and other insect pests, mild periodical fumigations with some reliable 
vapourising compound being the best remedy. Before the flower spikes get 
far advanced it is a good practice to thoroughly cleanse the plant with 
some safe solution of insecticide, as this will carry the plants safely through 
the flowering period. 
ADA AURANTIACA.—This unique flowering plant may be repotted as 
soon as its flowers have faded. When grown in quantity its brilliant 
-_orange-coloured inflorescences have a pleasing effect. It succeeds in the 
Cool house, in an ordinary clean fibrous compost. 
OponToGLossums.—Continue to repot any inmates of the Cool house 
as they attain the desired condition of growth. It is safe to repot now, 
especially if the compost is decomposed, keeping them on the dry side until 
the new roots enter the new material freely. These remarks apply also to 
various species and hybrids of Cool house Orchids which commence to 
make their growths at this season. 
GENERAL REMARKS.—No effort should be made to push plants into 
growth. They should be allowed to start of their own free will, as the 
growth will be much finer and better in every way if made when the sun 
has more influence and power.

H. HILDEBRAND.—The Kew Bulletin announces the death of Mr. 
Arthur Helding Hildebrand, C.I.E., who was for over thirty years 
Superintendent and Political Officer of the Southern Shan States, and who 
will be remembered in the horticultural world as the introducer of several 
Orchids and other plants of more than ordinary interest, including the 
remarkable Lonicera Hildebrandiana, Coll. & Hemsl., which he sent to Kew 
in 1893. Probably his best Orchid was Dendrobium Hildebrandii, Rolfe 
(Kew Bull., 1894, p. 182; Bot. Mag., t. 7653), which he sent to Messrs. 
Hugh Low & Co., of Clapton, who forwarded plants to Kew. This is a 
handsome and floriferous species, allied to D. tortile, Lindl., with light 
yellow flowers, or in the case of the variety oculatum with two maroon 
blotches on the disc of the lip. It is a parent of several interesting hybrids, 
including D. Elwesii, D. Ellisii, D. Haywoodie, D. Rallianum, and D. 
Boundii. Among other Orchids sent to Kew by Mr. Hildebrand were 
Bulbophyllum comosum, Coll. & Hemsl. (Bot. Mag., t- 7283), and the 
striking Orchis monoplylla, Rolfe (Bot. Mag., t. 7601), in which the leaf is 
copiously blotched with purple-brown. Mr. Hildebrand retired in March, 
1902, and returned to his English home at Devizes, Wiltshire. He died at 
Puddletown, near Dorchester, at the age of 65.
