FLORICULTURAL NOTICES.

CymbIdium pendulum. From specimens transmitted by Dr. Wallicli to the 
Hon. and Rev. W. Herbert, and flowered successfully in that gentleman's collection, 
the drawing now under remark has been prepared. The species was first found by 
Dr. Roxburgh, on trees, in the province of Sylhet ; Dr. Wallicli afterwards met 
with it in Nepal. It approaches nearest to C. aloifolium in habit ; but is essen- 
tially different in its flowers. " Its leaves are from two to three feet long, stiff, 
leathery, obliquely obtuse, and strongly furrowed ; at the base they form a distich- 
ous tuft, like that produced by the equitant leaves of an Iris. The flowers exceed 
in size those of any of the species nearly allied to this ; they are, however, of 
a dirty yellowish-brown colour, which diminishes their beauty, notwithstanding 
the clear red and white of the labellum." As the flower-spikes are pendulous, 
it appears to require suspension on a block of wood, from the roof of the Orchida- 
ceous house. Bot. Reg. 25. 
Dahlia glabrata. A new species of Dahlia is not altogether a novelty in the 
present day, as several have latterly been introduced. D. glabrata is, however, 
considered perfectly distinct. Mexico is its native country, and it was procured 
from thence by G. F. Dickson, Esq., by whom seeds were given to the Horticul- 
tural Society. Its leading characteristics are lilac flowers, with an apparent dash 
of purple in the centre, and very long roots, which are of uniform thickness. 
Dwarfness is also one of its peculiarities, and it is conjectured that by repeated 
impregnation with D. scapigera, (another new species,) a race of Dahlias, pos- 
sessing a constantly dwarf habitude, and thus far superior to those now cultivated, 
may ultimately be obtained. It is better to cultivate this as a half-hardy annual, 
saving the seed each year, and allowing the roots to perish. Its blossoms are 
developed from the end of July till the arrival of frosts. Bot. Reg. 29. 
GrevIllea dubia. This would seem to be one of the most attractive species 
of the singular genus Grevillea. " Mr. Brown considers this plant scarcely specific- 
ally distinct from his Grevillea punicea ; Roomer and Schultes repeat the doubt, 
and Sprengel unites them." Dr. Graham states, however, that G. punicea " is 
distinguished from this by its leaves being broader, larger, and minutely dotted, 
but otherwise glabrous on the upper surface, where also the marginal nerves are 
less conspicuous ; the raceme, too, is less dense, and the style longer." If the 
colour of the flowers is correctly represented in the Magazine before us, this may 
likewise be added as a peculiar trait, it being of a pale pink. The shrub grows 
about five feet high, branches profusely, and bears a great number of its pleasing 
rose-coloured blossoms in close clusters to the end of the season. Bot. Mag. 3798. 
Monachanthus roseo-albus. Sir W. J. Hooker has here retained the 
generic name Monachanthus, more from a regard to consistency, than a conviction 
that it ought to be separated from Catasetum. Of the species he remarks, " several 
pseudo-bulbs of this remarkable and very pretty plant were sent from Para, in 
Brazil, to Mr. Murray, of the Glasgow Botanic Garden, in the early part of last 
year, by Mr, Campbell, and there is scarcely any period since that some one or other
