FLORICULTURAL NOTICES. 
Acro'phyllum verttcilla^tum. Here is the lovely Acrophyllvm ( Weinmannia) venosum with 
a fresh name ; though it is extremely doubtful whether the present appellation will be at all 
adopted. " My first knowledge of this plant," writes Sir W. J. Hooker, " was derived from 
specimens gathered on the Blue Mountains of New Holland by Mr. Allan Cunningham, who 
transmitted them to England under the name of Weinmannia, a genus to w hich it is doubtless 
nearly allied." It has been referred to a genus called Calycomis by Mr. Brown, and adopted by 
Mr. Don. The propriety of such a name is questioned by Sir W. J. Hooker. " The plant is 
peculiarly handsome ; it was introduced into our gardens by Mr. Allan Cunningham, and, with 
the common treatment of the greenhouse, it flowers in great profusion during the spring months."

A'erides a'ffine. " There is a peculiar delicacy and beauty in the Orchidacese of the East 
Indies, and especially in the genus to which the present plant belongs, which, combined with the 
difficulty of obtaining them, renders them peculiarly valuable to the cultivator, a'ad causes them 
to be eagerly sought after. Aerides affine was sent to the Royal Botanic Gardens of Kew by Dr. 
Wallich, from the mountains of Nepal, near Sheopore. It had been previously found in Sylhet, 
by Dr. Roxburgh. Our plant, however, graceful and elegant as it is, is very inferior to the 
native specimen represented in Dr. Lindley's splendid " Sertum Orchidaceum," from a drawing 
in the possession of the Honourable the Court of Directors of the East India Company. In 
another respect, too, it differs : the racemes of flowers are there represented erect ; with us, 
the flowers, and, indeed, the leaves too, are drooping. In the Orchidaceous stove it blooms in 
April." The leaves are narrower than those of most other species, and the flowers are pale 
rose, blotched with rosy purple, being produced in long racemes. Bot. Mag. 4049. 
Alstrxeme'ria lineatiflo ( ra. ft At last we have the pleasure of publishing the true Jlstrce- 
meria lineatijiora, from Peruvian roots presented to the Horticultural Society by John Maclean, 
Esq., of Lima. It is one of the finest of its class, and although doubtless very near A. Ligtu, 
peregrina, and pulchra, apparently distinct from either. In addition to the discriminating marks 
between these beautiful species pointed out by the learned investigator of the genus {Herbert, 
Amaryllidacece, p. 93), it will be found that A. pulchra has the sepals and petals constantly 
serrated, which is never the case in the other three, and that the form of their leaves or sepals 
affords clear marks for further discrimination. In A lineatijiora the leaves are short, very 
blunt, and of nearly equal size ; in A. peregrina they are also of nearly equal size, but very 
sharp ; and in Ligtu the upper are very narrow and taper- pointed. Then as to the sepals : in 
A. peregrina they are deeply obcordate ; in pulchra narrow, spatulate, obovate with a little 
point ; in Ligtu roundish -obovate, with a very small point ; and in lineatijiora obovately wedge- 
shaped, with a large point. By these marks it appears that these species may be certainly 
distinguished ; and that, being so, we are constrained to regard A. lineatijiora as a good species, 
and not a mere variety of Ligtu. It is a greenhouse perennial, and thrives best in a compost 
consisting of one half loam, the other peat and sand. This, like many other species of Alstrce- 
meria, produces tuberous roots in a horizontal direction, consequently it requires a large pot, 
which should be nearly half filled with potsherds. In autumn the plant should be set in some 
airy place, where it will receive very little water, until the beginning of January, when it should 
be repotted. While in a growing state, plenty of water should be given, and air at all times 
when the weather will permit. It may be propagated abundantly from seed." Bot. Reg. 58. 
Dendro'bium Ru'ckeri. " We presume this plant to be one of Mr. Cuming's discoveries in 
the Philippines, although no trace of it is to be found among his dried specimens. It belongs to 
the same set as D. Pierardi, among which it is one of those with yellow flowers. Although it 
may not be so handsome as some of these, yet it is a very fine species, and perfectly distinct, both 
in colour, habit, and the structure of the flowers. Its leaves are exactly lanceolate, very sharp- 
pointed, and a little disposed to curve backward at the end. The flowers, although of a rich 
yellow-nankin colour when expanded, are almost white externally ; their lower sepals, which 
are really ovate in form, are rolled back at the edge, near the middle, so as to look as if con- 
tracted there. The petals and upper sepal are nearly of the same size and form, linearly- 
obovate, acute, and spreading. The labellum is deep orange, with a white edge and a pale pink 
outside ; when spread flat it is roundish obovate, with three rounded lobes, of which the middle 
one is crisp, and has a hairy ridge running along the middle ; the side lobes are hairy, too, near
