GREVILLEA LAVANDULACEA. 
GREVILLEA LAVANDULACEA. 
Nat. Order. — Proteaceje. 
Generic Character. — Grevillea, R. Brown. — Perigone 
four-leaved or four-parted, irregular, the lobes somewhat 
spathulate, recurred, revolute. Anthers (our, immersed in the 
concave apices of the lobes of the perigone. Hypogynoas gland 
solitary, halved. Ovary sessile or stalked ; one-celled, with 
two ovules. Style ascending; stiff ma oblique and depressed, or 
subvertical and conical. Follicle leathery or woody, one- 
celled, two-seeded. Seeds margined, or with a short wing at 
the summit. — Shrubs or trees, occurring throughout New Hol- 
land, often with pubescence, which, when present, consists of 
hairs fixed by their middle ; leaves alternate, undivided, or 
pinnatifid and bipinnatifid ; cutaneous glands attached by their 
bases, or, more rarely, all round ; spikes sometimes elongated 
and racemose, sometimes abbreviated and corymbose, or fasci- 
culiform ; pedicels in pairs, or rarely several together, the pairs 
or the fascicles subtended by a single bract ; perigone reddish 
or yellow ; in some cases inserted obliquely. — {Endlicher Gen. 
Plant., 2143.) 
Grevillea lavandulacea, Schlcchtendahl. — Lavender-like 
Grevillea.— Clothed all over with somewhat adpressed hoary 
hairs; leaves linear-oblong, rather acute, mucronate or cuspi- 
date, the margins slightly or tightly revolute {hence they are 
commonly terete), finally punctate, scabrous on the upper side, 
whitish hoary beneath ; racemes terminal, few-flowered, erect; 
style rather hairy, almost twice as long as the calyx ; stigma 
lateral oblique, concave, glabrous.

G. lavandulacea, Schlcchtendahl, in Lintixca, xx. 586. 
BESCRLPTION. — A stiff erect shrub, •with diverging branches terminating in inflorescence, 
clothed with somewhat adpressed hairs. The leaves are scattered, linear-oblong, about 
three quarters of an inch long, the margins truly revolute, not angularly folded ; the lower face 
whitish and silky, the upper green, finally punctate, scabrous, the point armed with a niucro. 
Flowers collected in tufts at the ends of the branches, stalked, the peduncles short and hairy ; 
the perianth hairy, half an inch long, rose-coloured ; ovary slightly stalked, hairy ; style (with 
the ovary) one inch long, attenuated gradually to the summit, where it again expands into a 
spoon-shaped stigma, rendered lateral by the curvature of the summit of the style. — A. H. 
Histoky, &c. — This very pretty greenhouse shrub was raised by Messrs. Henderson of 
the Pine Apple Nursery, Edgeware Eoad, from seeds transmitted from the Swan River settle- 
ment by Mr. Drummond. It flowered with them very freely during the past spring, and was at 
that time exhibited, and much admired, at one of the ordinary meetings of the Horticultural 
Society. Our drawing was made from this plant. Its general aspect is that of G. rosmarinifolia, 
another very pretty species, now getting comparatively rare ; hut it is abundantly distinct, and 
much more elegant. — M. 
Cuxttoe. — Like most of the other species, this plant is of easy cultivation; and the 
following treatment will suit it well : — Presuming you have an established plant, take it 
early in the season, February or March, and shift it into a larger pot, into soil consisting 
of turfy peat, leaf-mould, and nice mellow loam, in about equal proportions, liberally inter- 
mixing the same with potsherds broken small, and gritty sand. Drain the pot thoroughly, 
and make the soil in potting tolerably fine. If it is wished to grow the plant rapidly, the best 
place to put it in will he a cool stove or warm greenhouse, supplying it sufficiently at the roots 
with water, and sprinkling it daily in warm weather over the foliage. As the plant progresses, 
stop the strongest shoots to make them branch, and pot as frequently as is necessary until you 
get a large plant. During the autumn, the plant will be best in the open air; and 
through August and September, to insure its blooming, it should be exposed to the full sun. As 
the plant, under proper management, is of good habit, it will not, when established, require 
much stopping ; but should it get naked, do not hesitate to cut it boldly in, give it a liberal 
shift, and start it into fresh growth. The Grevilleas arc increased by cuttings of the half- 
ripened wood, and also by seed. The seed may be sown any time between February and 
October, and must be placed in a gentle heat until it begins to grow. The cuttings must be kept 
under a bell-glass, and in a cool house, until they begin to cicatrise ; and then they may be 
placed in gentle bottom heat until fit to pot off. — A .
