specimens of Peristeria Parkerii are also now coming into flower, one of which 
is remarkably fine. These gentlemen have just imported a quantity of orchida- 
ceous plants from Demerara, among which they will doubtless have some new ones. 
Mr. Young's, Epsom. Azalea indica variegata. This extremely delicate and 
beautiful variety is now flowering profusely in the greenhouse of this nursery, and 
is perhaps the most elegant and interesting (though not the most showy) of all the 
species and varieties of this genus at present known in our collections. No good 
collection should be without it, as it is a truly ornamental and valuable plant. 
Mentzelia stipitate. A rather new and very ornamental stove plant, which pro- 
duces its showy orange-coloured blossoms very numerously, and in almost constant 
succession, as it has now been flowering at this nursery for several months, and 
appears likely to continue so doing. It may probably prove a greenhouse species, 
but has hitherto been kept in the stove, where, though it flowers so abundantly, it 
does not grow very freely. Mr. Young possesses some splendid specimens of 
Clematis ccerulea, and Sieboldii, now coming into flower ; one plant of the former, 
especially, is cultivated to greater perfection than we ever before witnessed it, and 
the flowers are of a very large size, and a most brilliant colour. Mucuna pruriens. 
Several plants of this singular species are now in flower at this nursery, and though 
an old, it is a valuable and profuse-flowering stove-climbing plant. 
OPERATIONS FOR JUNK 
Any Orchidaceous plants that are now in flower may be removed with safety 
to a cooler house, or, if desired, to a drawing-room, where they will continue 
flowering much longer than if they were allowed to remain in the orchidaceous house. 
The last-mentioned situation is admirably adapted for this temporary translation, 
as, besides being most delightful ornaments to the apartment, they will be effec- 
tually shaded from the rays of the sun, — an object so very desirable at this season. 
They should be taken back to the orchidaceous house as soon as they have ceased 
flowering, that their further growth may not be impeded. Particular attention is 
requisite to shading these plants at this season, and the sun should never be allowed 
to shine directly upon them, neither should they be shaded in dull weather, or 
when the sun is naturally obscured. Stove plants should be most assiduously 
watched at this season, and never suffered to droop for want of water, otherwise 
they will be materially injured. Powerfully syringe all such plants as will bear it 
in the evening of each day, for by this practice, if the house be immediately closed, 
insects, however numerous, will soon be destroyed ; and where there are none, it 
will prevent their appearance, as most of those which infest stove plants cannot 
endure a great degree of humid heat. Every other practicable means should be re- 
sorted to for destroying them at this time, or they will most rapidly increase during 
the summer season. Bulbs that have now ceased blooming should have the quan- 
tity of water applied to them gradually diminished, and ultimately wholly withheld.
