. and S. recurvum P. Beauv. (Sphagnaceae).

Sphagnum perichaetiale Hampe and S. recurvum P. Beauv. are reported as new to Argentina based on collections from the Corrientes province. The presence of S. recurvum in this province is the southernmost locality in America. Sphagnum magellanicum Brid. and S. cuspidatum Ehrh. ex Hoffm. should be excluded from the bryological flora of the province of Corrientes. Descriptions, illustrations, SEM photographs, habitat, ecology and distribution are given. [ABSTRACT FROM AUTHOR]
