small, 4-sepalous, 6-androus, semi-trigynous, in rather large heads which 
are two together and usually slightly stalked; the peduncles bearing 
stalked glands; bracteæ lanceolate, acute, with a pale white margin, and 
slightly rough and glandular. Fruit compressed, the faces convex, orbi- 
cular and acute, beautifully covered with minute reticulations, leaving 
deep pits between; the calyx is not agglutinated to the fruit, as is usual 
in this section. 
The two varieties are very closely connected, some specimens being almost 
exactly intermediate.

Stem procumbent, rooting, woody, the branches upright, glabrous. Leaves 
all stalked, cordate, acute, glabrous, fringed with minute spinous teeth,
