186 THE ORCHID REVIEW. [JUNE, 1923. 
of the species now comprising the sections Huntleya, Bollea and 
Warscrewiczella forbids the formulating of’ any course of treatment for 
them. Doubtless several causes have combined to bring about the failure 
to establish this fine group of Orchids in the glass-houses of Europe, but 
none more so than the withholding of reliable information respecting their 
general geographical station and their environment 77 situ. All attempts to 
cultivate them hitherto*have been purely empiricisms, and even if the 
climatic and other conditions cannot be approximately imitated artificially, 
yet it must evidently be in the interest of importers and collectors to impart 
such information they possess as may tend in any degree to assist the 
cultivator.

NOTEWORTHY PLANTS. 
DENDROBIUM ARACHNITES.—In the Orchid Review of November, 1922, 
reference was made to Dendrobium arachnites. I have in my collection a 
plant, originally purchased from Mr. Keeling, that must have been in 
flower for two months. It has been greatly admired by all who have seen 
it and also gives me a great amount of pleasure.-—A. C. Lister, Thorpe 
Lodge, York. 
DENDROBIUM ACUMINATUM.— While paying a visit to Messrs. Armstrong 
& Brown, Tunbridge Wells, my attention was attracted by a splendid plant 
of Dendrobium acuminatum occupying a basket some ten to twelve inches 
square and which it had already overgrown. It carried no less than five 
spikes, one having 21 fully expanded blooms, another bore 21 buds, and the 
remaining spikes, 18 to 21 buds, The individual blooms are very fine, of a 
rich deep colour peculiar to this species. This grand specimen is a credit 
to its cultivator.— H. A. FARMER. 
CaTASETUM TRULLA.—Another rare plant that I saw at Messrs- 
Armstrong & Brown’s place was Catasetum Trulla, which pore two spikes 
carrying 3 and 5 flowers respectively. The most striking point about this 
fascinating plant is its colour, which, seen at a distance, conveys the im- 
pression of something unnatural, a blackness, so to speak, that is felt. Closer 
examination reveals that the colour is as near black as to make no difference, 
except when a gleam of sunshine falls across it, when one discerns a deep 
brownish lustre cast over the bloom. The broad flat lip is of a greenish- 
yellow, with a darker tinge round the edge. Altogether a weird captivating 
Orchid with an irresistible glamour over it.—H. A. FARMER. 
CYPRIPEDIUM HIRSUTISSIMUM.—Although this fine species was intro- 
duced to england about the year 1857, it was not until 1868—6g ‘hat its 
native locality was known, for it was then that John Day received a 
few plants from his nephew Capt. Williamson, who had gathered 
them on the Assam side of the Khasia Hills. The specific name, meaning
