until the flowers are fully expanded. Those species with thick fleshy leaves, 
of which the beautiful O. Lanceanum may be cited as an example, need 
careful watering at all times, and throughout the growing period a warm 
moist atmosphere is essential. 
CATTLEYAS AND ALLIES.—Many of this family are beginning to root 
freely from the base of the current pseudobulb, and where necessary the 
plants may be repotted. It is best to slightly anticipate the appearance of 
a fresh batch of roots, then there is no fear of injury, and they enter readily 
into the new compost. For large and fully-grown examples osmunda and 
Eo = a 
Ai fibres are generally used, while some growers add a little chopped — i 
sphagnum moss, and a sprinkling of finely-crushed crocks. When the 
operation is completed a copious. watering should be given, and if the 
surroundings are kept moist no more will be needed for several days. The 
newly-potted plants are arranged in batches, then their requirements can be 
given proper attention, while the liability of being over-watered is reduced 
toa minimum, Before placing the plants in their pots all the old useless 
back pseudobulbs can be removed, four behind each lead or growing point 
being ample.. If the variety is a choice one the back bulbs should be employed 
for propagating purposes, either by potting them up or laying them in the 
seed-raising case. until the dormant eyes show signs of swelling. 
CATTLEYA SEEDLINGS, with those of allied genera, should also receive 
attention at this period, and every inducement should be given to help 
them to grow freely, and thus attain flowering size. Those in need of it 
must be provided with fresh compost and larger receptacles. These should 
be filled one-third of their depth with drainage, and the rooting medium is 
made up of osmunda and polypodium fibre and sphagnum moss, in equal 
parts, the whole being cut up rather finely. A sprinkling of partly decayed 
oak leaves may be added where the seedlings are not in a very flourishing 
state. When the weather is bright a light spraying overhead will be 
beneficial, but at present it ought to be done during the earlier part of the 4 
ee 
day. A sharp watch should be kept for insect pests, which are capable of : 
doing much damage. 
GIFT OF OrcHIDs TO KeEw.—We understand that the late Sir Trevor 
Lawrence, by his will, left all his plants to his wife, but expressed a wish 
that she would present to the Royal Gardens at Kew such portions of his — 
collection as she might be advised or might consider to be mainly of 4 
botanical interest, the matter being left entirely to her decision. We 
understand that Lady Lawrence has written to Sir David Prain, the 
Director of Kew Gardens, to say that she has much pleasure in informing 
him of her intention to carry out Sir Trevor’s wishes, and will make the 
necessary arrangements in due course.—Gardeners’ Chronicle.
