recommended for Phaius.

PHAIUS. The cultural requirements of these are 
a stove temperature, with highly humid conditions of the 
atmosphere while growing. During the resting season 
only sufficient moisture will be required to retain a plamp 
and desirable condition of the pseudo-bulbs. The potting 
compost should consist of fibrous loam and peat, to 
which may be added a liberal amount of sphagnum, and 
sufficient rough sand or broken crocks to keep it porous. 
The drainage should be clean and ample. Care must be 
taken to keep the plants free from Thrips and Scale by 
fumigating and sponging the leaves at regular intervals. 
To the species and varieties described on p. 90, Vol. IIT., 
the following should be added: 
P. albus giganteus (gigantic). jl. larger than in the type; 
sepals and petals pure white; lip golden-yellow. 1896, 
P. Bernaysii is, according to the Kew authorities, a variety 
of P, Blume. 
P. bicolor (two-coloured).*, /l., sepals and petals reddish-brown ; 
side lobes of the lip rose-coloured and folded over the column, 
the front lobe being yellowish-white, flushed with rose. Ceylon, 
1837. An ornamental species which Sir J. D. Hooker regards 
as synonymous with P. Wallichii. (B. M. 4078.) 
P. b. Oweniz (Mrs. Owen's) is a fine, dark-coloured form of it. 
1894. 
P. Blumei (Blume’s). jl., sepals very acuminate; lip two- 
crested within, the limb semi-trilobed, the middle lobe 
largest, undulated. Java (grown in gardens). Closely allied 
to P. grandifolius. (R. G. 1865, t. 464.)

much in colour. The following are some of the chief forms:

P. Brymerianus (Brymer’s). jl. large, disposed in terminal, 
drooping heads; sepals and petals white; lip yellow, with

yellow on the two-lobed spur, truncate or almost two-lobed 
at the end, with a thick, callous line passing downwards along
