Andean genera for the tribe Spathicarpeae (Araceae).

Abstract
Two unispecific Andean genera are described as new to science in the
tribe Spathicarpeae (Araceae) and illustrated,
based on two species formerly placed in the genus
Asterostigma. The genus Incarum is
erected to accommodate A. pavonii that occurs in
Andean Peru, Bolivia and Ecuador, and the new combination Incarum
pavonii is validated. The genus Croatiella is
erected to accommodate A. integrifolium from
Ecuador and the new combination Croatiella integrifolia
is validated. Incarum is considered related to the
Andean genera Gorgonidium and
Spathantheum, whereas Croatiella seems
to be an isolated lineage within the core Spathicarpeae.
The arguments to support these new genera come from cpDNA sequence
data, as well as from biogeographical and morphological
aspects.
