NEW AND RARE PLANTS IN FLOWER.

is pure white, whence the species derives its name. Several fine specimens 
are now producing three or more spikes of flowers with the gentlemen before 
named. Dendrobium amplum. A most remarkable species, differing very 
materially from those previously known. The stems which proceed from the 
base of the plant are eventually formed into perfect pseudo bulbs, very much after 
the manner of some of the species of Eria, and the flowers, which in the specimen 
now noticed are solitary, are of a most curious construction ; they are greenish- 
yellow, and very prettily spotted with brown. "We should certainly be disposed 
to question its relation to Dendrobium, but Messrs. Loddiges have the authority 
of Dr. Wallich for the above name, and their specimen corresponds to the figure 
published in his splendid work on the Asiatic Flora. Ccelogyne fuligiiiosa. This 
is a new and very interesting species, with flowers of a light brown colour ; 
the labellum, which is beautifully fringed, being of a very dark brownish purple 
hue. The flowers are about an inch across, and appear to be produced rather 
sparingly, though, from the smallness of the plant in the collection of these gentle- 
men, this latter feature is probably not a permanent one. The whole of the 
above beautiful species, as well as Oncidium Henchmannii, Burlingtonia Candida, 
and several other very rare orchidaceous plants, are now flowering in fine per- 
fection at this nursery. 
Mr. Low's, Clapton. Salvia patens. This splendid and valuable species still 
continues flowering at the above nursery, though it has recently been removed to 
the greenhouse. Such is its propensity to flower, that it is very rarely that 
cuttings can be procured free from flower buds, so that some difficulty is experienced 
in propagating it. To those whose object is the production of flowers, with little 
regard to obtaining a stock of it, this plant will be a most invaluable ornament 
both to the greenhouse and the flower-garden. Another new species of Salvia, 
with much smaller flowers, and of a less intense blue colour, is also in flower at 
this nursery, and is both interesting and ornamental. A pretty little new plant, 
evidently belonging to the natural order Labiatw, and supposed to be a species of 
Gardoquia, which has been raised from Mexican seeds, is flowering very profusely 
in the greenhouse of this gentleman. Also a species of Pentstemon from the 
same quarter, the flowers of which resemble P. gentianoides in colour, but they 
are much smaller, and the leaves are of a lighter green colour, and much serrated. 
Messrs. Rollison's, Tooting. Oncidium Lanceanum. The splendid specimen 
of this most magnificent plant, which we have before noticed as being in the 
possession of these gentlemen, is now most profusely in flower ; but, owing to the 
lateness of the season, the flowers are not of that deep rich hue which usually 
characterizes them. It is, however, a most interesting object, and all lovers of 
orchidacese would derive a considerable degree of gratification from witnessing it 
in its present state. Oncidium raniferum. This pretty little species is flowering
