intermediate house to ripen off, and the supply of water 
gradually reduced, finally withholding it altogether. Grow- 
ing most frequently on the upper branches of trees, fully 
exposed to the tropical sun, these plants require but little 
shade. During summer it is convenient to give them a 
place adjoining the Dendrobiums, and in winter one near 
the Cattleyas. They may also be grown on large blocks: 
the preceding method, however, is a preferable one. 
S. Lyonsiii—A handsome, easily-grown, and _ interesting 
species. The pseudo-bulbs are fusiform, about rft. high, 
and bear at the top two or three linear-oblong, leathery 
leaves. The racemes are erect, and bear from twelve to 
twenty-five flowers, each 2in. across; the sepals and petals 
are lance-shaped, white, with several rows of purple dots and 
lines; the lip is recurved at the apex, white, brownish yellow 
at the margin, the disk having several elevated, longitudinal 
lines, spotted with purple. This is a native of Jamaica, 
where it grows on the branches of trees, and on rocks 
exposed to the full sun. A notable character of the flowers 
is their habit of self-fertilisation—an unusual occurrence 
amongst Orchids. The anther-cells open shortly after the 
expansion of the flower, thereby allowing the first wind to 
shake out the pollen-masses upon the viscid stigma.  Intro- 
duced in 1853. The flowers are produced in August.

S. Thomsoniana.—A recently-introduced species of great 
promise. The tapering pseudo-bulbs are similar to those of 
S. tibicinis, but dwarfer. The sepals are strap-shaped, 
somewhat wavy, light yellow; the petals are pale sulphur- 
yellow, with purple streaks on the outside; the side lobes 
of the lip are triangular, rounded, the central one ligulate, 
notched at the apex, and prettily crisped; the disk is 
blackish purple, the apex white. Introduced in 1886. The
