plants to Mr. James O’Brien, though from some misappre- 
hension the habitat was recorded as Sierra Leone when the 
species was originally described from the collection of Sir 
Trevor Lawrence, Bart., Burford, Dorking, where it flowered 
in July, 1893. The former locality has since been confirmed, 
for the species has also been collected on the Zomba Hills, 
Nyasaland, at 6,000 feet elevation, by Lieut.-Col. W. H. 
Manning, in November, 1900. It is one of a group of 
Tropical African species, which are for the most part known 
only from dried specimens. 
Descriprion.—Epiphyte, about 6 in. high. Pseudobulbs 
ovoid-oblong, somewhat compressed, 1-14 in. long, covered 
with membranous imbricating sheaths, 2—3-leaved. Leaves 
linear-oblong, subobtuse, recurved, 24-44 in. long, 3-} in. 
broad, subcoriaceous. Inflorescence terminal, 3-6 in. long, 
pubescent ; raceme 4—8-flowered. Bracts broadly rhomboid- 
ovate, abruptly acuminate, puberulous, 4-3 in. long. 
Pedicels puberulous, under 3 in. long. Flowers medium- 
sized, inverted, yellowish green with a rose-pink lip. 
Sepals somewhat spreading, puberulous; dorsal ovate, 
acute, concave, about 4 in. long; lateral ovate, acuminate, 
concave, rather longer than the dorsal. Petals subconni- 
vent, incurved, oblanceolate-oblong, subobtuse, about 4 in. 
long. Lip superior, 3-lobed, nearly 4 in. long; side lobes 
rounded or obscurely angled, subobtuse, short; front lobe 
obovate-orbicular, apiculate, fleshy, channelled, nearly 4 in.

Cuttivation.—Kew is indebted to the Royal Botanic 
Gardens, Glasnevin, for a plant of this pretty species of 
Polystachya, which was received in 1903 and flowered in 
_ June, 1906. There are not many of the numerous species 
of Polystachya that are sufficiently attractive to hold a 
place among garden orchids. Twenty-four of them are in 
cultivation at Kew, and of these the largest flowered is 
P. grandiflora, whilst the brightest coloured is the yellow- 
flowered P. pubescens. ‘The species here figured is at least 
as attractive as either of these. Polystachyas generally 
are easily kept in health if grown in a warm, moist house,
