FEBRUARY, 1911.] THE ORCHID ‘REVIEW. 37 
represents the original Catasetum Warscewiczii (Lindl. in Paxt. Fl. Gard., 
i. p. 45, fig. 29), with which it agrees precisely. The latter species was 
collected by Warscewiczii in Panama, at 100-400 feet altitude, and was 
introduced by Mr. Skinner, and flowered in the collection of J. D. 
Llewelyn, Esq., Penllergare, Swansea, in April, 1850. Catasetum scurra 
was described as a native of Demerara, but I believe this-is a mistake, for 
Mrs. Lipscomb remarks that her plant was sent from Panama, and it agrees 
precisely with the original description. The two species are very nearly 
allied, and the question arises whether C. scurra may not be a white variety 
of C. Warscewicziil. In any case it is interesting to recover the long-lost 
white-Howered plant. The history of Catasetum Warscewiczii has already 
appeared (O.R., ill. p. 106). R.A.R. 
THE AMATEUR’S ORCHID HOUSE, 
By ALWYN HarRrIsoN. 
(Concluded from page 15). 
Last month I completed a brief survey of my Orchid house, and the plants 
which are now grown, and it remains to deal with the separate structures 
for the Cypripediums and Odontoglossums. 
, CYPRIPEDIUM FRAME. 
The small size of my house necessitated my finding other accommo- 
dation for the Cypripediums, and a frame built from the end of the Orchid 
house, and heated by the hot-water pipes being carried through from the 
house, was erected. The depth of the frame at the back is 3ft. 6in., and 
in front 9 inches, so that ample light is admitted. The plants are stood . 
on pans or on tiles, according to height, these being placed on the natural 
earth. Such a small frame retains the heat well, and the plants are 
sprayed usually twice a day from the end of March till the beginning of 
October, but during the winter they are kept drier, as they are liable to 
damp in this frame. 
For compost I use good yellow loam, a little mortar rubble and osmunda 
fibre. I keep my plants asa rule small by frequent division, as an over- 
crowding of growths at the centre prevents satisfactory flowering. A few 
plants are, however, useful for conservatory decoration, and in repotting 
these I pull them to pieces, and plant each portion round the edge of the 
pot and a few in the centre. In this: way plenty of room is given for 
development. When in bud I remove the plants to the house, placing them 
among the Lzliocattleyas on the staging. 
I sow my Cypripedium seed on the compost of a plant of this genus, and 
the raising of these seedlings is not difficult, but care must be taken to 
water the plant on which the seed is sown only with a fine sprayer, 
otherwise the seed would be washed away. Shade on all bright days by
