Description

edit

Vegetative characteristics

edit

Nymphaea kimberleyensis has swollen, 12 cm long rhizomes. The leaves have a dentate margin.[2]

Generative characteristics

edit

The sepals are 9–18.5 cm long. The 9.5-14.5 cm long petals[3] are blue, but display white colouration at the base. The androecium consists of 200 stamens. The gynoecium consists of 15-20 carpels. The glabrous seeds have only been observed in an immature state.[2] The fruit does not develop to maturity.[3]

Reproduction

edit

Generative reproduction

edit

Flowering occurs from March to June. Only immature seeds have been observed.[2] The fruit fails to reach full maturity.[3]

Taxonomy

edit

Publication

edit

It was first described by Surrey Wilfrid Laurance Jacobs as Nymphaea immutabilis subsp. kimberleyensis S.W.L.Jacobs in 1992 . Later, it was elevated to a separate species Nymphaea kimberleyensis (S.W.L.Jacobs) S.W.L.Jacobs & Hellq. by Surrey Wilfrid Laurance Jacobs and Carl Barre Hellquist in 2011.[1]

Type specimen

edit

The type specimen was collected by S. Jacobs, and P. Wilson in the Kimberly region of Western Australia on the 23rd of May 1988.[2][3]

Placement within Nymphaea

edit

It is placed in Nymphaea subgenus Anecphya.[3][4][5]

Natural hybridisation

edit

Nymphaea kimberleyensis may be of hybrid origin.[3]

Etymology

edit

The specific epithet kimberleyensis indicates this species origin in Kimberly, Australia.[6][7]

Conservation

edit

It is a rare species.[2]

Ecology

edit

Habitat

edit
