May, I912.| THE ORCHID REVIEW. 147 
ANGULOAS.—The species of Anguloa should be potted either immediately 
they commence to grow or directly they have finished blooming. These 
plants succeed in the same compost as the green-leaved Cypripediums, and 
any that are in need of new rooting material may now have attention. A 
shady position in the Cool Intermediate house will answer their requirements 
LycasTes.—Lycaste Skinneri and its varieties that are starting into 
growth should be repotted, if necessary, also other plants of the same genus. 
They will succeed in the same compost and under the same conditions as 
Anguloas, and should be potted in the same manner (much as an ordinary 
stove plant), leaving a good space on the surface for holding water. 
Although moisture-loving plants, they must not be given much water during 
the early stages of growth. 
ZYGOPETALUMS.—The various members of this genus, supply a desirable 
colour amongst Orchid flowers, their blooms being, for the most part, of 
some shade of blue or violet. Z. Perrenoudii is one of the best. They are 
now producing their flower spikes, simultaneously with the young growths. 
It is not advisable to allow the spikes to remain upon the plants for a very 
long period, and as soon as the flowers lose their lustre, it is best to remove 
them. Any plants needing fresh rooting material should receive attention, 
as new roots soon push from the base of the new growths. Zygopetalums 
are impatient of root disturbance, and should not be repotted unless it is 
absolutely necessary. They will succeed in the same compost as the green- 
leaved Cypripediums, and should be grown in a shady position in the 
Intermediate house. } 
OponToGLossums of the grande and Insleayi section require a slightly 
higher temperature than that provided for O. crispum. They are best 
grown during the winter months at the coolest end of the Intermediate 
house, and kept comparatively dry, but during the summer at the warmest 
end of the Odontoglossum house. Many of these Mexican Odontoglossums 
will now have commenced to grow, and when new roots are seen to be 
pushing from the new growths they may have attention as regards repotting, 
should they require it. They will succeed in the same compost as other 
Odontoglossums. This class of Odontoglossum, having thicker leaves, 
will withstand more sunlight than the thin-leaved ones, and, therefore, 
should not be densely shaded, but the other extreme must also be avoided. 
Cympipiums that require repotting may now be done. Such species as 
C. eburneum, Lowianum, and others, with the increasing number of hybrids, 
will thrive at the cool end of the Intermediate house, where they must be 
shaded from direct sunshine. They will succeed in a compost made up of 
equal parts of fibrous peat and loam, with a fair quantity of sphagnum 
moss and coarse silver sand. They should be potted moderately firmly, 
and much like an ordinary plant. C. Devonianum is distinct in its habit
