Description

Its leaves are oval or round, 8-12 cm long, with a cluster of bulbils on the top of the leaf stalk. Flowers can reach up to 10 cm in diameter, and appear from approximately September to October.[4] The plant usually grows to a height of 20–80 cm (8–32 inches). It cannot be grown emersed.[5]

Reproduction

Vegetative reproduction

Foliar proliferation of Nymphaea micrantha Guill. & Perr.

New plantlets develop on the adaxial leaf surface through foliar proliferation. The development of those plantlets is halted, while the leaf is still attached. However, once the leaf is detached the plantlets develop fully.[6] In India, which is outside of this species natural range, it has been shown that Nymphaea micrantha predominantly reproduces asexually. In India it has been shown to lack any amount of genetic diversity.[7]

Cytology

The chromosome count is n = 14. The genome size is 889.98 Mb.[8]

Taxonomy

Publication

It was first described by Jean Baptiste Antoine Guillemin and George Samuel Perrottet in 1831.[3]

Natural hybridisation

Together with Nymphaea nouchali var. caerulea, Nymphaea micrantha forms the natural hybrid Nymphaea × daubenyana native to Chad.[9]

Etymology

The specific epithet micrantha, from the Greek mikros meaning small and anthos meaning flower, means small-flowered.[10][11][12]

Uses

Food source

Seeds of Nymphaea lotus and Nymphaea micrantha are eaten in Senegal.[citation needed]
