The typical form is one of the most easily recognized species of the genus, from 
the prominent characters of the numerous rigid simple purplish-black stems and small 
uniform deeply-toothed leaves.

—Stems numerous from a hard woody rootstock, 2-6in. high, decum-

a short uniform pubescence. Leaves opposite or the upper alternate, 
crowded, }—$ in. long, linear-oblong, obtuse or apiculate, coarsely toothed,

This comes nearest to H. melanocaulon, trom which it is distinguished by its 
smaller size, paler colour, uniform pubescence, and especially by the short curved Cap: 
sules, which are abruptly narrowed towards the tip. Mr. Petrie’s var. pubens appears 
to be distinct, but it is described from very scanty material.

Stems very numerous from a hard and woody base, much branched 
below, 3-8 in. high, shortly decumbent at the base, erect strict and wiry 
above, dark purplish-black, bifariously pubescent. Leaves small, opposite 
or the upper ones alternate, 4-1 in. long, oblong or ovate-oblong or ovate- 
orbicular, obtuse, sessile or very shortly petioled, obscurely denticulate or 
quite entire, glabrous, coriaceous. Flowers few towards the tips of the
