Adumbr. Radices cylindricae, saepius fibrillis patentibus, plumosae, petiolares numerosae. Folia, petiolo pollicari proprio a cyma dissita, 3-6" longa et lata, hinc minora, auriculis saepius subapproximatis parallelis, nervis obsoletis palmatis, supra asperiuscula, subtus glandulis minutis ipsarum diametro quater distantibus obsita, demum aspera et lacunosa. Flores circiter 12. Sepala 5 ovato-lanceolata, capsula 2-3plo breviora. Corollae diam. circiter 9"': loborum discus juxta cristam nudus: glandulae et epipetalae et ovarium cingentes flavae. Ovarium subglobosum. Capsula mono-disperma!, seminibus raphe conspicus notatis.

Outline. Roots cylindrical, rather often with evident fibers, downy, petioles numerous. Leaves, emitted from the cyme with a single petiole of 1 in [2.5 cm], 3-6 in [7-15 cm] long and wide, or less, rather often with subapproximate, parallel auricles, with faint palmate veins, rather rough above, underneath with tiny glands, [ipsarum diametro quater distantibus obsita], at length rough and lacunose. Flowers about 12. Sepals 5, ovate-lanceolate, 2-3 times shorter than the capsule. Corolla diameter around 9 lin [19 mm]: disc of the lobes bare, next to the crest: glands both epipetalous and yellow, surrounding the ovary. Ovary subglobose. Capsule one- or two-seeded, seeds marked by a conspicuous seam.

Antara-jamara of the Telingas.
Roots annual, fibrous.
Leaves radical, petioled, hearted, with large, rounded, posterior lobes: lobes overlap a little; margins waved, smooth, above green, with a purplish tinge; size very various, the larger are from four to six inches long.
Petiole round, length various; on the upper side, about two inches below the leaf, there are tubercles which bear flowers, other leaves, and roots; the old leaf and the parent petiole decaying, leaves a new plant, each petiole in succession doing the same.
Peduncles many, from the above mentioned tubercles of the petiole, one-flower'd, and of length sufficient to raise the flowers a little above the water, when expanded; afterwards they bend under water, and there ripen their seeds.
Flowers pure white, about an inch in diameter.
Calyx five-leaved: leaflets broad-lanced, permanent.
Corol one-petal'd: divisions of the border oblong, expanding, with broad membranaceous, waved, curl'd, ragged, margins; down the middle of each there runs a ridge or wing, exactly similar to half of one of the divisions: no hair on the flowers.
Nectary triple: exterior: white, ramous filaments, crown the mouth of the tube of the corol, as in Nerium; middle: five beautiful yellow, glandulous bodies, nearly fill the mouth of the tube, standing alternately with the filaments; interior: five hairy yellow bodies, surround the base of the germ.
Filaments inserted into the tube of the corol near its base.
Anthers oval.
Style short.
Stigma two-cleft: segments large and lobed.
Seeds a little compress'd, rugged.
Receptacles opposite, running down the inside of the capsule.
A native of tanks, or pools of fresh water, where it floats, often not reaching the bottom with its roots. Flowering time the wet and cold season.
