76 THE ORCHID REVIEW. [Marcu, 1915. 
large bright yellow fragrant flowers. The plant succeeds well under the 
same atmospheric conditions as that afforded to the Vandas: it will even 
stand the strongest sunshine at any time provided there is a good 
circulation of air in the house. It requires an abundance of water at the 
roots from the time growth commences till the flowers fade. During the 
resting season the plant should still be exposed where it can obtain all the 
sunlight possible, and the compost kept relatively dry. Repotting may be 
undertaken when growth starts afresh, employing a mixture of good fibrous 
loam, sandy peat, and leaf svuil with plenty of small crocks intermixed. 
DENDROBIUMS.—Many Dendrobiums in the same house will now be 
responding to the influence of increased daylight and warmer weather, and 
flower buds, which a few weeks ago seemed to be making but little progress, 
are now in full beauty, whilst new roots and top growth show that the 
resting season is over. Among plants now in flower the species and 
numerous hybrids are making a fine show, and where a fairly representative 
collection of these plants are grown, there will, if the plants are kept in 
a comparatively dry and well ventilated compartment, be many in bloom 
for a long time to come. Such species as D. Bensoniz, nodatum, Parishii, 
thodopterygium, pulchellum, &c., should still be kept on the dry side 
till their flower buds appear. Plants of D. cretaceum, crepidatum, 
primulinum,  Pierardii, lituiflorum, cucullatum, and many others 
whose flower spikes are prominent, will now require more warmth 
than their resting quarters afford, and a more generous treatment. The 
racemose section will soon be pushing out their flower buds, and in order 
to properly develop such the plants must receive a trifle more water at the 
root, and the warmer atmosphere of the Cattleya house will greatly assist 
them. This section, which is evergreen, contains such fine Orchids as D. 
thrysiflorum, densiflorum, Schroederi, Gnffithianum, fimbriatum, Farmeri, 
suavissimum, chrysotonum, &c. 
THUNIAS.—Towards the end of this month it will be necessary to repot 
the Thunias, the principle varieties being T. Marshallii, T. Bensoniz, T- 
candidissima, the rare T. Marshallii alba, and the pretty hybrids T. 
Veitchii and T. Brymeriana. The plants should be shaken out of the 
old compost, and the dead roots shortened to within an inch or two of the 
base. The general and most convenient way where space is limited is to 
plant seven or eight of the strongest stems together in an eight or nine 
inch pot, which should be almost half-filled with crocks, then a layer of turfy 
loam over these, the rest of the space being filled with the compost, which 
Should consist of good fibrous loam, osmunda fibre, and sphagnum moss cut
