described species, which, with a few exceptions, are natives of 
tropical India and the Malayan Islands. hey are soft-wooded, 
suffruticose, twining plants, of an epiphytal habit; their leaves 
are usually thick and coriaceous. Most of the species inhabit 
moist woods, though some grow in exposed places, subject to 
great drought during the tropical dry season. This plant is a 
native of moist woods in Java, and is described as a strong- 
growing species. It requires a temperature suitable for tropical 
Orchids, but less moisture, especially during winter. It is 
adapted for growing against a back wall or for training up 
rafters ; or it may be coiled round a trellis fixed to a pot. Light 
peat soil, mixed with a portion of turfy loam, is suitable, pro- 
vided it be not such as will become stagnant by an excess of 
water. ‘To prevent this, the pot should be well drained with 
potsherds, and pieces of charcoal mixed with the soil. It is 
propagated by cuttings placed in heat.
