Nymphaea abhayana is a species of waterlily endemic to India. [1]
Description
Vegetative characteristics
Nymphaea abhayana is an annual aquatic herb. The leaves are almost all submerged. The lamina is 13-15 cm long, and 16-18 cm wide. The green petioles are glabrous. [2] [3]
Generative characteristics
The 5-6 cm wide flowers float, but never extend above the water surface. The four 3.7-4 cm long, 0.8-1.2 cm wide sepals display prominent venation. The seven 2.9-3.5 cm long, 0.5-0.7 cm wide petals display blueish-purple colouration. The androecium consists of 13 stamens. The flowers have 6-7 stigmatic rays. The globose, 0.7-2 cm wide fruit bears globose seeds. [2] [3]
Reproduction
Generative reproduction
Flowering and fruiting occurs from October to December. [3]
Taxonomy
Publication
It was first described by A.Chowdhury and M.Chowdhury in 2016. [1]
Type specimen
The type specimen of Nymphaea abhayana was collected by Anurag et al. in Gorumara National Park, West Bengal, India, on the 16th of November 2014. [2]
Placement within Nymphaea
It is close to Nymphaea nouchali. [2]
Etymology
The specific epithet abhayana honours Prof. Abhaya Prasad Das [2] of the University of North Bengal and Rajiv Gandhi University. [4]
Conservation
Nymphaea abhayana has a very narrow distribution. [2] It is a rare species. [3]
Ecology
Habitat
It occurs in ephemeral aquatic habitats, which dry up in December. [2]
