t16 THE ORCHID REVIEW. [ApPRIL, 1909. 
The tender growths are liable to attacks of thrip, and should be sprayed 
occasionally. Care must be taken not to let the insecticide lodge in the 
young growths, as it will cause them to rot off if left there for any length of 
time. They are very little trouble to grow, and the flowers are curious and 
give beautiful contrasts in colour. 
CATASETUMS need similar treatment, and should be examined as soon 
as the flowers are past. Their curious flowers always attract attention, and 
the powerful scent is admired by some growers. Cattleya-house treatment 
will suit them, and a compost similar to that advised for Chysis. The light 
and air of the Cattleya house ripens the bulbs well, and they will produce 
good flowers, but if grown soft they will not ster flowers, and the leaves 
will spot. 
ANGULOAS, or Cradle ‘Orchids, as they are commonly called, owing to 
the peculiar shape of the flowers, are very curious, and always attract a 
good deal of attention, though one does not often see them exhibited now. 
The more showy hybrids seem to be replacing many of the old species, yet 
in their way many of the latter are more beautiful. A showy flower one 
sees all at once, but with many Orchids the oftener one looks at them the 
more beautiful they seem. These should also be grown in the Cattleya 
house, in a nice sunny position. Care must be taken not to let water lodge 
in the growths when they are just starting, or they soon damp off. They 
like plenty of syringing when further developed, and the water cannot then 
lodge in the growths. A compost of loam and peat suits these, and the 
material should be kept below the rim of the pot, as they like an ample 
supply of water when in full growth, and plenty of sunshine. 
Cycnoches, or Swan Orchids, are also very interesting, and the flowers 
give off a powerful perfume. They are interesting flowers to most people, 
whether Orchid growers or not, as the formation of the flower and the 
resemblance of the column to a swan’s neck always arouses interest. They 
require Cattleya house treatment, and if suspended near the glass will give 
abundance of flowers. They should be potted as soon as they commence.to 
grow, and not after they flower, for the flowers appear after the bulbs are 
made, and then the plants rest for the winter. Plump back bulbs should 
not be removed, as they will often push out spikes, although to look at they 
appear useless. These also like a peat and loam compost, and dea of 
water and syringing in their growing season. 
CyYPRIPEDIUMS which were potted early will be getting nicely rooted 
now, and should be given an ample supply of water and well syringed over- 
head on every fine day. Thrip must be kept in check by fumigating or 
spraying occasionally with insecticide. The C. bellatulum class will need a 
little more water now they are pushing up their buds. This is a most 
difficult class of Cypripede to get on with, but very satisfactory when once
