while at rest, and do not afford heavy waterings until the roots are seen to 
be moving. 
BRAZILIAN ONCIDIUMS.—There are several other Oncidiums, such as 
O. Marshallianum, crispum, concolor, pretextum, in fact all the Brazilian 
species, are liable to become exhausted by flowering: Therefore the spikes 
should be removed from delicate plants as soon as they appear, and on 
strong plants it is a wise precaution to remove the spikes when the flowers 
are fully developed and have been open a reasonable time. With a season’s 
rest, other conditions being favourable, they will regain their strength. In 
the cultivation of Oncidiums, perhaps, present-day Orchid cultivators have 
made less progress than with any other section that comes under their care. 
SOPHRONITIS GRANDIFLORA, having passed out of flower, will now be 
growing freely at the warm end of the Cool house, and may have new 
material given to the roots should it be requisite, using the Cattleya 
compost. They are best grown in shallow pans suspended from the roof. 
CALANTHES.—The deciduous Calanthes that. have become well rooted 
may have more water at the roots, but those that have not made so much 
progress must still have it applied to them with discrimination, as an excess 
at this season ends in disaster. Care should be taken that the water given 
these plants is always of the same temperature as the atmosphere of the 
house in which they are growing. 
VANDA TERES.—This charming Orchid is now in bloom, and as soon as. 
the flowering period is over growth begins, when the work of repotting may 
receive attention. In growing this plant it is advisable to fasten the stems 
to teak, or some other hard wood stakes, to which the clinging roots may 
attach themselves. The stakes must be fixed firmly in the pots, which 
latter must be two-thirds filled with crocks for drainage, the remainder 
being clean sphagnum moss, pressed firmly, as compost. The stakes 
should be of sufficient length to allow for eighteen inches or so of growth. 
They can either be placed singly in pots or otherwise. When several are 
placed in one pot to make specimens sufficient space should be allowed 
between them to allow of a free circulation of air and sunlight. Where 
sufficient plants are grown it is a good practice to plunge the pots in a bed 
of live sphagnum moss, so they appear to be planted out. This Orchid 
will stand as much sun heat, light, and moisture, both at the root and in 
the atmosphere, as any plant; therefore the position chosen for the plants 
should be one where they are fully exposed to the sun’s rays, and be close 
up to the glass in a house that can be closed early in the afternoon, 
sufficiently to raise the temperature to go° or 100° It is quite an aérial- 
rooting species, and very seldom are many live roots found in the pots, 
whilst those that are clinging to the stakes absolutely revel in the strong 
heat and sunshine. On bright days the plants should be frequently
