the stove. We find they are happiest when hung against 
a moist back wall where they obtain plenty of direct sun- 
light. During winter little water is necessary: sufficient, 
however, should be given to prevent shrivelling. In summer 
the blocks should always be moist: they may be syringed 
two or three times on sunny days. 
S. Hadweniii—A very handsome and interesting species, 
with terete, dark green, usually pendent leaves, 14ft. long, 
pointed, grooved on one side; they are neither so long 
nor so flexible as those of the better-known S. Steelii, 
and may occasionally be seen growing erect. The flowers 
are produced singly on short scapes, and measure upwards 
of 4in. at their widest diameter; the sepals and petals 
are oblong, pointed, greenish yellow, boldly blotched with 
reddish brown. The lip is 14in. broad, the sides turned 
up, and the margin wavy; it is white, blotched with pale 
rose, contrasting prettily with the rest of the flower. At 
Kew a healthy example of this plant has for many years 
been grown in a sunny position in an intermediate house, 
where it thrives, and flowers regularly. This species 
deserves a more extended cultivation. It is a native of 
Brazil, and was introduced in 1851. Syn. Szfrenaria 
Hadwenitz.

Var. della is a beautiful variety, with sepals and petals 
yellowish outside, bright crimson spotted and blotched with 
pale sulphur inside; lip white, spotted with light brown on 
the disk and side lobes, and with mauve on the front lobe. 
Var. pardalina is a rare and equally beautiful variety, 
with brown, circular markings on the sepals and petals. 
S. Steelii—Although terete leaves are not unfrequently 
met with amongst Orchids, in no kind do they attain such 
a length, or afford such a distinctive character, as in
