Leucospermum.} PROTEACE (Phillips & Stapf). 611 
limbs soon free, deflexed or inflexed on the revolute tips of the 
claws. Stamens 4; anthers oblong to ovate, sessile or subsessile, 
inserted at the base of the limb ; connective always very marked 
on the back of the anther, sometimes produced into a small point. 
Hypogynous scales 4, linear or subulate. Ovary sessile, pubescent, 
surrounded by a basal ring of hairs; style filiform or subulate, 
straight or nearly so, subpersistent ; stigma conical, ovoid, obliquely 
turbinate or cylindrical, large or small, epapillose. Ovule 1, laterally 
attached. Fruit a smooth, whitish, often shining nut with a crusta- 
ceous pericarp. Seed solitary. 
Erect or sometimes procumbent shrubs ; leaves usually very crowded, entire or 
toothed at the apex, coriaceous, like the stems usually with a fine dense whitish 
or greyish covering of minute curled hairs and sometimes an additional indu- 
mentum of copious or scanty long spreading hairs, or sooner or later glabrous ; 
flowers in terminal, or by overtopping pseudolateral, heads ; heads solitary or in 
clusters of 2-8, rarely more, shortly peduncled or sessile, bracteate, all the bracts 
of the head fertile or usually the outer barren, forming a more or leas distinct 
involucre, the fertile bracts distributed over a cylindric, conical or flat receptacle, 
like the barren ones persistent and often at length indurated, nearly always very 
densely tomentose on the back; perianth more or less hairy, usually yellow 
(rarely red) or reddish upwards ; styles yellow ; stigmas often red. 
Distris. About 32 species in extratropical South Africa, mostly in the coast 
region, one extending into Rhodesia.

Section 1. ConocarpopENDRoN. Heads large, including the styles 24 
(rarely 2)-3 in. long, with or without a distinct involucre of barren 
bracts ; receptacle cylindrical, much longer than wide (excepting 12, 
premorsum); fertile bracts persistent, more or less indurated; the 
adaxial and lateral perianth-claws permanently united into a sheath, 
or flattened-out and revolute in the upper part ; abaxial claw adhering 
long to the top of the sheath, otherwise free ; limbs reflexed or inflexed ; 
styles 14-3 in. long, tapering and markedly quadrangular (or sometimes 
sub-8-angular) upward; stigma various. Small, mostly erect shrubs, 
rarely attaining to 6-10 ft.
