220 THE ORCHID REVIEW. [JuLy, 1923. 
Lelias should be kept growing without a check until they have reached the 
flowering stage. If possible they may be afforded rather a warmer 
temperature than the parent plants. Greater success is obtained when a 
house is devoted entirely to raising and growing seedlings, affording them a 
winter temperature of from 60° to 75°, and a moist atmosphere at all times. 
Remove the plants on into larger pots as they require increased rooting 
Space, and never allow them to become pot-bound. 
L#LIA PUMILA.—This small cool-growing Lelia is now making new 
growth, and as young roots develop from the base they should be repotted 
or have fresh materials applied at the surface. These plants require liberal 
supplies of water at the roots during their growing season, therefore it is 
important that the compost is sweet and in a porous condition. Shallow 
pans without side holes, with wires attached for suspending are suitable 
receptacles, these should be well drained. Use only a thin layer of soil, 
which may be composed of osmunda fibre and sphagnum moss cut up 
rather short, with crushed crocks mixed to ensure porosity; press the 
compost rather firmly round the base of the plant and prick in a few live - 
heads of sphagnum moss over the surface. For a short time after re-potting 
water should be sprinkled over the surface only, and when the young roots 
have become well established in the new compost, the plants should be 
dipped in tepid rain water each time the soil becomes dry, and sprayed over- 
head whenever the weather is favourable. This treatment should be 
continued till after the plants have passed out of flower, when they should 
be kept slightly on the dry side throughout their resting season. 
ODONTOGLOsSUM CITROSMUM.—By the time plants of this Mexican 
species have passed out of flower, the young growths will be well advanced, 
and as they push forth new roots from the base they should be repotted if 
necessary, ordinary Orchid pans of medium depth may be employed, as 
these plants are not of a vigorous rooting kind. The pans should be just 
large enough for two seasons only. Afford good drainage, and a shallow 
compost of osmunda fibre cut up rather short. In repotting remove all 
useless back pseudobulbs, pot firmly, and suspend the plants near the roof- 
glass in the lightest part of the intermediate house. Apply water sparingly 
until the new pseudobulbs are getting near completion, when the compost 
should be well watered each time it becomes dry. When the growth is 
fully developed, water should be gradually withheld, and the plant given a 
long season of rest.

Mr. A. Warburton, and famous for the fine varieties of Odontoglossum 
crispum of the best old Pacho type, is to be sold by private treaty. Full
