Nymphaea belophylla is a species of waterlily native to Bolivia, Brazil and Venezuela.[1]

Description

[edit]

Vegetative characteristics

[edit]

Nymphaea belophylla is an aquatic herb.[2] It has subglobose tubers, which are not stoloniferous.[3] The green, elliptic-sagittate leaves with an acute apex are up to 30 cm long and 11 cm wide.[4] The 4-5 mm wide, non-brittle, green petiole is glabrous.[3]

Generative characteristics

[edit]

The flowers of Nymphaea belophylla are floating and nocturnal.[2] The glabrous, green, non-brittle peduncle[3] is up to 5 mm wide.[4] In the original publication, the flowers are describes as inodorous.[3][4][5] In others, the floral fragrance described as sweet and fruity,[6] or as unpleasant and almond-like.[4] The smooth, pilose, ellipsoid seeds exhibit trichomes arranged in continuous longitudinal lines.[2] The seeds are 0.9 mm wide and 0.75 mm wide. The trichomes are 35-90 μm long.[4]

Cytology

[edit]

The chromosome count is not known.[4]

Reproduction

[edit]

Vegetative reproduction

[edit]

Stolons and proliferating pseudanthia are absent.[2][3]

Habitat

[edit]

In one instance, it has been found growing in flooded grassland savanna at water depths of 110 cm beneath Tabebuia aurea trees.[7] In another case, it was observed growing in floodplains at water depths of 1.5-2m among the grass species Oryza rufipogon and Paspalum wrightii.[6] In the Pantanal, where it can occur sympatrically with Nymphaea oxypetala,[3] it is found in floodplains and rivers.[8]

Taxonomy

[edit]

It was first described by Trickett in 1971 based on plant material cultivated at the Royal Botanic Gardens, Kew. The plants had been introduced to cultivation by Amanda Bleher from a specimen collected in Guaporé River, Brazil.[3][5][9]

Type specimen

[edit]

The type locality is the Río Guaporé. It seemed that the type material had gone missing,[10][6] however the holotype was later found again. The isotype could still not be located.[3]

Placement within Nymphaea

[edit]

It is placed in Nymphaea subg. Hydrocallis.[7][4]

Etymology

[edit]

The species name is derived from the Greek βέλος meaning arrow or dart,[5] and -phylla referring to the leaves. It references the strongly pointed, arrow-shaped leaves.
