Abstract

LEON, CAROLINA A.  and  OLIVAN, GISELA. LIVERWORTS OF PEATLANDS AND TEPUALIA STIPULARIS (HOOK. & ARN.) GRISEB. SWAMP FORESTS IN ISLA GRANDE DE CHILOÉ (CHILE): KEY FOR IDENTIFICATION. Caldasia [online]. 2014, vol.36, n.1, pp.23-35. ISSN 0366-5232.  http://dx.doi.org/10.15446/caldasia.v36n1.43889.

Bryophytes play a key role in peatland ecosystems; they participate directly in the constitution of peat and in the maintenance of these ecosystems. Nevertheless, the knowledge of this group is highly limited, specifically for liverworts. Therefore, we present a key to determine liverworts, restricted to peatland habitats and swamp forests of Tepualia stipularis (Hook. & Arn.) Griseb. of Isla Grande de Chiloé ( Chile ). This key includes the main reported taxa for these ecosystems and it is based on vegetative characters to facilitate identification. Fifty-two species and 28 genera are included. These taxa belong to 19 families. The best represented families are: Lepidoziaceae, Lophocoleaceae, Plagiochilaceae, and Aneuraceae. Chiloscyphus, Plagiochila, and Riccardia are the richest genera. A separate key for each group with similar characters and alphabetical taxa list are provided.

Keywords : Bogs; Southern South America; bryophytes; hepatics; key.
