be prepared at the foot of the wall on a level with the stage, in which the allied 
species of ascending habits, as Cereus Mallisonii and Colvillii, may be planted and 
trained up the wall, using them like the descending plants for stocks, on which to 
graft the Epiphyllous sorts. 
Hitherto, we have confined ourselves to the procuring variety by clothing the 
back wall of the house. Of still greater moment is the furnishing of the upper 
portion beneath the glass, and gaining ornamental objects which shall depend 
naturally from the roof. By a recent visit to a beautiful little establishment near 
London, we are enabled to make known a way of obtaining that desideratum, 
since the plan we shall sketch is there carried out with remarkable success. It is 
simply to train the Pereskia aculeata in any requisite quantity over the roof, or up 
the rafters, and graft upon it various species of Epiphylla^ especially tlie varieties 
of truncatum^ as well as Cereus JlageUiformis^ and some others. These, hanging- 
down loosely into the air, impart, at all times, a most delightful variety, and when 
in bloom must be striking and beautiful in the extreme. It is merely necessary 
that the Pereskia be planted in a good free soil, and that its roots be not subjected 
to prejudicial influences, of which shade and too much water may be particularly 
specified. 
It must not be surmised that the adoption of any of these hints is to be confined 
to succulent houses. There, of course, the systems will be most appropriate. 
But they will be as productive of interest, and almost as successful, in any common 
stove, or a house of a temperature between that of the stove and the greenhouse.

NEW AND BEAUTIFUL PLANTS FIGURED IN THE LEADING BOTANICAL PERIODICALS 
FOR AUGUST. 
Alstr(EME'ria nemoro'sa. a liandsome species, which "first flowered in the winter of 
1841—2, in the greenhouse of Messrs. Veitch and Son, of Exeter. The roots were found in the 
Organ Mountains of Brazil, by Messrs. Veitch's collectoi-, at an elevation of about 3000 feet. One 
of the plants, having been set in the open border, has endured the winter, as well as A . aurea, 
and was moved in the spring ; but in consequence of having been planted out late, the flower-stem 
produced in the autumn was cut by frost." It is thought by the Hon. and Rev, W. Herbert to 
be nearly related to A. aurea; but Sir W. J. Hooker remarks that " its almost campanulate and 
nearly regular flowers, the marking of the petals and sepals, the shape and size of the leaves, and 
the colour, indicate a species quite distinct from A. aurea,' and from every other member of the 
tribe. It has reddish sepals, with a yellow band down the middle, and yellowish petals, a little 
spotted below. The month of May or June would seem to be its proper blooming period, as it 
was exhibited in the first of these at the great Chiswick show. Bot. Mag. 3958. 
Aspa'sia epidendroi'des. This is a rather showy Orchidaceous plant, the flowers of which 
last a considerable time, and change their colour after being expanded a few days. They do not, 
however, open with sufficient boldness, and too often present a starved appearance. They are 
produced in a short upright raceme, the sepals and petals being almost covered with broad trans- 
verse brown bars or blotches on a yellowish ground. The lip is large and whitish, with a bright
