matter is not cleared up, and assuming the reputed Brazilian habitat ot 
C. Makoyanum to be erroneous, we are still without a clue as to whence it 
was imported. The two species are nearly allied, as was originally pointed 
out, but in C. Makoyanum the united lateral sepals are gradually narrowed 
up to the acute point, and the colour is greenish, speckled with brown, but 
in C. Brienianum the lateral sepals do not narrow upwards, and are 
unequally bilobed at the apex, while the colour is straw yellow, with dark 
dull maroon dorsal sepal and petals, and a similar stain at the base of the 
lateral sepals. The lip is yellow in the plant now in bloom. -

IMPORTED Prants.—During the last few weeks large quantities of 
Orchids have been imported. This is the best time to get imported plants 
quickly established, and they give abundance of flowers the first season of 
growing. Dendrobiums, Cattleyas, Lelias, and all the harder-growing 
section should be potted into pots just large enough to get a little fibre 
round and between the roots. Trim the plants and stake them neatly, so 
as to make them look as presentable as possible, and place them in a warm 
moist house, where they will soon commence to grow and root. They 
should be examined and sponged before potting to be safe, though as a 
rule they are clean and free from insect pests. Sometimes in a newly 
imported batch of Cattleyas, traces of Cattleya Fly will be found in the 
young growths just as they are starting into growth, and this can be easily 
detected by the swollen growth, which will be about three times as large 
as usual. This should be cut out at once and burnt, or the whole house 
will become infested. 
OnciDIUM LANCEANUM and PapILio have also been imported this 
season. They are beautiful Orchids and require warm treatment, either at 
the warm end of Cattleya house or in the stove. O. Lanceanum is a 
scented variety. If potted in a compost of Osmunda fibre with a few 
leaves scattered in, they should soon make nice plants, and both are much 
admired when in flower. Both like plenty of moisture during their growing 
season, and a fair amount of sun in order to keep them from making sappy 
growths. 
DENDROBIUM FALCONERI is one of the most beautiful of all the 
Dendrobes, and also one of the most difficult to manage. During the 
growing season this species should be given plenty of air and sun, and it 
will keep in good condition longer if grown on rafts. Plenty of water will 
be required during the growing season. The flowers are large considering 
the size of the bulbs, and they quite hide the plant when freely flowering, 
producing a very beautiful sight.
