ORCHIDS. 
[W. Rollisson & Sons’ 
CATTLEYA DOWIANA (Hooker). 
Costa Rica. 
This fine species, which has been named by Dr. Hooker in honour of Captain J. M. 
Dow, of the American Packet Service, in appreciation of that distinguished officer’s 
gallant assistance to British Naturalists, was first introduced by the celebrated 
Warscewicz, but the specimens, arriving in bad condition, ultimately perished. It w r as 
afterwards discovered by Mr. Arce, a naturalist, while on his search for birds, insects, 
and plants for Mr. Skinner, the well-known amateur orchid grower, and Mr. Salvin. 
Pseudo-bulbs about a foot long, small at the base, and swollen towards the top, sup- 
porting a broad thick leaf, from 9 inches to 1 foot long. The flowers are large and 
extremely beautiful, the sepals and petals being of a delicate nankeen colour* and the 
labellum, which is very large, and of great substance, of a deep velvety purple, 
regularly lined with golden veins which radiate from the centre. 
This is one of the finest Cattleyas yet introduced ; and, as it appears to be of easy 
culture, cannot fail to become an universal favourite.

CYMBIDIUM PENDULUM, var. ATROPURPUREUM 
(Hooker.) 
Java. 
This fine variety, introduced by ourselves from Java, flowered for the first time at 
the Tooting Nurseries in March, 1868. 
The flowers are borne in quantities on spikes of nearly 3 feet in length. The sepals 
and petals are of an intensely dark purple, margined at the tips with green. The 
labellum is recurved, the lateral lobes of which are of a pale purple, the centre one 
white, tinted with rose, and spotted with purple. Dr. Hooker, in describing this 
beautiful novelty in the Botanical Magazine for June, 1868, Tab. 5,710, says, “The 
leaves were 3 feet in length, and spikes of 2h feet, presenting a truly noble appear- 
ance, far surpassing any of the other varieties of the same species hitherto discovered.”

CYPRIPEDIUM LyEVIGATUM (Bateman). 
Philippines. 
Although introduced in the early part of the year 1865, this splendid and most 
interesting species remains among the rarest Orchids at present in cultivation. It is 
the nearest ally we have to the fine C. Stoneii, and, like that variety, has glossy and 
shining leaves, but differing from it in the colour of the lip, as well as in the length 
of the petals. Again, the dorsal sepal of C. Icevigatum is striped on the inside 
with crimson, while that of C. Stoneii is white within, and striped with crimson on 
the outside. This very curious and distinct species was found growing on the roots of 
Vanda Batemanii, which had established themselves on some rocks close by the sea 
shore of a small island of the Philippine group — a fact which unmistakeably points to 
the proper treatment of the plant as far as temperature is concerned.
