errors of watering. In potting Cattleyas use a mixture of Ar fibre and 
osmunda, well chopped and slightly damp. 
Lelia anceps can now also receive like attention, only for this plant I 
prefer the Orchid pans to pots, as it is shallow rooting. 
Among the flowering plants some of the earliest Dendrobiums will. be 
making a grand display, and for decorative purposes they are so useful that 
one wonders why they have been neglected of late in our great collections. 
Imported pieces can now be obtained and grown on, as described in a 
separate article (p. 93), and there are some beautiful hybrids. 
Vanda ccerulea will now be making a fresh start after its winter rest, 
and water will probably be needed every third day. Remove the old moss 
and replace by fresh, and any plants that have become leggy should be cut 
and lowered in the pots, using a little fine-grade osmunda amongst the 
bottom roots. If any plants are removed from their pots, it will be well to 
thoroughly clean them with some approved insecticide, as they are 
subject to scale and mealy bug, which is troublesome to eradicate at any 
other time. 
The above remarks apply with equal force to Renanthera Imschootiana, 
one of the most brilliant Orchids we have, and those who exhibit at summer 
shows know well its value, its long spikes of scarlet blooms shaded with 
yellow being very attractive. In the compost of this plant use a mixture of 
half osmunda and half green sphagnum moss. 
One word of advice to beginners. Never use sphagnum moss which is 
yellow and dead in the potting compost, as it is of no use to the plant ; it 
merely decays and sours the other ingredients. Heads of green living moss 
must alone be used. 
SUGGESTED ADDITION. 
BRASSOCATTLEYA LEEMANNIZ.—By the combination of Cattleya 
Dowiana aurea and Brassavola Digbyana, a hybrid of great beauty has 
been produced, and, although it cannot yet be procured at a low price, is 
thoroughly worth any additional cost, as it is undoubtedly one of the 
triumphs of the hybridist’s art. The flowers are of good size, the sepals 
and petals yellow, and the lip of similar colouring, more or less veined with 
red, and possessing a beautifully fringed edge. It is a good grower, and 
requires at all times a light position, while during the winter months it 
appreciates the extra warmth of the warmest part of the house. It is 
undoubtedly one of the finest of the very handsome Brassavola Digbyana 
crosses, and inherits the good qualities of both parents.

CHONDRORHYNCHA BICOLOR.—This interesting species has at last 
appeared in cultivation, a plant lately sent from Costa Rica by Mr. E. 
Lankester being in flower at Kew. The species was originally described
