Vegetative characteristics[edit]

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[edit]

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[edit]

The chromosome count is n = 14.[9]

Reproduction[edit]

Vegetative reproduction[edit]

Nymphaea heudelotii has been reported to be viviparous starting from its second year of growth.[10]

Taxonomy[edit]

Publication[edit]

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

Type specimen[edit]

The type specimen was collected by M. Heudelot in Senegal in 1837. It is part of the collection of the National Museum of Natural History, France.[11]

Conservation[edit]

The IUCN conservation status of Nymphaea heudelotii is Least Concern (LC).[1]

Ecology[edit]

Habitat[edit]

It occurs in small lakes, rivers, wet grass savannahs, riparian forests,[12] and in shallow flowing streams.[8] In shallow ponds within the seasonally wet savanna of Gabon, it occurs sympatrically with Websteria confervoides, Nymphoides forbesiana, Eriocaulon nadjae, and Utricularia benjaminiana.[13] Additionally, at elevations between 1120 and 1200 meters above sea level, this species can be found in small pools within Sphagnum bogs and channels within Papyrus associations close to open water.[2]
