Perennial. — Flowers in June and July. 
Root strong, running deep into the ground, subdivided and tufted 
at the crown. Stems solitary, upright, 8 or 10 inches high, round- 
ish, striated, panicled, with rarely more than one leaf, often naked. 
Leaves numerous, almost all radical, on longish petioles, kidney- 
shaped, pale green, somewhat wavy, with a more or less evident 
obtuse sinus (broad shallow notch) at the apex. Stipulas mem- 
branous. Panicle upright, twice as tall as the leaves, branched, 
with minute, egg-shaped, membranous bracteas at the base of each 
ramification. Flowers small, on slender, whorted, simple pedicels, 
which are thickest upwards. Anthers reddish. Germen nearly 
orbicular, compressed, notched, with 2, spreading, feathery styles. 
Fruit (fig. 4.), a nut, enclosed in an utricle, with a broad winged 
border, tipped with the styles situated in rather a deep notch ; and 
having at the base the 2 inner, pointed, segments of the perian- 
thium, not at all enlarged. See Hook. Brit. FI. 
The whole herb is powerfully and gratefully acid, with some 
astringency. Sir W. J. Hooker informs us, that this plant is the 
Donia sapida of Mr. Brown, (now Dr. Brown,) in the first edi- 
tion of Ross's Voyage to the Arctic Regions ; but it had been pre- 
viously named Oxyria (by Sir J. Hill). 
The plant from which the drawing for the accompanying plate 
was made, was kindly communicated to me by W. Bcrrer, Esq. 
This plant put up two flowering stems ; the first of which pro- 
duced flowers which were all perfect, or with both stamens and 
pistils ; the second, which flowered later than the first by ten days 
or a fortnight, produced only pistiliferous flowers. 
The Natural Order, Polygo'ne.t:, is composed of dicotyledon- 
ous, herbaceous, rarely shrubby, plants ; with sheathing stipulas ; 
and often monoecious or dioecious Jlowers. Their perianthium is 
inferior, monosepalous, and divided into from 4 to 6 segments, 
which are often in a double row. Their stamens are definite, in- 
serted in the bottom of the perianthium, with anthers opening 
longitudinally. The germen is superior, with 2 or more styles or 
sessile stigmas. The nut frequently triangular, with one erect seed, 
which contains, in a farinaceous, sometimes very thin albumen, a 
reversed and often unilateral embryo.
