Nymphaea tenuinervia is a species of waterlily native to Colombia, Guyana and Brazil. [1]
Nymphaea tenuinervia is an aquatic herb. [2] The ovoid rhizome is stoloniferous throughout the vegetative period. [3] The heart-shaped to egg-shaped leaves have a firm texture and entire margins. [4] The leaf blade is 21 cm long and 19 cm wide. [3] The abaxial leaf surface features elongated round, small, black spots directed along their longitudinal axis toward the centre of the leaf blade. The petiole bears downward-facing trichomes towards its upper end. [4] The leaf bears characteristic bifurcated (Y-shaped) trichosclereids in the mesophyll layer of the leaf. [5] [6]
Nymphaea tenuinervia has protogynous flowers with nocturnal anthesis. [8] The floral fragrance has been described as solvent-like. It is primarily composed of anisole, but also significantly smaller amounts of (methoxymethyl)benzene and butyl acetate. [7] The ovoid, granulose, pilose seeds feature trichomes arranged in continuous longitudinal lines. [2]
The diploid chromosome count is 2n = 20. [3] It has 8 large and 12 smaller chromosomes. [9]
In most populations vegetative reproduction through stolons plays a significant role in reproduction. [3] Proliferating pseudanthia are absent. [2]
Autogamy was not observed in this species, therefore a reliance on out-crossing for generative reproduction is likely. [3] [8]
In Brasil, it occurs in the Amazon rainforest, the central Brazilian savanna, and the Atlantic rainforest as aquatic vegetation. [2]
The type specimen was collected near Juazeiro in the St. Francisco river of Bahia, Brazil in April 1819. [10] [11] [3]
It is a member of Nymphaea subg. Hydrocallis. [3] [7]
In the original description it was first named Nymphaea tenuinervia. However, in other parts of the publication it is spelled as Nymphaea tenerinervia. [3] [10] Nymphaea tenerinervia Casp. is an orthographical variant of Nymphaea tenuinervia Casp. [12]
The specific epithet tenuinervia is composed of two parts. The first part tenui- means thin or slender, and -nervia means veins or nerves. Together it means fine-nerved. [13] [14]
Scarabeid beetles are thought to be pollinators of Nymphaea tenuinervia. [8]
