298 THE ORCHID REVIEW. [OCTOBER, 1903. 
factorily ; but this, we are inclined to think, chiefly arises from too low a 
temperature, for it is by no means an alpine plant. Its habitat is in the 
province of Antioquia, on the slopes of the hills near the river Atrata, a 
tributary of the Cauca. Here it grows on trees and rocks, mostly in shade, 
and at 1,000 to 2,000 feet elevation, sometimes associated with Oncidium 
Kramerianum. Such a habitat suggests warmth, shade, and moisture as 
among the plant’s requirements, and it is in such a house that Messrs. Low 
grow it. It may be described as Warm or Warm-Intermediate, and some 
growers find it succeeds admirably in the Phalenopsis house. Mr. Burberry 
once remarked :—“‘ The best position I can recommend for this is a natur- 
ally damp one. It often happens that the foliage of the plants is covered 
with moisture at early morning in one part of the East Indian house more 
than another. It isin sucha place that Miltonia Roezlii will flourish if 
not too heavily shaded” (Orch. Rev., ii, p. 89.). Moisture seems to be 
specially important, and Messrs. Low find that a layer of moss round the 
base of the pots is conducive to that degree of humidity in the atmosphere 
which the plants like. Care, however. must be taken not to overdo it 
during the dull winter months. As regards potting, no special treatment is 
required, but cleanliness is a very important item, for thrip and red spider 
will soon work havoc among the foliage if allowed to establish themselves. 
Dipping the plants and vapourising at intervals are the approved remedies. 
A compost of one part peat fibre and two parts of sphagnum moss, and 
the use of rather small pots or pans, has been recommended, but we 
suspect that an admixture of oak leaves would prove beneficial. We 
should be glad to know if the new compost has been tried for this 
species.

SOBRALIA CATTLEYA. 
THE flowering of the remarkable Sobralia Cattleya isan event which should 
not be passed over in silence, and we find the following note respecting it 
jn an account of the Zoological-Botanical Garden (Diergaarde), at 
Rotterdam (Gard. Chron., 1903, ii, p- 220):—** A specimen of the large- 
flowered Sobralia Cattleya was remarkable for its great size and healthy 
appearance. It is in a mammoth pan, and had eighteen or twenty growths 
five feet high. It flowered two years ago.” We should be glad if 
Mr. Wilke would send us further particulars, as thi
