CARAIPA ANDINA (CLUSIACEAE), A NEW SPECIES FROM THE VENEZUELAN ANDES, AND ITS BIOGEOGRAPHICAL IMPLICATIONS

Caraipa andina (Clusiaceae), uma nova espécie para os Andes da Venezuela e suas implicações biogeográficas

ABSTRACT

Caraipa andina from La Fundación, in the western Andes of Venezuela (Táchira State) is described, illustrated, and its morphological relationship with an allied species is discussed. This new species is morphologically related to C. heterocarpa Ducke, but it differs by the leaf blade shape, size, and dense abaxial papillae; fewerflowered inflorescence; and shorter pedicel, flower buds, petals, and filaments. Phytogeographical information about the La Fundación area is presented. This species represents the first report of this genus in the Venezuelan Andes.

Key words:
Amazonia; Estado Táchira; Guayana; Guttiferae; sandstone outcrops

RESUMO

Caraipa andina foi descoberta em La Fundación, nos Andes Ocidentais da Venezuela (Estado de Táchira) e é aqui descrita e ilustrada, discutindo-se suas afinidades morfológicas com as espécies próximas. Morfologicamente relacionada com C. heterocarpa Ducke, a nova espécie diferencia-se pelo tamanho, forma da lâmina foliar e face abaxial densamente papilosa; inflorescência paucifloras; pedicelos, botões florais, pétalas e filamentos mais curtos. Informações sobre a fitogeografia do local são apresentadas. Esta espécie representa o primeiro registro deste gênero nos Andes Venezuelanos.
