wing, and even that, although essentially terminal in Hakea and annular when present in Grevillea, is 
exceptional in Hakea platysperma, for instance, where the wing is almost of equal breadth all round the 
nucleus; but even there the texture and venation of the wing is that of Hakea, not of Grevillea, and the 
two genera are, with few exceptions, so natural that there are very few species that would not at once be 
referred to their right genus even without the fruit, especially as the wing of the seed can generally be 
traced into the ovule immediately after fecundation. The racemes are generally axillary and reduced to 
sessile clusters in Hakea, terminal and loose in Grevillea, but they are loose and elongated in the section 
of Grevilleoides of Hakea, and terminal in //. ru&cifolia and a few others; whilst the section Manglesia of 
Grevillea, as well as G. hakeoides and a few others, have the inflorescence of Hakea. The so-called 
involucres or imbricate bud scales enveloping the nascent inflorescences of Hakea, appear to be wanting in 
Grevillea, but they are also deficient in the section of Grevilleoides of Hakea, and are always so deciduous 
as to be generally absent from flowering specimens. The same variations of form in the perianth occur in 
the two genera, but in Hakea, the hairs or beard inside the tube of the many Grevilleas are always wanting 
and the ovary is always glabrous. Hakea has also the various modifications of the pistil of Grevillea, 
except the turgid style of the section Manglesia. The fruit is, in general, totally different in the two 
genera, and yet that of Grevillea yibbosa is certainly a near approacli to that of Hakea platysperma. 
Tiie determination of the species of Hakea generally requires the presence both of the 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. 
Botanical description. —Species, IT. saligna, Kniglit and Salisbury, Protect, \ 0 *, 
(1809). 
A tall, bushy shrub, quite glabrous or the young shoots slightly silky. 
Leaves usually lanceolate, obtuse, or with a short callous j>oint, tapering into a short petiole, 3 to 
G inches long, but sometimes oblong-elliptical anil 2 to 4 inches long, of a pale colour, 
veinless or obscurely and obliquely penniveined. 
Flowers small, in dense axillary clusters, the very short rhachis hirsute. 
Pedicels glabrous, filiform, about 3 lines long. 
Perianth glabrous, the tube scarcely 2 lines long, much revolute under the globular limb. 
Torus small. 
Gland small. 
Ovary nearly sessile ; style long, with a large lateral convex stigmatic disk. 
Fruit about 1 inch long, \ to f inch broad, with a short incurved beak, more or less rugose, and 
sometimes covered with large very prominent tubercles. 
Seed-winy shortly decurrent along the upper margin of the nucleus. 
The Queensland specimens, to which the name of 11. mimosoides specially applies, have 
longer leaves than most of the New South Wales ones, and F. Mueller’s have the fruits 
narrower and less tuberculate, but several New South Wales ones have the same long leaves, 
with the fruits unknown. Some of C. Stuart’s New England specimens have the leaves shorter 
and broader than usual. It will require, however, much more complete specimens to establish 
any definite varieties. (B.F1. v, 512.) 
This broad-leaved form is the common one in northern New South Wales (on 
the rivers as well as New England) and southern Queensland. This form is 
certainly H. jlorulenta, Meissner. 
Botanical Name. — Hakea, in honour of Baron Christian Lewis Hake. An 
interesting letter from Itobert Brown to Sir J. E. Smith will be found at page 112 
of my “ Sir Joseph Banks; the Father of Australia.” It would appear that Sir 
J. E. Smith’s feathers had been ruffled at the carving of Hakea out of Concilium,
