140 THE ORCHID REVIEW. {May, 1910 
flowering season is over. The same treatment applies to D. bigibbum and 
D. superbiens. 
LycasTEs.—L. Deppei, L. leucantha, L. aromatica, L. x Tunstillii, L. 
X Balliz, L. Skinneri and its various varieties will now be ready for 
tepotting. A goodcompost for these consists of one-third each of fibrous 
loam, peat, and sphagnum moss. The compost should be in a fairly rough 
state, and well mixed together. Use pots large enough to last them two 
years. Fill the pots about one-third full of crocks for drainage, and pot 
moderately firmly. They should be placed in a shady part of the Inter- 
mediate house, and till they get well rooted only sufficient water to keep 
them from shrivelling should be given, but when well rooted they require 
copious supplies till the bulbs are finished. If there are a number of bulbs 
without leaves they may be cut off, leaving four behind the lead to form the 
plant. Choice kinds may be increased as follows: the old bulbs should be 
placed rather low down in a pot just large enough to hold them, with a few 
crocks at the bottom, then put sphagnum moss round them so as to reach 
about half way up the bulbs. They should then be placed in a moist and 
shady corner where they will be out of the way. They often break away 
very quickly, though sometimes it is quite two years before they do so, but 
a good variety is well worth waiting for. 
ODoNTOGLossuMs should now be kept as cool as possible. It is 
impossible to keep the temperature at any stated figure during the four 
hottest months, but much may be done by judicious shading, damping and 
ventilation. The use of fire-heat can be dispensed with during the day- 
time, but for the next week or two sufficient to take the chill off the pipes 
may be used at night, as it will save the flowers from getting spotted, which 
they quickly do when the pipes are cold at night. Sufficient bottom 
ventilation may be used to counterbalance the small amount of fire-heat 
necessary. QO. grande and O. Insleayi leopardinum, after having had a 
good rest since making up their bulbs last season, by having been kept on 
the dry side through the winter, are now making new growths, and should 
be attended to. Repotting should now be done, using the polypodium 
compost as recommended in January. Water should be sparingly applied 
till the young roots are well into the compost, when the supply can be 
gradually increased to meet requirements. Those that do not require 
repotting should be stood in a pail of water and allowed to have a good 
soaking, to make sure that the compost is moistened right through. They 
should then be allowed to get nearly dry before watering again in the usual 
way, but should never be allowed to get quite dry at this season. 
SOBRALIAS.—Many of these are now showing for flower, and if at all 
root-bound they may be occasionally watered with weak liquid cow manure, 
which will be of benefit to them whilst developing their flowers. There are
