FLORICULTURAL NOTICES. 
young plant is then cut off, carefully potted, and shaded a little for a time. It 
rapidly becomes established, and flowers the same season. 
The practice has been adopted with Ipomcea Learii and Allamanda cathartica. 
It would equally suit Stephanotis Jloribundus, and many other species, both stove 
and greeenhouse, where the air was kept sufficiently moist, and the moss constantly 
damp.

NEW OR BEAUTIFUL PLANTS FIGURED IN THE LEADING BOTANICAL PERIODICALS 
FOR AUGUST. 
Aca^cia denti'fera. " A new and very graceful species of Acacia, from the Swan River, with 
unusually long racemes of flowers, longer than the leaves, of a full yellow colour, and highly 
fragrant. These racemes, however, Mr. Bentham observes, run out into leafy branches, and 
thus the species would appear to belong to the division with solitary capitula. The seeds were 
received from Mr. Drummond ; the flowering season of the plant, in an airy greenhouse, is 
March and April, after which it produces its pods tolerably copiously." The plant grows, 
apparently, five or seven feet in height, with simple, linear-lanceolate, falcate, long, and mucronate 
phyllodia or leaves. Bot. Mag. 4032. 
Clo'wesia ro v sea. This elegant plant is "a native of Brazil, and first flowered at Broughton 
Hall, near Manchester, with the Rev. Mr. Clowes, after whom it is named. At a later period 
(March last) it was received from Sion Gardens, by the permission of His Grace the Duke of 
Northumberland, and from that plant the figure was taken. It is very like a Catasetum in habit. 
The stems are from 2^ to 4 inches long, ovate, clothed with the remains of the bases of leaves. 
The leaves are said to be three, lanceolate, ovate, acuminate, and at the point twisting a little on 
one side. The inflorescence proceeds from the base of the stems, and consists of five or six, 
probably more, erect, delicate, white flowers, tinged with pink. They are remarkable for having 
their petals and the end of the lip broken up at the margin into numerous delicate, glandular 
fringes, which give them a very rich and beautiful appearance. As a genus, Clowesia is perfectly 
distinct from everything previously described. Its flowers being extended a little into a chin in 
front, suggest its belonging to the Maxillaridous division ; but its whole habit and the singular 
apparatus of its pollen-masses oppose such an arrangement. The latter organs rest on a broad 
viscid gland, like that of a Catasetum, but the caudicula, or part that connects the gland and 
pollen -masses, is broad, thin, and contracted in the middle, so as to resemble an hour-glass ; but 
whether that is the usual structure" is doubtful. Bot. Beg. 39. 
Cy'tisus Welde'ni. That this species is very different from the common Laburnum will be 
readily seen by any one who has an opportunity of examining the plant. It was figured, in the 
preceding spring, from the garden of the Earl of Ilchester, in Dorsetshire. " It is obviously 
distinguished by its flowers growing in short erect racemes, and not in long drooping ones. 
Although, from its similarity in foliage to the Laburnum, it is liable to be confounded with that 
plant, yet it is in fact nearer C. sessilifolius, of which it may almost be regarded as a gigantic form. 
To what size it will grow is unknown ; probably eight or ten feet high ; but on its Dalmatian 
mountains it is said to be a bush. The poisonous quality of the common Laburnum is still more 
concentrated in this species, as we are told by the German botanists. The General Baron 
Welden, after whom it is named, assures us that its very flowers produce headache, and that the 
goats which feed upon it produce poisonous milk." Bot. Beg. 40. 
Drya'ndra arcto'tidis. " This is one of several handsome species, which Mr. Baxter added 
to the number previously published in the Prodromus Horse Novae Hollandiae; and which 
Mr. Brown introduced into his valued Supplement, which appeared in 1830. It was detected in 
1829, in the hilly region near King George's Sound, on the south-western shores of New Holland.
