AvucusT, 1914.] THE ORCHID REVIEW. 258 
satisfactory flowering results, owing to the lack of sun to enable them to 
ripen their bulbs to their fullest extent. | 
Such Cattleyas as labiata, Octave Doin, Raphaeliez, Rothschildiana, 
Iris, Venus, Rhoda, and others, will now be completing their growths, and 
throwing up flower trusses at the base of the sheaths. Give them a light 
and airy position, and reduce their supply of water until the blooms are 
well advanced. Vanda ccerulea will now be in spike, and should receive 
plentiful supplies of water, and be well exposed to the light, and, if so 
treated, the flowers will be of good size and rich in colour, enabling their 
beautiful qualities to be brought out to perfection. 
Odontoglossum grande will now be coming away very well, and needs 
abundance of water, a good dose daily being usually required. Weak 
liquid cow manure water may be given twice a week if the grower desires, 
and some successful cultivators strongly advocate its employment, though 
personally I have not observed much benefit from its use. 
The autumn-flowering variety of Epidendrum vitellinum is now fully 
grown and throwing up its spikes of brilliant scarlet blossoms, which wilik 
keep eight weeks or more in perfection. These flower spikes should be 
carefully tied to neat sticks, and a sharp look out kept for slugs, which 
show much partiality for these and also for the succulent roots. 
Any Stanhopeas which have finished flowering may receive fresh rooting 
material, and, if needing more room, should be placed in larger baskets. 
Do not place any crocks in the bottom of the baskets, as these Orchids 
push their flower scapes down and from the bottom of the baskets. For 
compost use a mixture of osmunda fibre and sphagnum moss, and keep 
them damp and syringe overhead frequently. These handsome and 
curiously-formed Orchids thoroughly merit a place in every Cattleya house, 
and since the ideal position for them is to suspend them from the roof, 
many can be thus accommodated, even in a house of small dimensions. 
Among the best known are S. eburnea, oculata, Wardii, and tigrina. 
| SPOT ON VANDA CCRULEA. ier 
| SEND two leaves of Vanda coerulea, hoping to receive your opinion 
about the minute spots which appear on the under surface of the leaves. 
and which turn black after some time. When these minute spots first 
@ppeared, I thought they were caused by thrips or red spider, but this is 
unlikely, for I could not discover these pests. Is it not of fungous nature, 
a fungus which penetrates by the stomata and thrives under certain 
Conditions which prevail in the house ?- It is very curious to note that the 
young leaves which are developing are not touched. The lower leaves, and
