1. C. dioicum, Radlk. in Abhandl. Naturw. Ver. Bremen, viii. 

 ±12. A much-branched shrub with greyish bark ; leafy branches slender, 

 reaching 6-7 in. in length, bearing a dense yellowish-brown pubescence. 

 Leaves ovate-elliptic, obtuse with shortly mucronate apex and rounded 

 base, generally between 0-9 lin. long, 2-J--5 lin. broad, tomentose like 

 the stem; petiole slender, tomentose, lf-2 lin. long. Flowers small, 

 solitary or few in subsessile umbelliform axillary cymes. Bracts minute, 

 linear, subacute, bearing, as do also the slender pedicels (about 3 lin. 

 long), the characteristic pubescence. Sepals 5, subequal, obovate-elliptic, 

 obtuse, barely 1|- lin. long in the male flower, pubescent on the back, the 

 two inner somewhat smaller and ovate; accrescent in fruit. Corolla 

 shortly funnel-shaped, 3 lin. long, whitish (" lactea "), deeply 5-fid ; 

 lobes rather narrowly obovate, obtuse, miclpetaline areas densely hairy. 

 Stamens a little shorter than the corolla ; filaments filiform, tapering, 

 becoming broader, thickened and shortly hairy at the base ; anthers 

 oblong, | lin. long, replaced in the female flower by flattened sterile 

 structures. Ovary (small in the male) surrounded by a ring-like disc, 

 glabrous except for a few scattered hairs at the apex. Styles connate 

 at the base ; stigmas hippocrepiform. Capsule globose, about 1^ lin. in 

 diam., glabrous, 2-celled ; cells 1 -seeded by abortion ; pericarp thin, 

 brittle ; seeds (immature) black, glabrous. — Hallier f . in Engl. Jahrb.
