THE ORCHID REVIEW. 61 
should be kept dry for the whole of this month, or it will not flower. 
Water enough to keep it plump, say by syringing once a week. It is best 
grown on blocks, letting the new growth ramble. For this species the 
warmth of the Intermediate house is best. 
Miltonia vexillaria is an intermediate species, it is now in full growth, 
but should not on that account be watered too heavily. It is always best 
to keep the plants on the dry side, and to get them well up to the light and 
air. M. Phalenopsis is an Orchid that requires the warmth of the East 
Indian house during winter, and to be suspended near the glass, or it fails 
to bloom. M. Roezli grows well at the dampest end of the same house all 
the year round. M. Warscewiczii is also a heat-loving species, while none 
of them should be allowed to get too cold during winter, or they suffer. 
Among plants offered by auction during the past month I noticed Lelia 
purpurata, Cattleya intermedia, C. Leopoldi, and Lzlio-cattleya x elegans, 
all of which are Intermediate house Orchids. After they have been for 
some time in an upright position on the stage, and the old roots moistened 
occasionally, new roots will begin to push, when they should be potted up 
and treated like established plants. Make well-formed plants by parting 
and replacing the mass if necessary, and do not insert too much of the old 
ball of roots, as in time they become a wet inert mass. 
Vanda ccerulea is another. I recommend this to be grown in the 
Intermediate or Cattleya house during summer, and the East Indian house 
in winter, and like other Vandas it should never be allowed to become very 
dry. Pot in well-drained baskets in sphagnum moss alone. Anguloa 
eburnea and other species, perhaps do better in the Intermediate house 
than in any other, but they will also grow well at the warmest end of the 
cool house. Trichopilias succeed best treated exactly like the Cattleyas. 
Vanda Roxburghii isa lovely Orchid and should be grown in the East Indian 
house. I also note Cattleya x guatemalensis, which should be grown in 
a warm Intermediate house. Epidendrum vitellinum and Odontoglossum 
Rossii are cool Orchids, and the first named should be kept rather dry 
during winter. Lycastes, Maxillarias, and Zygopetalums are Intermediate 
house Orchids, and, like Anguloas, they all require a compost similar to 
that recommended for Cypripediums. Coryanthes Wolfii should be grown 
in a basket suspended in the warmest house. 
The Mexican Lzelias are now over for another season, but they have well 
filled up a gap in the dull time which would otherwise have looked very 
bare. What lovely things some of the white L. anceps are! They appear 
to vary very much, some having small flowers with only one or two of them 
on a spike, while others are very large with generally four flowers. These 
are very handsome, and the flowers are of more substance than the coloured 
forms, and not nearly so susceptible to injury from the fogs. Mexican 
Lelias enjoy a good rest after flowering, and should receive only enough
