Nuphar ozarkana is a species of aquatic plant native to the US-American states Arkansas, Missouri, and Oklahoma. [1]
Nuphar ozarkana is an aquatic species with a slender rhizome. The leaves mostly float, but they can also be erect. The petiolate, orbicular to oblong, smooth, glabrous, yellowish green leaves are 12-20 cm long, and 7-19 cm wide. The terete, glabrous petioles are 3-11 mm wide. [2]
The pedunculate, yellow, 30 mm wide flowers have stout, glabrous peduncles. The thin, glabrous sepals are green, but display yellow colouration towards the apex. The smooth, subglobose, 15-25 mm long, and 14-20 mm wide fruit bears 15-30 ovoid, shiny, pale brown 5 mm long, and 3.5 mm wide seeds. [2] The flowers are not fragrant. [3]
This species has an outstandingly low number of seeds per fruit. [2]
It was first described as Nymphaea ozarkana 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 ozarkana (G.S.Mill. & Standl.) Standl. published by Paul Carpenter Standley in 1931. [1]
The type specimen was collected by Otto M. Smith along White River in Southern Missouri in August 1910. [2]
The specific epithet ozarkana references the Ozarks region. [4]
It is pollinated by Lasioglossum nelumbonis , Lasioglossum bruneri , and Augochlora pura , which together make up 97% of all floral visitors. [3]
