Description

Flowering Nymphaea heudelotii specimen cultivated in the Botanischer Garten und Botanisches Museum Berlin

Vegetative characteristics

Nymphaea heudelotii is a relatively small species.[3][4][5] It has 1 cm wide, elongate rhizomes.[2] The ovoid to round leaves with an entire margin display reddish colouration on the adaxial surface, as well as red colouration with purple spotting on the abaxial surface. The lobes of the leaf have a rounded apex.[6] The petioles is 20 cm long and slim.[2]

Generative characteristics

The small blue to white flowers are 3-5 cm wide.[7] The peduncle is 30 cm long and holds the flowers 5 cm above the water surface.[2] The gynoecium consists of 4-10 carpels.[8] The globose fruit bears elliptic-globose, smooth seeds.[6] The flowers have a very sweet fragrance.[2]

Cytology

The chromosome count is n = 14.[9]

Reproduction

Taxonomy

Publication

It was first described by Jules Émile Planchon in 1853.[2]
