length of time, it being advisable to allow each plant to become quite dry 
and then to afford sufficient water to thoroughly wet the compost. The 
flower spikes generally appear as the pseudobulbs become matured. 
Cyrtopodium send up their flower spikes in conjunction with the young 
growths. When the plants are commencing to finish up their new pseudo- 
bulbs, they should be exposed gradually to full sunshine, and be watered at: 
the roots till the current season’s growths are ripe. At that stage the 
leaves commence to turn yellow, and, if properly matured, soon fall off, 
when root waterings should be gradually reduced. These plants grow best 
on the lighter side of the house, and, if convenient, they should be 
suspended from the roof with their foliage within one foot of the roof glass. 
HABENARIAS.—Such species as H. militaris, H. rhodochila, H. carnea, 
and the new H. Reebelenii are now in full growth, and need abundance of 
water at the roots. As these plants are grown in a rather shallow layer of 
compost, and the principal roots being on or just below the surface, the 
potting materials dry very quickly, therefore the plants should be constantly 
examined to see if water is necessary. Grow these Habenarias in the hottest: 
house, and stand them on inverted pots close to the roof glass, or they may: 
be suspended in shallow pans from the roof, so that they may obtain plenty» 
of light, but not direct sunshine. Diffused light coming through open- 
lattice wood blinds just suits their requirements, whereas they seldom” 
produce fine heads of bloom or dwarf spikes when grown in dense shade. 
A light spraying overhead several times a day, in bright weather, all 
through the growing season is beneficial to them. 
SCHOMBURGKIAS,—The different species of Schomburgkia, as S. tibicinus, 
Kimballiana, Sanderiana, Humboldtii, Thompsoniana, Galleottiana, and 
the rare S. Chionodora, which have hollow, horn-like pseudobulbs, require 
much sunshine at all times, and as these plants are now commencing to © 
grow, they should be placed in the lightest position available in the hottest ~ 
house. They thrive equally well either in pots or baskets, but are more 
easily managed under pot culture. S. Humbdldtii, owing to its scandent 
habit of growth, is more at home when securely fastened to upright teak 
rafts, and suspended close up to the roof glass. Schomburgkias prefer 4 
shallow rather than a deep rooting medium, and this should consist of hard 
Coarse osmunda fibre only, potting each plant with considerable firmness 
Abundance of water is necessary all through the growing season, but when 
the new pseudobulbs are fully made up considerably less moisture should 
be oven Grow the plants where they may obtain almost uninterrupted — 
sunshine, and plenty ot fresh air at all times. To ensure their flowering 
regularly it is essential that the new growths should become thoroughly , 
matured, also that the plants be afforded a long decided rest. "When the 
new growths commence to push out their bunches of numerous young roots,
