more abundantly. They flower later than the coloured kinds, and also 
grow somewhat later, so that they will require attention after the coloured 
forms. 
CypRIPEDIUMS.—During the present month a commencement may be 
made with the repotting of plants that flowered in the autumn. The pots 
should be well drained, and the plants potted moderately firmly, using a 
compost of two parts best fibrous peat, one part ar and loam fibre, and a 
liberal admixture of sphagnum moss. If the loam is not of a fibrous nature, 
a liberal mixture of broken crocks will be beneficial. The later-flowering 
varieties, which are in full bloom or pushing up their spikes, will follow on 
at a later date, and must have water whenever they become dry. In potting 
the tessellated-leaved section, the loam fibre is best left out, as this section 
I find succeeds better without it. This is less essential in hybrids between 
the two sections. 
Decripuous CALANTHES.—These useful Orchids, as they pass out of 
flower, should be placed in a safe position to rest, avoiding too low a 
temperature or a place where drip or water from any source may reach 
them. Repotting will not be required for some time. 
OpontoGLossums that are showing for flower should be carefully and 
neatly staked as the spikes attain sufficient length. Such plants are best 
placed in a position by tl lves, so that they can easily be examined from 
time to time for slugs, which devour the spikes and do irreparable harm. 
Small, weakly plants should have their spikes removed as soon as they show, 
as these should not be allowed to produce flowers until they get fairly strong, 
and then only be allowed to produce one or two flowers. The usual precau- 
tions against attacks of thrip and other pests must have continual attention. 
Plants which are in need of new material, and whose new growths have 
attained some few inches in length, may be repotted. A suitable compost 
consists of equal portions of peat, Ar fibre, sphagnum moss, and clean 
broken leaves. 
MILTONIAS.—-The autumn-flowering Miltonias will soon need attention. 
The young roots are emitted soon after the new growth gets away, and when 
these are visible any necessary repotting should be done. A suitable compost 
consists of two parts peat, two parts sphagnum moss, and one part leaf soil, 
mixed with some small broken crocks. The spring and summer-flowering 
varieties are now growing strongly in the Intermediate house, and should 
have water afforded them whenever they become dry. Whilst in full growth 
these plants should not be allowed to suffer for want of water at the roots, 
and their surroundings should be fairly moist, as a preventive against thrip, 
their arch enemy, espécially when much artificial heat has to be used to 
maintain the temperatures. is
