Ottelia (from a name in Malabar). Hydrocharitaceae. Perhaps two dozen fresh-water herbs of the tropics and subtropics of both hemispheres, some of which may be useful as aquatics: Lvs. both submerged and floating; the latter with long petioles, the blades lanceolate, ovate or cordate: scape elongated, bearing a fl. in a winged spathe; calyx 3-lobed; petals 3, yellow or white, much longer than calyx-lobes; stamens 6-10 or more, bearing erect anthers: fr. 6-valved, inclosed in the spathe. O. alismoides, Pers. (Stratiotes alismoides, Linn.) is of wide distribution. Afr. to Austral.: perenennial, the Lvs. arising from the base on long 3-angled petioles; blades broadly cordate, or rounded, obtuse, 2-6 in. or even more long or broad, 7-11-nerved: fls. white, the petals broadly ovate and 1 in. long. B.M. 1201 (as Damasonium indicum). G.W. 14, p. 658.—The plants are said to be eaten as pot-herbs by natives.
