Perennial. — Flowers from June to September. 
Roots long, and stringy. Stems long, round, branching, leafy. 
Leaves roundish-heart-shaped, floating, very smooth, shining, and 
sometimes spotted above, purplish beneath, involute in the hud, 
their margins somewhat waved or repand-toothed ; on petioles 
which vary in length according to the depth of water in which they 
grow. Flowers axillary, on simple stalks (peduncles), which grow 
several together in a kind of sessile umbel. Corolla about an inch 
and a half in diameter, of a light yellow colour, with a darker 
radiating disk ; segments inversely egg-shaped, finely toothed or 
ciliated at the margin. Germen with 5 purplish glands at the 
base. Stigmas 5-cleft, notched, deciduous. Capsule (fig. 3.) egg- 
shaped, compressed. Seeds (figs. 6 & 7.) numerous, inversely 
egg-shaped, flattish, of a brownish colour, with a membranaceous 
ciliated margin. “ When the fructification is completed, the stem, 
which rose many feet in order to support the flower above the 
surface of the water, sinks considerably beneath it, and there re- 
mains till the next season of flowering, when it again resumes its 
annual task.” Times Telesc. for 1825, p. 198 ; & 1829, p. 275. 
Villarsia nymphaoides is a handsome plant, and well adapted 
for ornamenting large pieces of water. It is of easy cultivation ; 
and when it has once established itself it is difficult to eradicate it, 
as the stem sends out roots from every joint. It is a native of 
Denmark, Holland, Germany, Piedmont, and Siberia, as well as 
of England. 
In Japan the leaves are salted, and become a very glutinous sub- 
stance ; it is used in soups, boiled in which it becomes tender.
