50 NATIVE HONEYSUCKLES OR BANKSIAS. 
and gorgeous in flowers occur. The genus disappears in Central 
Australia, although all conditions for its occurrence exist there, 
reappears in North Australia and crosses over to New Guinea. 
Proteacese are more extensively still represented in Victoria 
by the well known genera Grevillea and Hakea, the former 
dedicated to the Right Honorable Charl. Franc. Greville, of 
Paddington, the latter genus named in honor of Baron Hake, of 
Hanover, both having been alike patrons of horticulture at the end 
of the last century. It is easy to distinguish these genera from 
Banksia ; the segments of the flowers are usually of unequal 
length and revolute while in bud, never crowded on a woody axis ; 
the fruitlets become not consolidated and contain no septum. 
The distinctions between Grevillea and Hakea are faint, several 
species mediating the transit from one genus to the other. In 
most Grevilleas however the fruitlets are not of the woody 
hardness of those of all the Hakeas, while the membrane, which 
terminates the seeds of Hakeas in nearly all instances, is either 
absent or equally surrounding the seeds of Grevilleas, and never 
black as in Hakeas ; thus the nucleus of the winged seeds of the 
Hakeas is nearly always eccentric. Moreover the flowers of 
Grevilleas are in most instances terminal, those of the Hakeas 
mostly axillary. Many species of either genus are highly orna- 
mental, while the form of the leaves of some is very odd ; their 
foliage is always thick, often rigid, not rarely pungent. These 
plants form a prominent feature in our scrub-vegetation ; none of 
the Victorian species is truly arborescent, but in the tropic and 
subtropic regions of Australia they attain to arboreous growth ; 
one of the most noble of these trees being Grevillea robusta of the 
northern coast-forests of New South Wales and the southern 
woodlands of Queensland, one of our most eligible among avenue- 
trees, and now chiefly through the writer’s actions one of the 
most accessible garden-species for local studies also. To demon- 
strate characteristics the description is given of one of the few 
widely distributed Victorian species, which was discovered in 
West Australia by Baron Von Huegel in 1833 : 
Grevillea Huegelii.—Leaves pinnately cleft into 3-9 segments, 
glabrous above, doubly grooved and somewhat silky beneath; all
