sunny weather only, and the ventilation well attended to. This is 
important, as otherwise the growth will be sappy and unmatured, resulting 
in ‘‘spot”” and decay in its various forms. Renanthera coccinea is a 
scandant growing species, and, like Vanda teres and Vanda Hookeri, 
should be allowed to ramble and grow in the full glare of the sun. Phaius 
tuberculosus is now starting to grow, and is an Orchid which delights in 
fresh living sphagnum moss, in which the roots will ramble. The pots or 
baskets should be three parts filled with drainage, on which the roots should 
be placed, afterwards filling up level with the rim with moss, intermixed 
with a few lumps of fibrous peat and broken charcoal. Place it in lightly, 
so that the water can_pass through quickly, for this is another Orchid which 
requires frequent supplies of fresh water. It grows best in a somewhat 
shady and moist part of the East Indian house. P. Humblotii and P. 
grandifolius require the same treatment, with the exception that the 
compost may have a larger addition of peat, and the plant given more 
light. Zygopetalums are Orchids of easy culture, and the spring is the 
best time to repot, before the new growths get too far advanced. For such 
species as Z. Mackayi, Z. crinitum, and Z. intermedium, it is usual to mix 
with the peat and moss some lumps of fibrous loam. Crock the pots about 
half full, and pot lightly. Others, such as Z. maxillare and Z. Gautier, 
are sometimes grown on tree fern stems, but I think of the two, basket 
culture is the most successful. Zygopetalums delight in plenty of water 
during the growing season, but during the winter they should be watered 
carefully. They should be grown in the Intermediate house.
