FIGUEREDO CARDONA, LUZ MARGARITA  and  REYES, ORLANDO J.. Floristic richness, endemism and life forms of forests and shrubwoods of coastal terraces of Baconao Biosphere Reserve, Cuba. Caldasia [online]. 2015, vol.37, n.1, pp.31-45. ISSN 0366-5232.  https://doi.org/10.15446/caldasia.v37n1.50818.

The floristic richness, endemism and life forms of eight types of vegetation of the coastal terraces of the Baconao Biosphere Reserve were analyzed. Starting from recollections in field expeditions, the revision of herbarium materials and floristic inventories precedent, the list of vegetable species was elaborated. 757 species belong to 387 genus and 87 botanic families were identified. From all floristic list, 108 were introduced plants an 649 natives, 164 endemics. Shrubwoods and semideciduous forests present the biggest richness of species and endemism; besides high biological similarity, due to the edaphic conditions on that they are developed. The families with more specific richness were Leguminosae (96), Malvaceae (58), Rubiaceae (42), Euphorbiaceae (41), Apocynaceae (34), Boraginaceae (33) and Poaceae (29). The Amazonian-centered floristic elements were predominant (59.2 %), followed by laurasian elements (22.4 %) and unknowed center (18.4 %), with prevalence of Amazonian-centered shrubs. 164 endemic species were classified, of which 58 are pancubans, 45 sectorials, 26 districts and 35 multisectorials. The presence of eight endemic genera was significative, seven monospecific. 35 species were registered as threatened, 22 of them are endemics plants located at protected areas with strict category of handling. Nine life forms were founded, mostly shrubs (282), trees (179), herbs (138) and climbing plants (108).

Keywords : Richness; endemism; forests; shrubwoods; Cuba.
