86 THE ORCHID REVIEW. [APRIL, 1918. 
careful use of the water pot, are the chief essentials to success with these ‘ 
beautiful plants. 
LycastEs.--Plants of this genus, whether species or hybrids, develop 
new growths immediately they pass out of flower, and any that are in need 
of repotting should be attended to. Specimens that are pot-bound should 
be given larger pots, sufficiently large to accommodate them for at least — 
two seasons. They should have the old material carefully picked out and 
the roots disentangled, as I do not believe in potting Orchids into larger 
pots with their roots an entangled mass. Plants that have lost their roots, 2 
from too much or too little water, should be carefully shaken out and — 
placed in pots just large enough to hold them. Dead and decayed roots — 
and rootless pseudobulbs should be removed. Lycastes succeed in a similar — 
compost to the green-leaved Cypripediums. 
SACCOLABIUMS AND ALLIES.—Aerides, Saccolabiums, Angracums, and ' 
similar plants that require new compost, should be attended to at once, for 3 
ae 
they will push forth new roots rapidly at this season, and as these are very : 
tender, and easily broken, it is advisable to get them done before there is 
any danger of this occurring. Use well-drained pots, and a compost of live 
sphagnum moss, or equal portions of clean At. fibre and sphagnum. 
MAXILLARIAS.—These quaint flowering plants should now be examined

as to their need for more pot room. Such varieties as M. Sanderiana and 
others which are showing their flower spikes should not be disturbed until 
their flowering period is over. Maxillarias are generally grown in pots, with — 
the exception of M. Sanderiana and others which produce their flowers 114 — 
downward direction, and these are best grown in baskets, suspended, where 
their flowers show to advantage. These plants succeed in a similar compost — 
to Cattleyas, and care must be taken that newly-potted plants are nt 
exposed to strong sunshine. 
OponTocLossums.—Any plants of O. crispum, O. Pescatorei, and the 
numerous hybrids of this beautiful genus that are not flowering, and are in 
need of new material, may now have attention, but none should be disturbed — 
unless they are absolutely in need of it. Those having sufficient room, an 
the material in good condition, should not be repotted before the autumn. 
Plants that have their new growths overhanging the edge of the pots may 
be turned out, all useless bulbs removed, and all the decomposed compost 
picked out, after which they should be repotted into the same-sized pot. 
The material for repotting should consist of a mixture of peat, AI. fibre, 
and sphagnum moss, in equal parts, with sufficient small crocks added to 
keep the whole open. Odontoglossums suffer to a greater extent than any : 
other Orchids if allowed to remain in a decomposed compost. These 
remarks also apply to Cochliodas, Odontiodas, and similar plants, which 
for cultural purposes may be treated in almost precisely the same mannet
