‘Stems about 1 foot high, branching below, sub-erect, woody at base, covered with 
long, white, soft, stellate hairs. Leaves 1-1} inches long, rarely 4 inch broad, green, 
chiefly hairy on the nerves of the lower surface, rarely sub-entire. Stipules longer 
than the petioles, quite like leaves, deeply cut. Calyx becoming bladdery in fruit. 
Filaments cruciform, with a very hairy, transverse tubercle above the middle ; anthers 
short. A remarkably distinct species, easily known by its stipules and inflated calyces.
