Botanical Magazine, t. 4970. 
Var. philippinense.—Pseudo-bulbs almost pendent, from 
3ft. to 5ft. long. Flowers paler, and the segments more 
acute, than in the type. 
D. Bensoniz.—A handsome species, erect in habit, the 
pseudo-bulbs from 1ft. to 2ft. high, terete, as thick as the 
finger, yellowish when mature. Leaves about 2in. long, 
deciduous. Its lovely flowers, which are about 2}in. across, 
are produced in May and June, growing in twos or threes 
on the upper part of the stem; the sepals and petals are 
milk-white ; the lip is white, with an orange centre, and 
ornamented near the base with two large, velvety-black 
blotches. This species is a native of Moulmein, whence 
it was introduced to our gardens in 1866, by Lieut.-Col. 
Benson. It is not easily kept in health after about two 
years’ cultivation. It should be planted in a pot or basket, 
in peat-fibre and sphagnum, and be grown in a hothouse; 
when growth is finished, the plants should be placed in 
an intermediate temperature, and be kept dry.

shaped, with a tongue-like front lobe, deep maroon, with a
