a72 THE ORCHID REVIEW. [Juty, 1916. 
the young growths are from two to three inches long. The flowers of these 
-species are produced on arching or pendulous racemes, and for that reason 
it is preferable to grow the plants in shallow pans, those without holes in 
the sides for choice. The pans must be well drained, and a compost used 
-of equal parts of Ar fibre or osmunda fibre, half-decayed oak leaves, and 
sphagnum moss, all thoroughly mixed together. Pot the plants rather 
‘firmly, and suspend them from the roof of either the Cool or the cool 
Intermediate house. Water must be sparingly applied until the roots have 
fairly entered the new material, when the amount might be slightly 
increased, but the compost must never be allowed to become saturated. 
Plants of O. macranthum that are developing flower spikes should be 
‘supplied liberally with water at the roots whenever they become dry, until 
the flowers are expanded. The inflorescence should be removed soon after 
the flowers are fully developed, as they exhaust the energies of the plants 
very seriously. Those plants which are not flowering may be repotted 
when the young growths are a few inches long and about to push roots. 
Ordinary well-drained flower-pots make suitable receptacles. 
Oncidium leucochilum should be placed at the coolest end of the 
Intermediate house, and be afforded little water at the roots, although 
frequent overhead spraying is beneficial, as the pseudobulbs frequently 
become more or less shrivelled after the flowering period. Repotting 
should be done soon after the new growths have started, employing the 
compost recommended for the other species. Much less drainage will 
suffice for this species than used for many of the others. 
O. Lanceanum, luridum, carthaginense, tetrapetalum, and others of 
the warm section should also be afforded fresh rooting material, should they 
require it. This section may be treated in the same way as the cooler 
section with the exception that these require the temperature of the warmest 
house. 
VANDA TERES.—The flowering period of this species is now over, and 
those that have attained a great length may be reduced by cutting away 
the bottom vortion. They may be grown as single stems, or five or six 
pieces may be placed in six inch pots, keeping each piece at equal distances 
apart. Each stem should be secured to a neat stake, which should be fixed 
in the pot with broken crocks, filling the pots to about three parts of their 
depth, with these and surfacing with freshly gathered sphagnum moss. 
When in full growth these terete-leaved plants should be exposed to direct 
sunshine and treated to copious overhead syringing several times a day, 
using tepid rain water. V. teres, whilst making its growth, delights in an 
abundance of heat, light, and moisture. V. Hookeriana and the hybrid 
Miss Jouquim should be treated in the same manner. Other terete-leaved 
Vandas, such as V. Kimballiana, Watsonii, and Amesiana are growing and
