DIPODIUM ENSIFOLIUM. Native of North Queensland. 
This species has leafy stems about a foot high. The leaves (which are about 6 
inches long) grow in pairs up the stem and are linear-lanceolate, channelled, 
acutely pointed, strongly ruled and prominently ribbed. The racemes (which 
usually come in pairs on the one stem) carry a number of bright pink flowers 
with purplish spots, up to about 14 inches across, 
DIPODIUM PALUDOSUM. Native of Borneo, Cochin China, etc. 
Erect, leafy stems, with pointed linear-lanceolate leaves of a bluish-green colour. 
The scapes come from the axils of the leaves and carry up to a dozen creamy-white 
flowers, prettily spotted with pinkish-purple. Flowers about 15 inches wide. 
DISA 
A large genus of terrestrial orchids, some of the species of which are extremely 
beautiful and well worth experimenting with if the opportunity offers. Consider- 
able difficulty has been experienced in growing them in Europe, but, as the major- 
ity of the desirable species are natives of South Africa, the climatic conditions of 
Queensland should be quite suitable for their culture either in a sunny bushhouse 
or in the garden beds. They like a compost of fibrous peat, well rotted dung, 
leaf-mould and a little sand. Drainage must be good, and plenty of sunlight is 
desirable. Growth commences at the end of winter at which time the tubers start 
to show new roots. The compost must be kept moist from this period until flow- 
ering is finished. Daily spraying is desirable right through the growing period. 
After flowering watering should be diminished, as the plants need a distinct rest, 
but they should never be allowed to dry right out as they are difficult to restore 
to vigour once they go back. 
The flowers appear on spikes from the tip of a tall, well-leaved stem; the leaves 
whose sheaths clasp the stem are lanceolate. Most species are brilliantly coloured, 
and some are of good size. The best are:— 
DISA BARELLI. Variety of D. uniflora. 
Flowers brilliant orange-scarlet, the lip lighter and veined with crimson. 
DISA CERNUA. 
Green and yellow. 
DISA CRASSICORNIS. 
White, spotted deep purple.
