182 THE ORCHID REVIEW. 
E. Parkinsoniam, Brassavolas, Oncidum Londesboroughianum, &c. A 
portion of the East Indian house should also be exposed for the same 
purpose, for Vande teres and Hookeriana delight in the sun, also Oncidium 
splendidum, and a few other obstinate growing and flowering sorts. 
Cattleya Warscewiczii (gigas) may now be watered more freely. No 
good purpose is served by keeping them very dry after this date, as those 
that are going to flower will already have the flower sheath formed within 
the young break. The deciduous Calanthes are now becoming strongly 
rooted, and may likewise be watered more freely, but still carefully, as the 
disease which comes in the young foliage in the form of back spots is 
frequently the result of over-watering before the plant has made roots, 
though it is not always due to that. 
Generally speaking, over-watering of any of the plants need not now be 
feared, that is provided the compost they are growing in, as well as the 
plants themselves, are in good condition. The rule should be to water 
when the sphagnum moss is becoming white. Never give a little because 
the plant is not dry enough to thoroughly water, but let it wait until the 
next day. The Mexican Orchids should now be watered during the after- 
noon or evening. The inmates of this house also delight in being syringed 
in the afternoon, when the air is reduced and the roller blinds removed. 
Calanthe veratrifolia and others of the evergreen section are handsome 
and well worth growing, though perhaps not so useful as the deciduous 
kinds. They delight in the temperature of the Intermediate house, and 
should be kept moderatly moist and shady. A good time for repotting is as 
soon as the flowering season is over. They grow best in a compost of good 
fibrous loam and peat in equal parts, intermixed with a little good leaf soil 
and silver sand. It is not a good plan to mix manure with the compost, 
but they may receive a little weak liquid cow manure when nicely rooted, 
as also may Zygopetalum Mackayi, Lycaste Skinneri, Sobralia macrantha, 
Ccelogyne cristata, and Miltonia vexillaria. For other Orchids I am not 
_ an advocate of manure. 
Odontoglossum citrossum having passed out of bloom will now. be 
growing, and may be repotted where necessary; it is a species apt to 
shrivel a good deal from the effect unless exceptional care be taken for a few 
weeks afterwards. I prefer basket culture for it, but it may also be grown 
in pots. The Phalenopsis should now be making some good foliage if 
suspended on the shady side of the hottest house, and kept free from 
insect pests. It is not well to keep them too heavily shaded, nor too 
saturated at the roots, or the leaves will become sappy and the flower 
spikes small and weakly, not to speak of the dreaded spot which may 
appear. Some of the Dendrobiums, and more particularly D. xX 
Ainsworthii, and others of the same parentage, although growing freely, 
generally become more or less spotted on the foliage. This seems rather
