THE ORCHID REVIEW. 369 
a fact which becomes rather inconvenient when the plants have arrived 
at that stage where re-potting or basketing becomes imperative. -I never 
like re-potting Orchids in mid-winter, but here we have an exception to 
the rule, and, as all Orchids succeed best if re-potted just as they 
commence to make new growth, and before the new roots become too 
active, so, therefore, should this particular one be taken in hand now, if 
it requires it. Potting should be performed with the greatest care, not 
breaking or otherwise injuring the roots more than possible, and, after- 
wards, giving the plant a light position in the warmest department, and 
keeping them pretty well supplied with moisture to induce quick growth. 
This species may also be re-potted immediately the new pseudobulbs are 
completed, which will be about May or June, as a fresh batch of new 
roots then make their appearance. I incline, however, to the first-named 
method, because, when repotted in the summer time, the plant has to be 
kept moist, in order that it may become re-established, whereas it should 
then be enjoying a good rest. 
Cattleya’ Percivaliana is now producing its flower buds. One great 
failing of this species is that of the flower-buds not emerging from the 
sheath with reasonable freedom and regularity, as other species do, and, 
frequently, they die immaturely. This is particularly vexing, for when the 
pseudobulb of a Cattleya produces a sheath, in nine cases out of ten, a 
flower-spike follows. Not so, however, with C. Percivaliana; indeed, 
if fifty per cent. appear it is pretty good work. This immature decay of 
the flower-buds is more noticeable in smoky or town districts than in the 
purer air of the country, but in the latter it is also a common feature. 
I have noticed this peculiarity more particularly marked when the plants 
have been subjected to a very low temperature, and when the roots and 
surroundings have been kept too wet and stagnant, and this should be 
avoided. . 
When the deciduous Calanthes have done blooming they should occupy 
a shelf or some such position in intermediate temperature, so that a good 
rest may be assured prior to their again starting into growth. In a 
similar position, and for the same reasons, should be placed the 
Habenarias, which also enjoy a good rest, but which will not stand the 
same long drought as Calanthes, therefore a little water should be given 
now and then to prevent the tubers from becoming too much dried up. 
Odontoglossum crispum is still the favourite amongst Orchid enthusiasts. 
To be really effective when in bloom, it must be grown absolutely well, 
and kept perfectly clean and free from insect pests, especially thrip and 
aphides. Good long spikes of bloom are then to be had, free from the 
blemishes and imperfections caused by the bites of these pests. When so 
seen no doubt O. crispum is a lovely Orchid. It is, nevertheless, oftimes
