DESCRIPTION:--_Root_ thick, fleshy, simple or branched up to 30 mm. in
diam. and 20 cm. long. _Stem_ none, but one or more short branches
arising from the crown of the caudex. _Leaves_ crowded, 6-10 on a
branch, mostly erect and exposing the margin to the midday sun, cuneate,
gradually narrowed to the base, the apex straight or slightly rounded,
occasionally with a blunt mucro; the apical portion, and especially the
apical margin, closely covered with fine tubercles; on the wild plant
the entire leaf greyish-green, the margin reddish. _Flowers_ solitary on
each branch, sessile or subsessile, supported by 2 connate leaf-like
bracts. _Calyx_ turbiniform, 10-12 mm. long, the tube 11-13 mm. in diam.
at the mouth; sepals 5, of which 3 nearly equal, the 2 others narrower,
all triangular, 10 mm. long and wide, with a very narrow hyaline margin
and a thick umbo below the apex, finely tuberculate like the leaves,
grey, the margin red. _Petals_ uniseriate, narrow-lanceolate or
spathulate, 13-14 mm. long and 2-2·5 mm. wide in the middle, deep pink
on the inner side, paler on the outer side. _Stamens_ white, bending
inwards near the base and then erect, bearded at the bend. _Styles_
8-10, filiform, 6 mm. long, arising from the apex of the conical ovary.
Total diam. of open flower 20-25 mm., opening in the sun and closing
towards evening for several days.

This interesting _Leucospermum_ was collected by Mr. T. P. Stokoe in Jan
du Toit’s Kloof near Chavonnesberg, in the Western Province. Mr. Stokoe
states that only a few plants were observed growing in a belt of
_Proteaceae_. It is evidently very closely related to _L. tottum_, from
which it differs in having glabrous branches and non-ciliate involucral
bracts, and should be regarded as a glabrous variety of this species.
The genus _Leucospermum_ is closely related to _Protea_ (see plate 22)
but differs from that genus in having the limb of the posticous segment
divided and not completely fused. The well-known “Kreupelboom” (_L.
concospermum_) belongs to this genus.
