A REVISION OF SCAPHISPATHA (ARACEAE - CALADIEAE) INCLUDING A NEW SPECIES

REVISÃO DE SCAPHISPATHA (ARACEAE - CALADIEAE), INCLUÍNDO A DESCRIÇÃO DE UMA NOVA ESPÉCIE PARA O GÊNERO

ABSTRACT

The formerly considered monospecific genus Scaphispatha (Araceae - Caladieae) is here revised. Scaphispatha robusta E.G.Gonç, a second species for the genus is newly described from the Cerrado Biome and the transition Cerrado-Amazonia. It differs from S. gracilis Brongn. ex Schott by the much more robust petioles and leaves, primary lateral veins drying clearer than the lamina, lateral secondary veins conspicously more prominent than tertiary veins and for the female spadix with 11-15 rows of flowers visible in side view. A key to separate both species is provided, as well as ink illustrations and general remarks on the genus.

Key-words:
Scaphispatha; Cerrado; Caladieae; Araceae; geophyte
