PROTEACE# (Stapf). 503 
mostly coriaceous, exstipulate. Flowers solitary or in pairs in the axils of per- 
sistent or deciduous bracts, arranged in racemes, umbels, spikes or small or 
large heads, the latter often involucrate. 
Distrip. Over 50 genera with nearly 1000 species, of which 14 genera in- 
habit South Africa, a few of these extending into Tropical Africa, the remainder 
mostly in Australia, few in the Indo-Malayan region, the Pacific Islands and 
South America, 
Tribe 1. PrERson1r®.—Flowers solitary in the axils of leaves or in bracteate 
racemes or spikes. Perianth actinomorphic, with the segments separating 
as the flower opens, or soon afterwards. Filaments free or adnate to the 
perianth-segments at the base only or up to below the limb. Ovules 2 or 1, 
rarely more, pendulous and orthotropous, rarely laterally attached and 
amphitropous. Fruit indehiscent. Cotyledons thick, unequal, 2 or more. 
I. Brabeium.—Flowers hermaphrodite or polygamous in dense axillary spike- 
like racemes. Filaments attached to the base of the perianth-segments. 
Ovary sessile, woolly ; ovules 2, pendulous. Fruit a drupe with a 
corky exocarp and a woody endocarp. Leaves verticillate, serrate. 
Tribe 2.—Prorerm.—Flowers solitary in the axils of bracts, usually in heads, 
more rarely in spikes or racemes. Perianth actinomorphic or more or less 
zygomorphic, with all the segments more or less deeply separating or with 
only one detaching itself from the remainder of the perianth. Anthers 
sessile or subsessile at the base of the limb. Ovule 1, laterally attached or 
ascending, amphitropous. Fruit a dry nut, sometimes winged. 
* Flowers diwcious, actinomorphic. Leaves entire. 
II. Aulax.—Male flowers in spike-like racemes ; female flowers in involucrate 
heads ; involucre made up of whorls of flattened dorsally foliate and 
laterally bracteate branchlets, resembling pectinate bracts ; flowers 
solitary on the inner side of the branchlets and in spirals on a central 
axis or only on the latter. Nuts laid bare. 
III. Leucadendron.— Male and female flowers in bracteate heads ; bracts per- 
sistent, the outer often forming an involucre, accrescent and 
indurated in the female heads which on maturity become strobili- 
form. Nuts hidden within the bracts, more or less compressed, 
sometimes winged. 
** Flowers hermaphrodite, more or less zygomorphic, at least on opening. 
Inflorescence capitate or spicate. Leaves entire. 
+ Flowers capitate. 
IV. Protea,—Anticous (abaxial) perianth-segment entirely separating from the 
others, which remain fused into a sheath widened at the base and 
a 3-toothed or 3-awned lip. 
V. Leucospermum.—Anticous (abaxial) perianth-segment separating more or 
less between the base and the limb, never quite free ; limb recurved 
in the open flower. 
++ Flowers spicate. 
VI. Faurea.—Perianth splitting anticously (abaxially) to the base or 
almost so. 
*** Flowers hermaphrodite, actinomorphic or slightly zygomorphic (Spatalla) ; 
perianth-segments in the open flower cohering at the base only, 
Inflorescence capitate. Leaves entire or variously divided. 
+ Flowers in typically many-flowered, or sometimes by reduction few- 
. flowered, terminal or axillary heads. 
t Leaves undivided. 
VII. Mimetes.—Heads medium-sized, aggregated and partly hidden in the 
axils of the upper leaves, 
VIII. Orothamnus.— Heads large, much exserted from the axils of the upper
