Abstract- The Pandanaceae in India are represented by three genera: Pandanus Parkinson (distributed in South and Northeast In-dia and Andaman and Nicobar Islands), Benstonea Callm & Buerki (distributed in South and Northeast India) and Freycinetia Gaudich from Andaman and Nicobar Islands. A detailed survey was carried out from November 2007 to February 2013 along the Peninsular India, North eastern India and Andaman Islands and conservation status of Indian Pandanaceae species was determined following IUCN Red List Categories and Criteria (2001). The assessment indicated that, among the 19 Indian Pandanaceae members, 6 species are falling under threatened category.
P. palakkadensis and P. mangalorensis falls under Critically Endangered,
P. unguifer and P. martinianus under endangered and
P. diversus and B. thwaitesii under vulnerable category.
P. furcatus, P. unipapillatus, P. odorifer, P. kaida, P. leram, P. nepalensis and B. foetida, F. sumatrana and F. rigidifolia fall under Least Concern category.
P. emarginatus under Data Deficient category and
P. amaryllifolius, P. sanderi and P. dubius as exotic species.
Based on our study, we re- commend 6 threatened species to include in the IUCN Red List.
Benstonea Callm. & Buerki (Pandanaceae): characterization, circumscription, and distribution of a new genus of screw-pines, with a synopsis of accepted species by Martin W. Callmander, Porter P. Lowry II, Félix Forest, Dion S. Devey, Henk Beentje & Sven Buerki- Candollea 67(2) : 323-345 (2012)-
Abstract– Pandanaceae, a palaeotropical monocot family of c. 700 species, comprises four currently recognized genera: Freycinetia Gaudich., Martellidendron (Pic. Serm.) Callm. & Chassot, Pandanus Parkinson and Sararanga Helms. Within Pandanus (c. 500 spp.), species of sect. Acrostigma Kurz [one of four sections comprising subg. Acrostigma (Kurz) B. C. Stone] possess highly distinctive morphological features (viz. sharp spiniform, linear styles with the stigmatic groove on the abaxial side of the style and a staminate flower reduced to 1 to 3 stamens) shared with two other species (likewise belonging to subg. Acrostigma but originally placed in sect. Fusiforma B. C. Stone) that separate them from all other congeners. Based on morphology, biogeography, and recent inferences from plastid DNA sequence data, we place these distinctive species in a new genus, Benstonea Callm. & Buerki, making the necessary new combinations for the 50 recognized species, accompanied by six lectotypifications, one epitytification and two neotypifications, and placing seventeen names in synonymy. A generic key is provided to facilitate distinguishing Benstonea from the four other genera of Pandanaceae. Comments are provided on the distribution, ecology and typification of each accepted species.
