Ing THE ORCHID REVIEW. 
entrance covered by a canvas screen. They are placed on a stage erected 
over a border planted with hardy ferns, and are in the most perfect health. 
During the rest of the year they are cultivated in a small house, and the 
temperature kept rather low, sometimes falling to 40° in winter. These 
are the conditions under which the above specimen was grown, and the 
photograph indicates very clearly that the treatment is suitable. A plantof 
Masdevallia racemosa had also nine growths and 135 leaves. Other plants 
which succeed well under this treatment are Epidendrum vitellinum, 
Cochlioda Noetzliana, various Odontoglossums, Oncidiums, and Masdevallias, 
Cattleya citrina, Ccelogyne cristata, Cypripedium insigne, Vandas ccerulea 
and Kimballiana, Sophronitis grandiflora, Lelia majalis, and various others. 
The open-air shelters in which these plants are grown are fitted with 
skeleton frames on which light canvas shading is stretched, to break the rays 
of the sun, and the keen winds when the weather is rough. The results 
prove that if care is taken to keep together the species which require similar 
treatment, especially with regard to sun and shade, many of the coolest 
Orchids will grow and flower abundantly, year after year. Masdevallia 
rosea is one of the coolest-growing species in the genus, as it occurs at high 
elevations in Ecuador, where the climate is naturally cool. We have 
thank the gallant Major for the photograph. 
DIPHYLLOUS CATTLEYAS. 
In a recent issue of the Orchid Review (vol. III., p. 376), I note that you 
think it remarkable that a Cattleya usually producing monophyllous pseudo- 
bulbs should at times come two-leaved. We have five cases of this descr 
tion here in the Cattleya house, and I have photographed and sent you 
prints of two of these, the larger plant being C. Gaskelliana, and the other 
C. labiata (vera), Allow me to tender you my hearty appreciation of your 
work as demon i i 
strated in the Review. Epwarp 0. OSE

[We are much obliged for the photographs, which confirm the observa" 
tion that normally monophyllous Cattleyas may occasionally develop ay 
leaves—probably a reversion to an ancestral condition. The i, 
arose out of a remark at page 268 (respecting the species of the C- got 
group)—‘* Pseudobult always phyl * which would have been be : 
expressed as—‘‘ Psendobulbs normally monophyllous.” | W hen Mr. F: ad 
Moore first called attention to a diphyllous bulb of C. labiata we a y 
that he had a plant of the hybrid C. x Victoria-Regina (supra, TI] Pt’ 
fig. 1), but when he afterwards sent bulb, flower, and photostl ees 
immediately saw it to be typical C. labiata. It is quite possible bee 
species of the labiata group may occasionally develop diphyllous i 
bulbs.—Ep.] i
