position and, above all, a constant supply of fresh air are 
essential. Shading should only be used during the hottest 
sunshine. It does not like to have its roots confined, and 
we find that it thrives most satisfactorily in long cylinders 
of teak. Abundance of water must be given during active 
growth, but from December to the time when the roots 
give signs of new growth but little is needed. 
V. cerulescens.—A distinct and charming species, with 
stems 4in. in diameter and 1ft. to 2ft. high, bearing 
coriaceous, distinctly-channelled leaves 6in. in length, the 
apices of which are unevenly cut. The flowers are Iin. to 
isin. across, and upwards of a dozen are produced on the 
slender, erect scape; the sepals and petals are ovate, 
spreading, slightly incurved, and of a pale purplish blue, 
tie smaller lip being of a rich violet-blue, with the 
anterior portion standing almost at right angles to the 
base. This species was originally discovered in Burmah 
by the eminent Indian botanist Griffiths, in 1837, but was 
not introduced to commerce until 1869.

V. Cathcartii.—‘ By far the noblest species of Vanda. 
No more remarkable Orchid has been found in Northern 
India.” So wrote Dr. Lindley at the time of its intro- 
duction in 1864. Subsequent knowledge compels us to 
somewhat modify this verdict, but V. Cathcartii still remains 
one of the most striking of Vandas. The tall stems are 
terete, and bear two opposite rows of pale green, narrowly- 
oblong leaves, about 6in. long, and unevenly lobed at the
