Hake a.] 
CXI. PROTEACEiE. 
134-5 ■ 
more frequently placed near the upper margin and covering about half only or 
rather more, the remainder of the valve a hard woody mass. — Shrubs or rarely 
small trees. Leaves alternate, very diversified in shape, flat or terete, the- 
margins rarely recurved, and the two surfaces usually similar and equally veined. 
Flowers in pairs along the rhachis of a short and dense raceme or cluster or 
rarely in a longer raceme ; the clusters or racemes sessile in the axils or rarely 
also terminal or in a very few species all terminal. Indumentum as in Grevillea, 
consisting of closely appressed hairs attached by the centre, rarely of erect or 
spreading hairs. 
The genus is limited to Australia. 
The determination of the species of Hakea generally requires the presence both of flowers and 
fruit. Species, especially amongst the terete-leaved ones, with scarcely distinguishable flowers* 
and leaves, have sometimes very different fruits, whilst closely similar fruits have occasionally 
very different flowers and leaves. I have found the flowers chiefly available for sectional, the 
fruits for specific distinction. The dorsal protuberances on the fruit-valves of some species 
usually called spurs, appear to me to be more appropriately termed horns, as they occur always 
close to the apex not to the base of the valve. — Benth.
