THE ORCHID REVIEW. 213 
——which, by the way, has been an exceptionally good one, principally due, no 
doubt, to the mild winter—and should now be given a short rest prior to 
starting into growth again, by keeping them rather dry at the root. If not 
treated in this manner new growths will appear immediately the plants have 
bloomed, and thus cause a double exhaustion of the bulbs, also the following 
bulb will not be up to the usual size and strength, but by giving the plant a 
rest it will break stronger and produce better ulterior results. Ada 
aurantica has also flowered, but is still developing its growths, and con- 
sequently should still be watered freely. Oncidium macranthum and others 
of this section are always more or less in a state of activity, and should be 
given water. accordingly. O. crispum, Marshallianum, and allied species 
Should have less applied direct so soon as the spikes are cut, for the same 
reasons as those adduced with reference to Odontoglossums. O. varicosum is 
now beginning to grow, after having enjoyed a rest, and in their case more 
water will soon be needed. The Masdevallias have made excellent progress, 
both in foliage and flower, the latter seldom attaining such richness of colour- 
‘ ing as they have this season. Those of the caudata and Harryana sections 
have now passed out of bloom, but this will make no difference to the 
quantity ot water required, as root action and leaf development are still in 
a vigorous condition. If any of the smaller growing kinds are in material 
that has become sour or worn out, they would be benefited if renovated now, 
though I do not recommend potting these at this season, excepting when 
necessary from the above cause. 
Passing into the warmer division of the Cool section, we find that 
Miltonia vexillaria has only a few isolated representatives in bloom, the 
majority having gone over, M. v. superba, Leopoldi, and Klabochorum 
have yet to bloom, but for all that a general treatment is still possible as 
far as watering is concerned, though in the matter of spraying overhead, 
only those that have flowered should be done. The Pleiones are now fast 
forming their bulbs, and should have every encouragement to assist in the 
development of good, sound bulbs, by giving an abundance of water, 
occasionaliy diluted with liquid from the farmyard, and the leaves kept 
clean and free from red-spider. No doubt the tips will soon begin to decay, 
but as this is natural, no notice should be taken, and not keep continually 
trimming the decayed portion off, with the mistaken idea of enhancing the 
appearance of the plants. Cypripediums of the cooler section, such as 
C. insigne, villosum, Boxallii, and the hosts of hybrids having one or other 
of the above for one of their parents, will need watering almost daily, as 
also will a large number of the warmer growing kinds, always excepting the 
concolor section, Stonei, phiiippinense, Rothschildianum, Parishii, Lowii, 
Haynaldianum, and others of a similar nature. I may mention here that a 
few months ago we hung our plants of C. bellatulum up in the house where
