must be taken with regard to such species as C. Stonei, C. Rothschildianum, 
C. levigatum, and others of this section, that water is not allowed to lodge 
in the centre of the growths or axils of the leaves, as this is likely to cause 
them to decay. 
VANDA CG@RULEA.—After a season of rest since passing out of flower, 
plants of Vanda ccerulea have become active at the roots, and the work of 
repotting should be attended to. Plants that have healthy roots and have 
retained their bottom foliage should have the cold compost picked out from 
between the roots and replaced with new, while others that have become 
bare of leaves at the bottom should have portions of the stem cut away to 
below some of the aerial roots and potted up/afresh. The plant should be 
placed as low down in the pot as possible, filling in between the roots with 
clean crocks to three-quarters the depth of the pot, and fill up to the rim 
with a mixture of osmunda-fibre, half decayed oak leaves, and sphagnum- 
moss, pressed moderately firm, and secure each plant to a stout stick. 
Syringe frequently between the plants and on the undersides of the leaves 
during bright weather. The plants should occupy the lightest position in 
the Cattleya or Intermediate house, and be subjected to but little shade. 
VANDA TERES.—This is a very beautiful Orchid that blooms freely at 
this time of the year, and as soon as the plants pass out of flower their 
growing season commences. At this period the work of repotting or 
resurfacing should be done. It is a good practice to grow the plants on 
long upright teak-wood rafts; these should be placed in rather deep pans 
and clean crocks placed around the base and surfaced with two or three 
inches of chopped sphagnum-moss. . The plants will soon attach them- 
selves to the raft as they produce -aerial roots very freely. This Vanda 
revels in heat and moisture, with plenty of syringing overhead during the 
growing season, but when growth is completed it should be placed in the 
Cattleya house and kept rather dry at the roots. 
MaspDEVALLIAS.—Many of the Masdevallias are now in flower, and 
must be protected from all bright sunshine, afforded a cool temperature, 
and kept clear of thrip insects or the foliage will soon be disfigured. To 
keep Masdevallias in a thriving condition they should be repotted every 
two years, and carefully watered at all times. The pretty white flowered 
M. tovarensis is now starting into growth, and any necessary repotting 
should be given attention at this period. 
DENDRoBiuMs.—For a short time after passing out of flower the ever- 
green section of Dendrobiums, such as D. chrysotoxum, D. thyrsiflorum, D. 
densiflorum, and their hybrids, should be kept cool, and the roots 
maintained on the dry side. The necessary repotting should be attended 
to as soon as roots develop from the base of the young growths. These 
plants resent too. frequent root disturbance, and flower much more freely
