£6 THE ORCHID REVIEW. [APRIL, 1917. 
L2LIA ANCEPS and its varieties come under the last-mentioned group, 
and, as they require a long season of growth, all that are in need of new 
material should have attention at once. The compost mentioned for the 
preceding answers their requirements. 
MILTONIA VEXILLARIA, with its hybrids, now about to push up their 
flower spikes, must have water whenever they become dry, though they 
must not receive it in such quantities as to destroy the young roots pushing 
from the base of the half-made pseudobulbs. Before the flower spikes 
attain any length it is advisable to thoroughly clean them in some safe 
solution of insecticide, which will be the means of eradicating any thrip or 
insect pests before their flowering season. At the same time any flower 
spikes entrapped in the leaves should be liberated. 
DENDROBIUMS.—These plants were at one time most popular for 
making a display during the early spring months, but their popularity has 
declined considerably, though they comprise a most useful and beautiful 
class of plants. Many of those which produced their flowers early are 
now developing into growth, which will produce new roots when they 
attain a few inches in height. This is the best and proper season to 
supply fresh rooting material to any requiring it. They succeed 
in either pots, pans, or baskets, according to their character, and they 
delight in a clean fibrous compost of Ar fibre and sphagnum moss. The 
water must pass readily away; therefore, whatever the receptacles used, 
they must be well drained. No water should be given until the new roots 
are seen to be seen pushing through the compost. The plants may be 
slightly sprayed overhead on bright days, but no water must be allowed to 
lodge in the new growths, or decay may set in which will be a severe check 
to the plant. 
ONcIDIUMs.—O. varicosum, and other late-flowering species that are in 
need of new rooting materials may have attention as they start into growth, 
and are about to push new roots from their base. They succeed in the 
same compost as Odontoglossums, but they may receive a more liberal 
supply of half-decayed oak leaves in the compost. O. Marshallianum, O. 
concolor, and others that are developing flower spikes require a moderate 
supply of water to the roots. The warm end of the Cool house provides 
suitable quarters for them the whole year round. Oncidiums, when in full 
growth, and nicely rooted in the compost, delight in abundance of moisture 
both at the root and in the atmosphere. 
taken in watering newly-potted plants. 
ODONTOGLOssuMS AND OponTiopas.—Plants of these genera which 
from any cause are not ina satisfactory condition, may have new material 
given them when their new growths attain a few inches in length, using a 
compost as previously recommended. Nothing is gained by allowing any
