Indian screw pine relations Pandanaceae represents 3 genera, within which genus Pandanus and Benstonea are disbursed in hotspots in India – the Western Ghats and the Northeast Himalayan sector. For the 1st time, Indian Pandanaceae has been assessed for its taxonomic prestige and phylogenetic dating. The huge survey by means of the authors ended in the invention of 3 new Pandanus species (two from the Western Ghats and one from the Northeast Himalaya). the current taxonomic revision proven overall variety of Pandanus species to fourteen which are allotted within the Southern India (9 species) and Northeast Himalayan quarter (5 species). Genus Benstonea is represented via species, one from Southern India and one other species universal to either areas. an in depth species id key's given besides conservation prestige of every species following IUCN purple record different types and standards (2001). The learn published that, out of sixteen Pandanus and Benstonea species, six species are less than threatened categories.
In contemporary years, a chloroplast DNA-based molecular phylogenetic technique has been to appreciate the evolutionary dating one of the plant species. The interrelationship one of the 14 Pandanus species at infrageneric point has been labored out utilizing this procedure, which has resulted in the rearrangement of a few species to the subgenera proposed through Stone (1974). furthermore, the shut courting among Pandanus and Benstonea has been proven and the interrelationship of Indian Pandanus genus in worldwide context is given. This booklet additionally describes the industrial significance of every Pandanus species.
