Annual. — Flowers in July. 
Root of many, loner, white, simple fibres. Stem none. Leaves 
all radical, awl-shaped, spreading, smooth, (as is the whole plant,) 
from 1 to 2 inches long. Scape ( flower-stalk ) upright, somewhat 
zigzag, from 2 to 4 inches high ; usually wholly under water. 
Flowers few, white, very minute, racemose ; pedicels alternate, 
slender, single-flowered. Pouch (fig. 7.) upright, oval, smooth, 
tipped with the sessile roundish stigma ; valves (see fig 8.) convex, 
tumid Seeds (see figs. 8 & 9.) oval, smooth. Embryo , see fig. 10.) 
curved above the base of its long, strap-shaped cotyledons. 
It is a native of other colder parts of Europe besides Britain, as 
Lapland, Sweden, Norway, Germany, & c. It is singular that this 
curious little plant should blossom several feet below the surface of 
the water. According to Sir J. E. Smith and Sir W. J. Hooker, 
the flowers always remain entirely under that element, even during 
the time they are expanded ; thus forming a remarkable deviation 
from the general rule, for water-plants almost invariably elevate 
their flowers above the water before the petals open, in order that 
fertilization may take place in air. That it does sometimes flower 
out of the water, appears from the following observations of the 
Rev. Hugh Davies. “ In the dry summer of 1798,” says Mr. 
Davies, “ as I walked the bed of a lake called Llyn Llywenan,in 
the parish of Bodedern, [Anglesea,] whence the water had retired 
about two months before, I, unexpectedly, discovered this plant in 
great abundance. Notwithstanding its appearance was very differ- 
ent from what I had been used to see in the Arvonian Alpine Lakes, 
where it always blossoms and seeds at the bottom, under water of 
considerable depth, yet it did not seem to regret the privation ; the 
foliage was spread, the leaves somewhat reclining, and the flowering 
stems procumbent ; the calyx and corolla were fully expanded ; 
the petals, which are white, and of an obovate form, were horizon- 
tal, the seed-vessels and seed quite perfected ; and, on the whole, 
it seemed to indicate a quite different plant.” Welsh Botanology ,
