NOTICES OF NEW AND RARE PLANTS 
IN FLOWER IN THE PRINCIPAL NURSERIES IN THE VICINITY OF LONDON. 
Messrs. Henderson's, Pine Apple Place. Siphocampylus bicolor. A fine 
specimen of this very interesting plant is now flowering profusely in the greenhouse 
of this nursery. It has previously been figured and described in this work, and 
we have only now to notice an excellent feature in its character, which is, that it 
continues flowering in almost constant succession for several months. Lophosper- 
mum scandens. This pretty new species is also beautifully in flower in the green- 
house of these gentlemen, and deserves extensive notice and cultivation. It 
appears to be a remarkably free-flowering plant, an abundance of flowers being 
produced when only two feet high. Pentstemon Cobcea. The large and handsome 
blossoms of this beautiful plant constitute it the finest species of this genus at 
present known in our collections, and it is much to be regretted that such great 
difficulty is experienced in propagating it, and preserving it through the winter. 
It is now in flower in the above nursery, and the flowers are full an inch across 
at the mouth ; but it is remarkable how they vary in colour, as in the present 
instance they are nearly white, while we have sometimes seen them of a deep 
pink colour. Undoubtedly soil and situation must exercise a material influence in- 
effecting these changes, and it is most probable that light is the principal agent. 
Mr. Knight's, Chelsea. Oncidium Lanceanum. Two specimens of this 
splendid and delightfully fragrant species are now exhibiting their lovely blossoms 
in the orchidaceous house of this gentleman. This is, without doubt, one of the 
most beautiful of orchidaceous plants, and beside the richness and diversity of the 
colours of its flowers, the shortness and boldness of the spikes on which they are 
produced is a valuable feature in its character, as the flowers are thus brought 
nearer to each other, and their combined beauty rendered more conspicuous. 
Aspasia epidendroides. This is a very neat and interesting little orchidaceous 
plant, with flowers containing a great variety of showy colours, and much re- 
sembling those of A. variegata. It is now flowering at this nursery, and should 
be in the collection of every lover of orchidacege. Drymonia bicolor. This fine 
stove climbing plant is again in flower at the above nursery. It is a species of 
considerable merit, as it grows rapidly and flowers very profusely :. the flowers, 
though not remarkable for showy colours, are highly interesting and ornamental. 
Messrs. Loddiges, Hackney. Maxillaria stapelioides. This is an excellent 
and truly ornamental little plant, the flowers of which, as its name implies, 
bear a striking resemblance to some of the species of Stapelia. They are produced 
in very great profusion, and when a number of them are expanded, (which is at 
present the case in the collection of these gentlemen,) the plant has a most inte- 
resting appearance. The leaves are pale green, and the flowers are likewise of a 
green-coloured ground, but most profusely and beautifully spotted and marked 
with purple. Maxillaria graminea. This is another pretty species of the genus
