Perennial, two to four feet high. Stem short, woody. 
Branches longish, four-sided, opposite, harshly pubescent. 
Leaves opposite, on longish petioles, broadly cordate, blunt 
with coarse bluntish serratures, harshly strigose with short 
straight or hooked hairs. Racemes terminal, or from the 
forkings of the upper branches, long, hispid. Flowers num- 
erous, very shortly pedicelled, at length remote at the base 
of the raceme, on account of its elongating. Bractea solitary 
to each flower. Calyx tubular, and somewhat gibbous, 5- 
angled, 5-toothed, clothed with short rigid hooked hairs, 
after flowering inflated, dry, persistent and enclosing the 
fruit. Corolla white, hypocrateriform: tube cylindrical, 
longer than the calyx, slightly curved, twisted near the 
summit; limb 5-partite, the segments equal, obovate. Stamens 
4, inserted into about the middle of the tube of the corolla, 
two of them curved, and twice as long as the others: fila- 
ments hairy : anthers roundish-ovate, 2-celled, approximating 
in pairs. Ovary superior, 4-celled; ovules solitary in each 
cell, and attached to the base. Style filiform, curved and 
clavate at the apex. Fruit nut-like, entirely enclosed within 
the persistent calyx, obcordate, compressed, 2-valved, gib- 
bous and furnished with numerous prickles at the back of
