434 THE ORCHID REVIEW. [JUNE, 1917. 
treatment after it starts, or it will not develop strong pseudobulbs. Plants 
that are not strong enough to produce flowers should be given a position 
where they receive the maximum of light, so that they may attain flowering 
size as quickly as possible. C. Dowiana and its variety aurea, having now 
started into growth, should also receive generous treatment, so that they 
may build up satisfactory growth. C. Warneri and its hybrids thrive under 
similar conditions to the preceding, and the earliest plants will be producing 
flowers. The different varieties of C. Mossiz and C. Mendelii will be in 
bloom, and make a great display. There will also be many hybrids of the 
Cattleya, Lzliocattleya, Brassocattleya, and Sophrocattleya families in 
flower, and they may be treated as advised for Cattleyas in previous 
numbers. There is no need to treat each hybrid separately, but with the 
original species it is quite different, as they mostly come from different 
localities, and have their own requirements. These plants are as easily 
grown as any others, and are at the present day much better understood 
than formerly ; the great point to be observed is to keep them in a sweet 
and healthy compost, apply water with care, and maintain a sweet and 
buoyant atmosphere at all times. 
THUNIAS are now pushing up their flower scapes, and may be given 
waterings with weak liquid manure. Owing to their short flowering season 
they are not grown as much as formerly. As a means of extending their 
flowering season, it is advisable when the first blooms expand to remove 
them to cooler and drier quarters. 
MILTONIA VEXILLARIA, with its varieties and hybrids, make a wonderful 
display of beautiful flowers during the summer months, and must not be 
overdone with moisture at the root at this season, neither must they suffer 
for the want of it. When the flower spikes are removed, the plants should 
be carefully rested in the Cool house, and watered sparingly until the new 
growths push forth roots, when any necessary repotting can be attended to. 
ODONTOGLOssUMs, OponTIoDAs, and other plants of a similar nature 
will also make a brilliant display in the Cool house, and, speaking generally, 
there is now an abundance of flowers. The plants in bloom are best 
arranged by themselves so that no spray from the syringe or other 
instrument may reach them, as this induces premature decay. 
CyPRIPEDIUMS.—Plants of the C. bellatulum and niveum section that 
have recently flowered, with their hybrids, may have attention as regards 
new rooting material, if required. Well-rooted specimens in good material, 
with room to develop, should not be disturbed. They are best grown in 
pots, with ample drainage. A suitable compost is made up of two parts 
peat fibre and sphagnum moss, with some small pieces of mortar rubble 
added, and all thoroughly mixed together. The plants must be potted 
firmly, and should be elevated close to the glass in a warm Intermediate
