Nuphar ulvacea is a species of rhizomatous aquatic plant native to the US-American states Alabama and Florida. [2]
Nuphar ulvacea is an aquatic plant with stout, 2-5 cm wide rhizomes with 11-13 mm long, and 8-9 mm wide leaf scars. The petiolate, lanceolate, glabrous floating leaves with a blunt apex are 115-165 mm long, and 54-66 mm wide. The glabrous, terete, smooth petiole is 45-70 cm long, and 7 mm wide. The very thin submerged leaves are 23-28 cm long, and 7-10 wide. [3]
The flowers, supported by long peduncles, extend above the water surface. [4] They are 15-18 mm long, and 20-23 mm wide. They have six sepals. The subglobose, prominently ribbed fruit bears 3.5-4 mm long, and 2.5 mm wide seeds. [3]
Flowering occurs from Spring to early Autumn. [5]
It was first described as Nymphaea ulvacea G.S.Mill. & Standl. by Gerrit Smith Miller Jr. and Paul Carpenter Standley in 1912. Later, it was included in the genus Nuphar Sm. as Nuphar ulvacea (G.S.Mill. & Standl.) Standl. published by Paul Carpenter Standley in 1931. [2]
The type specimen was collected by A. H. Curtiss in a blackwater River near Milton, Florida, USA on the 14th of May 1898. [3]
The specific epithet ulvacea references the genus of algae Ulva , as the submerged leaves of Nuphar ulvacea resemble it. [3]
The NatureServe conservation status is T2 Imperiled [1] and its habitat is imperiled. [6]
It occurs in blackwater habitats, streams fed by springs, [5] [6] [3] and old, water-filled sand and gravel pits. [4]
