This species of _Protea_ was collected early in 1921 by Mr. T. P.
Stokoe. At the time there was some doubt about its identity, and it was
provisionally placed under _P. speciosa_. Recently we received more and
better material from the same collector, and have no hesitation in
describing it as a species allied to _P. speciosa_. It differs from this
species in having shorter tufts of hairs at the apices of the involucral
bracts and the awns of the perianth are much longer and subequal. The
species belongs to a section of the genus _Speciosae_, which is
characterised by having the inner involucral bracts fringed with long
hairs or bearded. A comparison should be made with Plates 22, 76 and 84,
which illustrate examples of other sections of the genus.
The first specimens collected by Mr. Stokoe came from an isolated krantz
on a peak directly opposite Kogelberg on the land side, and subsequently
he found specimens also on high peaks facing Kogelberg, but on the
seaward side. It probably does not occur lower than an altitude of 3000
ft. The plant is a spreading bush about 6 ft. high (not so compact as
_P. speciosa_), and grows with such moisture-loving plants as _Mimetes
hottentotica_ and _M. splendens_. The young leaves have a fringe of
longish white hairs.
DESCRIPTION:--_Branches_ glabrous. _Leaves_ 7-9 cm. long, 3-4 cm. broad,
obovate, obovate-oblong, more rarely elliptic-lanceolate, rounded and
slightly emarginate at the apex, slightly narrowed to the base,
leathery, with reddish margins, quite glabrous. _Head_ sessile, 10-11
cm. long, 5·5 cm. in diameter. _Involucral bracts_ 9-10-seriate; the
outermost 1·5-2 cm. long, ovate-oblong, rounded at the apex, densely
silky pubescent, ciliate with white hairs with a small tuft of brown
hairs at the apex; the innermost 9 cm. long, 2·5 cm. broad above,
spathulate, silky pubescent, except at the base, with a fringe of
dark-brown hairs at the apex about 3 mm. long. _Receptacle_ 2 cm. long,
conical. _Perianth-sheath_ 5·5 cm. long, dilated and 3-keeled below,
glabrous; lip 1·2 cm. long, shortly but densely villous, 3-awned;
lateral awns 1·8 cm. long, linear, acuminate, shortly but densely
villous, tipped with a few brown hairs; median awn 1·5 cm. long,
otherwise similar. _Stamens_ all fertile; anthers 8 mm. long, linear,
with a pink linear apical gland. _Ovary_ covered with long, golden-brown
hairs; style 6 cm. long, subterete, slightly curved, very sparsely
pilose below; stigma 6 mm. long, linear; scarcely bent at junction with
style (Type in National Herb. Pretoria, No. 2632).
