Conservation Status of Indian Pandanaceae Rahul L. Zanan, Altafhusain B. Nadaf* – American Journal of Plant Sciences, 2013, 4, 51-56 –
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 indi-cated 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.
Summary- Pandanus palakkadensis, a new species from the Palakkad, Kerala state, India is described and illustrated. The new species can be easily distinguished from the other members of the genus it most closely resembles, P. canaranus Warb. and P. furcatus Roxb. in having a drupe with flat pileus, endocarp broadly truncate, concave on either side with distinctly elevated shoulders, a sharp, obliquely pointed stigma and cylindrical fruit. This distinctive species is endemic to the region of collection and is classified as Critically Endangered (CR) based on the IUCN Red List criteria.

Pandanus mangalorensis: a new species of Pandanaceae from Southern India by R. L. Zanan, A. B. Nadaf – Kew Bulletin September 2012, Volume 67, Issue 3, pp 555-559
Summary- Pandanus mangalorensis, a new species from the Mangalore district, Karnataka state, India is described and illustrated. The new species differs from other Pandanus species in having prominent multiple branching, triangular infructescence, drupes arranged on a bony triangular ring, drupe apex pyramidal with acute and bifid style and stigma and central projection extended up to style base. The species appears to be endemic to the collection site and is assigned as Critically Endangered (CR) based on IUCN Red List Categories and Criteria.

Pandanus martinianus (Pandanaceae), a new endemic species from northeastern India by RAHUL L. ZANAN & ALTAFHUSAIN B. NADAF – Phytotaxa 73: 1–7 (2012)-  A new species, Pandanus martinianus (Pandanaceae), from the foothills of West Siang District of Arunachal Pradesh and Dhimaji District of Assam of North-Eastern region of India is described and illustrated. The new taxon is distinguished from other Pandanus species by the dimensions and shape of its syncarp and the arrangement and shape of its drupes and stigmas. A discussion is provided of its morphological affinities, as well as a conservation assessment based on IUCN Red List Categories and Criteria.

Pandanus (Pandanaceae‎) : 2 posts by 1 author.

I have updated eFI (efloraofindia) page on Pandanus (Pl. click).

Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links as far as possible. It’s quite possible that there may be some discrepancy in the accepted names & synonyms taken from other links.

Species discussed so far in efloraofindia are given at the bottom of the page in the form of links against Subpages. On clicking them one can see all the details.

If someone can provide complete list of Indian species with source references it will be wonderful.
Any comments/ corrections are welcome.

Thank you for your mail. We appreciate your efforts in making eflora of India.
We have following concerns in the updated eFI (efloraofindia) page on Pandanus:
1. P. canaranus previously mentioned in the floral database of Tamil nadu  is synonymous to P. unipapillatus (Ref:Indian Pandanaceae – an overview  By Altafhusain Nadaf, Rahul Zanan (2013))
2. Pandanus urophyllus (Not mentioned in the accepted species in Conservation Status of Indian Pandanaceae (2013): It is mentioned in Flora of China but our survey showed that it is not found in sikkim). It should be taken as P. nepalensis
3. Pandanus cookii (Not mentioned in the accepted species in Conservation Status of Indian Pandanaceae (2013): Pandanus cookii is mentioned at below link
:http://www.flowersofindia.Cook’s%20Screw%20Pine.html
………………………..
Therefore, we request you to incorporate these changes in the updated eFI (efloraofindia) page on Pandanus. We will also highly appreciate if you  will let us know these changes.
For more details about Indian Pandanaceae species, we request you to refer to “Tropicos” wherein we have submitted the details with photographs. Please feel free to contact us for any further information on Indian Pandanaceae.

Thanks, … I have made corrections accordingly in efloraofindia.
