_ AUGUST, 1912,] THE ORCHID REVIEW. 239 
month or the end of April being the best time. Be careful not to injure 
any of the aérial roots in the process, for, although thick, these are very 
_ brittle. Many should now be showing spikes, and must be well supplied 
with pure rain water, and sprayed overhead in the early morning. 
Any Stanhopeas which have finished flowering, and require fresh baskets, 
should now be attended to. Do not put any crocks in the bottom of the 
new receptacle, for they push their flower scapes down between their roots, 
and often from the bottom of the baskets. For compost, use a mixture of 
osmunda fibre and good fibrous peat, in equal parts, with some heads of 
living sphagnum moss. Keep them damp overhead, but do not give much 
water direct to the plants until they begin to take hold of the new compost. 
This is now the usual blossoming season of many of the hybrids of 
Cattleya Warscewiczii (gigas) and Dowiana aurea, also of Lelia cinnabarina 
and purpurata, and amongst the best undoubtedly must be included C. 
Hardyana, C. Pittie, C. Rothschildiana, C. Octave Doin, Leeliocattleya 
Phoebe, L.-c. Hypatia, L.-c. G. S. Ball, and L.-c. eximia. Next month 
several important details will be dealt with. 
SUGGESTED ADDITIONS. 
ODONTIODA VUYLSTEKE&.—This was the first member of this gorgeous 
bigeneric race which reached a flowering stage, and caused a great sensation 
on its appearance a few years ago. Since then many beautiful forms have 
appeared, of which Lady Colman, Crawshayana, and Marjorie Statham are 
the best. The typical variety has sepals and petals of a creamy white, 
almost wholly covered with scarlet blotches, and the lip yellow with red 
markings. This fine hybrid can now be procured at moderate cost, and 
together with O. Bradshawiz (O.R., xix. 135) and Charlesworthii, form a 
good selection for an amateur’s Cool house. Odontioda Vuylstekez is a 
hybrid between Cochlioda Neetzliana and Odontoglossum Pescatorei. 
ORCHID SPOT. 
WE have received from a correspondent a leaf of Lzliocattleya rubens, 
which has decayed rapidly, the sender remarking that it has “ gone off 
within the last ten days, beginning at the point and eating down a little 
each day.” The house is said to have been shaded from all direct sunshine. 
We cannot detect the presence of any fungus mycelium, nor yet of any 
mechanical injury to the leaf itself, for the epidermis is uninjured, hence we 
suspect it to be some form of the disease known as Orchid spot, which is 
usually of a local character, and is often attributed to cold drip from the 
roof, particularly during the winter months. We should like to know if 
the remaining leaves on the plant remain healthy, also if other plants in 
the house are affected. We think that some cultural defect is generally 
the cause of this malady.
