Aponogeton nateshii S.R. Yadav (Aponogetonaceae), eine ungewohnliche, neue Art aus Indien [Aponogeton nateshii S.R. Yadav (Aponogetonaceae), an unusual, new species from India]

Abstract

Aponogeton nateshii S.R. Yadav was described from the Konkan region of Maharashtra State of India. It was found there in a single pond at Jaitapur village in Sindhudurg district of Maharashtra. Later, it was collected from another pond on the lateritic plateau at Chorla in Belgaum district of Karnataka during October 2015 and in one more pond at Mopa in Goa state during September 2016. Most of the species of angiosperms described today are usually of very rare occurrence and when evaluated fall under one of the threatened categories of IUCN. Aponogetn nateshii is presently known by about 1500 to 2000 individuals restricted to three ponds, one at Jaitapur(Maharashtra), Second at Chorla (Karnataka) and third at Mopa (Goa). This species has very distinct embryo morphology unusual for angiosperms. Present communication explains distribution, peculiarities and general biology of it and provides comparative embryo morphology.
