Calyx-tube very short ; segments 5-G, lanceolate or oblong. 

 Corolla-tube campanulate or shortly funnel-shaped, with 5-G peltate 

 tufts of hairs above the middle ; lobes 5-G, oblong, valvate, the broad 

 induplicate edges fimbriate or entire. Stamens 5-C, inserted at or 

 below the corolla-sinuses ; filaments short ; anthers versatile. Hypo- 

 gynous glands minute. Ovary 1-celled ; placentas parietal. Style 

 short or long ; stigmas 2-lobed. Capsule globose, ovoid or oblong, in- 

 del^iscent or buisting it*regularly. Seeds few or many, smooth or 

 tuberculate, sometimes subcarinate. — Aquatic herbs. Stems erect or 

 runner -like with alternate or subopposite leaves, or resembling petioles, 

 and described below as false petioles. Leaves orbicular, elliptic or 

 ovate, deeply notched or rarely entire at the base, entire, crenate or 

 toothed at the margin. Flowers solitary, in pairs or clusters at the 

 nodes, or on the apparent petiole close to or at a little distance below 

 the leaf -blade. Pedicels fascicled or single. Flowers yellow or white, 

 heterostyled. 



Species several, widely spread throngh the tropical and temperate regions of both 

 hemispheres. 



Many of the species of this genus, being much alike, require revision from care- 

 fully prepared descriptions or notes made from living specimens. The characters 

 afforded by the corolla are exceedingly difficult to observe in the dried state. The 

 seeds, however, of the various species are very distinct when compaicd side by 

 side, although it is somewhat difficult to state the differences in words. Other 

 characters may be found in the pedicels and number of flowers in a cluster. —
