General:
Perennial herb from a rhizome; stems decumbent to trailing and rooting at the nodes, somewhat hairy, 5-30 cm long.

Flowers:
Inflorescence a dense, globe-shaped, long-stalked head of numerous pea-like flowers, the heads 8-12 mm wide at flowering time but becoming larger, fuzzy and reddish-brown with age; involucral bracts tiny; corollas purple to pink, 4-6 mm long; calyces coarse-hairy, at first from 2/3 as long as to equalling the corollas, quickly exceeding and hiding them, the tube inflated and net-veined in age so that the head looks like a mass of veined bladders, the teeth linear to bristle-like.
