Descr. Plant eight to ten inches high, somewhat 
shrubby at the base, above herbaceous, much and dichoto- 
mously branched, four-sided, hispid with spreading hairs. 
Leaves opposite, rarely, at the dichotomies, quatenate, 
ovate, acute, spreading, serrated, hispid and ciliated, three 
to five-nerved, paler, sometimes reddish beneath: upper 
leaves gradually smaller, so that the plant terminates in a 
somewhat leafy panicle. Flowers solitary, terminal, upon 
a short hispid pedicel. Calyx hispid: tube ovate, the limb 
of four reflexed linear-oblong segments; there are no 
scales alternating with the segments, but a bristle there 
situated is generally larger than the rest: within at the 
mouth are eight small coloured glands. Petals four, obo- 
vate, approaching to round, of a pale rose-colour, fringed 
at the apex. Stamens eight, exserted, nearly erect, equal. 
Anther oblong, acuminate, yellow, with two gibbosities at 
the base. Germen free, ovate, hispid at the apex. Style 
filiform, exserted.
