NEW OR INTERESTING PLANTS RECENTLY IN FLOWER IN THE 
PRINCIPAL SUBURBAN NURSERIES. 
Bor6nia vimInea. Already noticed at p. 165 of the last Number of our 
Magazine, but without a name. It has since flowered very profusely at Mr. Low’s, 
Clapton, and as the flowers are exceedingly numerous, and are produced throughout 
an almost indefinite period, their smallness is thus in some degree compensated. 
The habit is very elegant. 
Catasetum laminatum. A very curious plant, with half-drooping spikes of 
greenish brown flowers, the form of which last is quite peculiar. The lip is whitish 
in the middle, and hollowed out down each side of the centre so as to leave a con- 
spicuous ridge. It is blooming in the Orchidaceous house of Messrs. Rollisson, 
Tooting, but, like the rest of the genus, is not particularly attractive. 
Catasetum deltoideum. Usually called Myanthus deltoides , the species of 
which genus are now united to Catasetum. Its sepals, petals, and labellum are of 
a greenish brown ground, and prominently marked with transverse bands and 
blotches of dark brown. The shape of the lip at once distinguishes the species, as 
it is very manifestly triangular, or nearly so. A plant of it is flowering with 
Messrs. Henderson, of Pine-apple Place, and it is rather more interesting than 
some species of Catasetum. 
Dendr5bium sulcatum. Ome of the many fine Indian species which have 
been added, within the last few years, to those previously in cultivation. Its stems 
are stout, about nine inches high, enlarging upwards, and becoming prominently 
furrowed after the leaves have fallen. The flowers are developed in drooping 
racemes, of from five to ten or more blossoms, and are of an orange colour, with a 
dark brown blotch on the lip. Though not of quite so brilliant a shade, nor 
unfolding so flatly, as those of some other species, they are extremely showy. 
Messrs. Loddiges had flowering specimens in May. 
Dendrochilum filiformis. Belonging to a new genus, of which it is the sole 
species with which we are at present acquainted, and being, moreover, remarkable 
for its long waving flower-scapes, so thickly covered with blossoms, this plant will 
be valued by the devoted amateur ; but it has nothing which would impress a 
common observer. It has small oblong pseudo-bulbs and leaves, and the scape, 
which at first takes a nearly perpendicular direction, and afterwards becomes 
pendent, is singularly attenuated, while the flowers are ranged very regularly along 
its sides. They are greenish yellow and minute. Messrs. Rollisson have lately had 
it in flower. 
Echeveria pulverulenta. The most noticeable peculiarity of this species is, 
that the leaves, flower-stems, calyxes, and even the upper part of the exterior of 
the petals, are covered with a powdery glaucous matter. In habit, it is most like 
E. gibbiflora , but the leaves are not so large. The flower-stems grow several feet
