Male specimens of Aulax are only distinguishable by their foliage, and as the 
leaves of A. pallasia approach sometimes to one or the other of the two 
remaining species the determination of some of the males referred here to 
A, pallasia is perhaps open to doubt. ‘hese doubtful males are nearly all 
specimens without definite localisation. Burchell 8239 and 930 approach more 
than any others to A. encorifolia so far as the leaves (including those of the 
involucres) are concerned, but the structure of the involucral branches is clearly 
that of A. pallasia. One or the other of the lower marginal bracts of the 
involucral branches of A. pallasia may have a more or less perfect male flower in 
its axil. ;

Flowers dicecious, regular. Male flower: Perianth linear, straight 
or slightly incurved, with a somewhat thickened limb ; segments at 
length separated to the middle or nearly to the base, differentiated 
into limb and claw, spreading and recurved ; limb linear, oblong or 
elliptic. Anthers sessile at the base of the limb, oblong or linear ; 
connective sometimes shortly produced beyond the cells. Hypogynous 
scales 4, free, linear or filiform, or absent. Pistil rudimentary, 
consisting of a short slender style and a clavate entire or slightly 
bifid stigma. Female fower: Perianth more or less as in the 
male, but usually more deeply divided and the segments not so 
differentiated into limb and claw. Staminodes usually linear. 
Ovary ovoid, trigonous or compressed ; style usually slender and 
gradually widened towards the apex, usually persistent ; stigma 
terminal, oblique or lateral, entire or bifid, rarely 2-lobed. Ovule 
solitary, attached laterally or ascending from near the base. Fruit 
ovoid, transversely ellipsoid, trigonous or flattened and winged, 
sometimes emarginate. 
“Trees, shrubs, or decumbent under-shrubs ; leaves acicular, linear, lanceolate to 
obovate, entire, hardened at the apex into a blunt (rarely acute) callus, coriaceous, 
glabrous, pilose or clothed with adpressed silky silvery indumentum ; male 
flowers usually numerous, arranged in conical, globular or cylindric heads, each 
flower subtended by a bract ;~heads terminal, sessile or rarely pedunculate, some- 
times surrounded by an involucre of imbricate bracts within the upper leaves ; 
female flowers solitary, subtended by woody bracts aggregated in cone-like 
heads ; bracts erect or spreading, free or rarely partially united, usually truncate, 
younded or retuse at the apex, rarely subacute. 
Distris, Species about 62, endemic, many very imperfectly known, and 
described from specimens representing one sex only; the following key must 
therefore be regarded as provisional and artificial. 
*Leaves pubescent or tomentose with adpressed silky, 
silvery indumentum : ey 
Lower leaves 24 in. long or more, distinctly nerved ; 
male heads large, 14-24 in. indiam. —.... ... (1) argenteum.
