Abstract
Pandanus sermolliana Callmander & Buerki (Pandanaceae) is described from humid forests in the Galoka mountain chain in northwestern Madagascar. The new species can be easily distinguished from the other members of the genus it most closely resembles, P. insuetus Huynh and P. perrieri Martelli, by several morphological characters including drupes that are incompletely fused, with each of the dome-like carpels separated from the base of the pileus, and stigmas that are sub-vertical or rarely sub-horizontal, slightly spinescent, and raised on an incompletely united base. This distinctive species is rare and is classified as Critically Endangered based on IUCN threat criteria.
期刊介绍:
Novon is a quarterly, peer-reviewed botanical journal whose purpose is to publish articles establishing new nomenclature, including new taxa and new names, for vascular plants and bryophytes. Short papers typifying existing names may also be accepted. Lengthy revisions that primarily describe and discuss known species, while publishing nova incidentally, are not appropriate for Novon. Articles may be written in English or Spanish.
