Description

Vegetative characteristics

Nymphaea potamophila is an aquatic herb. The elliptic-sagittate, papery leaf blades of floating leaves are up to 20 cm long and 10 cm wide. [4] The leaf margin is entire and flat. [5] The adaxial surface is coloured in green with overlaying patterns of red variegation. The abaxial surface has a greenish base colour accompanied by dark red variegation, but also exhibits patterns of branched, rusty-brown striations. [4] The leaf structure is compact and the leaves are very thin (145.50 μm). This gives the leaves cold tolerance. [6] The glabrous, 3 mm wide petioles are very long and can exceed 4 m in length. [4]

Generative characteristics

The nocturnal floating flowers are connected to glabrous, 4 mm wide peduncles, which can exceed 4 m in length. [4] [7]

Cytology

The chloroplast genome size is 159,232 bp. [8] The chromosome count is unknown. [7]

Reproduction

Vegetative reproduction

Proliferating pseudanthia are not formed in this species. [5] [7]

Generative reproduction

High levels of both pollen viability and seed production are evident in Nymphaea potamophila. Sexual reproduction plays a significant role in this species. [4] [7]

Habitat

It can be found in the aquatic habitats of the Amazon Rainforest, [5] where it can grow along river margins in up to 4-5 m deep water. [7] [4]

Taxonomy

Type specimen

The type specimen was collected in Brazil by a team of scientists consisting of J. Ramos, C.D. Mota, L.A. Maia, and E. Soares on the 28th of June 1979. [4] [9]

Placement within Nymphaea

It is placed in Nymphaea subg. Hydrocallis. [8] [4]

Conservation

The conservation status of this species in Brazil has not yet been evaluated. [5]

Nymphaeaceae is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate and tropical climates around the world. The family contains five genera with about 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or rising from the surface. Leaves are oval and heart-shaped in Barclaya. Leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria and Euryale.

<i>Victoria</i> (plant) Genus of aquatic plants

Victoria or giant waterlily is a genus of aquatic herbs in the plant family Nymphaeaceae. Its leaves have a remarkable size: Victoria boliviana produces leaves up to 3.2 metres (10 ft) in width. The genus name was given in honour of Queen Victoria of the United Kingdom.

<i>Nymphaea</i> Genus of aquatic plants

Nymphaea is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution.

Plants of the genus are known commonly as water lilies, or waterlilies in the United Kingdom. The genus name is from the Greek νυμφαία, nymphaia and the Latin nymphaea, which means "water lily" and were inspired by the nymphs of Greek and Latin mythology.
