Resembling the leaves of Rumex sanguineus, in size as well as form. 
R. Syn. 49. Stem very short, ending in oblong spear-shaped leaves, 
very entire, waved at the edge, rounded at the end, furnished with a mid¬ 
rib which sends off lateral alternate veins ; from three inches to a foot in 
length, and from three quarters to two inches in breadth ; pellucid, pale 
red purple. Gmelin Fuc. 185. Fructifications roundish, on fruit-stalks, 
blackish red, on the sides of the branches and ribs, of the size of rape 
seed. Huds. n. 3. Stem very short, woody, branched. Leaves mid- 
ribbed, oblong, blunt, but six inches long and one and a half inch broad, 
pellucid and thin as gold-beaters’ skin ; red, often with cross bars or 
stripes of a dull pinky yellow. Stackhouse.

F . sinuo'sus. Leaves membranaceous, oblong, waved, indented: stalk 
cylindrical; branched. 
{Turn. Hist. 35. E.)— Stackh. 7—{E. Bot. 822. E.) 
Stem cylindrical, woody, branched, garnished with leaves of various sizes. 
Leaves on leaf-stalks, mid-ribbed, veined, scolloped and indented, often 
fringed; thin, pellucid; colour pale pink, with tints of green and olive. 
The mid-rib of the larger leaves sends out smaller leaves. Stackhouse. 
Fructifications, small red oblong substances, tapering down into fruit- 
stalks, placed on the stem or on the edges of the leaves. Within these 
substances, which in the microscope appear like processes issuing from 
the leaves, small red granulations may be seen.

About two or three inches high, membranaceous, extremely thin, bright 
red. Fructifications— Male, vesicles the size of mustard seed, dark red, 
placed on the nerve near the extremity of the leaves.—Female, numerous 
very minute grains scattered near the nerve on each side the leaf. It is 
possible that these red vesicles may be real capsules, and that the gra¬ 
nulated appearance may proceed from the capsules having burst and dis¬ 
charged their seeds. Woodward. Linn. Tr. ii. 30. One single globular 
vesicle in which minute grains may sometimes be found, appears to be 
the complement to each leaf, arising from the nerve which passes 
through the centre of these globules. Major Velley. (Mr. Turner has 
since proved that the globules on the mid-rib are capsules, from which 
the seeds are discharged with an elastic force, and then adhere to the
