STYLIDIUM ARMERIA.—ACACIA UNDULiEFOLIA. 
STYLIDITJM ARMERIA. 
L ABILLARDIERE gave this name to a species of Stylewort found in Van Diemen’s Land 5 
and the present plant, collected, we believe, by Mr. Drummond, in New Holland, does not appear 
to differ in any material feature. Our drawing was made in the Chelsea Botanic Garden last summer, 
from a plant which had been presented by Messrs. Henderson of the Pine Apple Nursery. It is a very 
pretty plant, well deserving of cultivation, having the aspect of S. graminifolium, bat possessing 
broader leaves, and larger, as well as deeper-coloured flowers. It comes near the plant which 
Dr. R. Brown has named S. melastachys, and perhaps that is not distinct from the S. Armeria. In 
cultivation, it proves to be a herbaceous perennial, with tall leafless flower-stalks issuing from tufts 
of linear sword-shaped leaves. The scape is smooth below, but clothed with small glandular hairs on 
the upper part among the flowers. The flowers are arranged in a long and tolerably close raceme, 
arising from short stalks in the axils of acute lanceolate bracts of about equal length; they are large 
and showy, of a purplish crimson colour. The flowering stem becomes much longer than the leaves as 
the flowering period passes over, and at seed-time greatly exceeds them.—A. H. 
This pretty species of Stylewort, though a native of New Holland, like many plants from the 
same country, enjoys a little extra heat in the growing season, and the warmth of an intermediate 
house is a suitable excitement for it from February until it begins to show its flowers, when full air 
and light are necessary to give colour. Indeed, a great number of New Holland plants, to grow them 
to perfection, like a gentle moist heat in the growing season, which is, in fact, only in imitation of their 
native habitats, where the heat is much greater than in our ordinary greenhouses. This plant is best 
propagated by seeds, which are produced freely, and require to be sown in sandy peat soil, and to be 
kept in a close frame afterwards, until the young plants get well established, after which they may be 
kept in the greenhouse. The plants may also be increased, but not so readily, by division. The estab¬ 
lished plants require a light rich soil, consisting of sandy loam, peat, and leaf-mould, to which plenty of 
gritty sand and charcoal must be added. After they are potted, place them in a gentle heat, as indicated 
above, and encourage them to robust and healthy growth. To form a fine specimen an established plant 
is necessary, and therefore a succession of young plants must always be grown on. Indeed, to pro¬ 
duce a fine mass, several seedling plants might, at the final shifting, be placed together in a large pot. 
When the plants are thoroughly established, manure-water may be used once or twice a-week, and the 
plants must be syringed to keep them clear of insects, especially of the red spider. Should this, or 
the thrip, another insect pest, at any time infest them, give a good dusting of sulphur after syringing, 
allowing it to remain on for a few days, and then washing it off again.—A. 
ACACIA TJND LLiEFOLIA. 
ITflHIS fine species of Acacia is cultivated in Messrs. Henderson’s Nursery at Pine Apple Place, under 
A the name of A. oleoefolia, but it is undoubtedly the A. undulcefoha of Allan Cunningham, a species 
many years since introduced to our gardens, but apparently lost; for we do not remember to have 
recently seen it in cultivation. It is, of course, an Australian plant, and is one of the finest species we 
possess for the conservatory. Our drawing was made at Messrs. Henderson’s, where it flowers in the 
early spring months. 
It forms a graceful shrub, seldom exceeding four feet in height, and is of variable, irregular habit, 
much branched, the branchlets being of dark colour, crowded with axillary flowers to their very 
extremity, and densely clothed with short, cinereous hair. In the cultivated state the branchlets are 
brown, sub-angular, pilose, and of spreading, dependent habit. The phyllodes are copious, alternate, 
often an inch long, sometimes but little longer than broad, elliptical or ovate, as frequently equilateral 
as oblique, especially in wild specimens. They are of very flexuose surface, with undulated thickened 
margins, or are almost entirely plane, acuminate, with an attenuated, curved mucro; the upper margin 
more wavy than the lower, and, near the base, furnished with a rather prominent oval gland ; smooth.
