MaRCH, 19Q11.] THE ORCHID REVIEW. 79 
and whenever water is applied to them take care that it is always of the 
same temperature as the house in which they are growing, as I think many 
cases of spot in the leaves is attributable to this cause. 
GENERAL REMARKS.—Wage warfare diligently against all insect pests. 
Try and work out a method of procedure of all work to be undertaken 
during the coming months, as a well-laid plan of campaign makes work 
more effectual, and easier accomplished. 
FEEDING EPIPHYTAL OrcHIDS.—I have never seen good results from 
this practise, so cannot recommend it. 
CATTLEYA AURANTIACA,. 
I wonder hybridists don’t do something with Cattleya aurantiaca, as it is 
a most potent seed bearer, and nearly every blossom goes to seed—it would 
certainly produce something remarkable if crossed with Brassavola 
Digbyana or some of the Cattleyas, as its colour is such an intense orange. 
I have some dozeh or more plants and they came into my possession by a 
pure accident, in the following manner. While collecting a lot of Cattleya 
Skinneri round the little town of San Felipe, in Guatemala, in 1g09, I took 
quite a number of these plants, mistaking them for C. Skinneri, and you 
may imagine my astonishment when they came into flower. The vertical 
range of C. aurantiaca is very considerable, at San Felipe, 1,200 feet above 
sea level, they occurred with long pseudobulbs as much as 14 inches high, 
while at Moran, at 4,800 feet, I found them with short fat little pseudobulbs, 
about six inches in height; the flowers, however, present no difference, either 
in colour or size. J. C. Harvey. 
[We can only recall two hybrids of Cattleya aurantiaca, E. aurantimedia 
(Orch. Stud-Book, p. 52), raised by Mr. E. O. Orpet in the Thayer collection, 
from C. intermedia ? and C. aurantiaca g, and C. guatemalensis, a natural 
hybrid between C. Skinneri and C. aurantiaca, of which only a few examples 
are known, and which Mr. Harvey might possibly re-discover if he should 
again visit the district when the plants are in flower. His note supplies 
an interesting confirmation of the record that the two parents grow 
together. C. aurantiaca is a somewhat anomalous species, and was at one 
time referred to Epidendrum, hence the name Epicattleya guatemalensis 
under which the hybrid was once described (O.R., i. p. 134), when its history 
was given. It would be interesting to raise this hybrid artificially, as it is a 
very distinct and pretty little plant. 
The flowers of C. aurantiaca are rather small, and from their colour may 
be expected to work out something like Lelia cinnabarina. Its habit 
however, is very different, and it might be worth trying with C. Dowiana, 
C. Forbesii, Lelia xanthina, or any hybrid with yellow in the flowers, as 
yellow is rather a desideratum in the Cattleya group.—ED.].
