plant resembles C. amethystoglossa and C. Leopold, but it is not so robust. Mr. 
Wise, the gardener, grows it in rough fibrous peat, giving good drainage. Pot culture 
suits this class of Cattleyas best. They must be well elevated above the rim of the 
pot, so that the roots may run over the surface, as, when buried in the peat, if 
they get over-watered, they are apt to go rotten. A little charcoal placed on the 
top of the peat is advantageous, as the roots lay hold of it freely; and it is also 
desirable to mix a portion with the peat, as it renders it more porous, and allows 
the water to pass off more freely, thereby helping to keep the compost sweet. This 
latter is a matter of great importance to the plants, for Cattleyas, like many other 
Orchids, do not like the soil in which they are planted to set too closely together 
to the exclusion of fresh air from their roots. There is no doubt the access of 
fresh air keeps them in a more vigorous condition. In support of this it may be 
noted that in their native country they are found on trees, where they get a free 
circulation of air, their roots being merely sheltered by the small quantity of moss 
or decayed leaves from the trees which may collect about them, while many of 
them luxuriate with their roots suspended in the air. 
This Cattleya is one of those which should: always be kept plump in the 
stems and leaves, for if allowed to shrivel it will be found difficult to get them 
again into a plump healthy condition. Give all the light possible, so that the 
stems may be well ripened. A great deal of success depends upon the thorough 
maturation of the successive growths, for if they are weak or immature they will 
produce but puny results. The plants require the same temperature as C. Triana.

Cartteya Mossta#.—We have lately received from De Barry Crawshay, Hsq., 
Sevenoaks, flowers of a fine series of varieties of Cattleya Mossiw. The flowers 
were all large and very richly marked, some of the colours being. exceedingly 
distinct, and the lips very large.—B. 8. W. : 
DenprosiuM Deraret.—We were agreeably surprised to see this novelty exhibited 
by Sir T. Lawrence, Bart., at the Summer Show of the Royal Horticultural Society. 
The flowering bulb was two feet six inches high, and was furnished with two spikes 
of flowers. This species seems to differ from the formosum section of the genus, 
by throwing out lateral as well as terminal spikes. The flowers were about thirty 
in number, pure white, with a slight tinge of green in the throat. In shape they © 
resemble those of D. Jamesianum, but they are somewhat smaller—H. W.
