white, delicately tinged with purplish rose, waved and spirally 
twisted (whence the name): the two lateral ones decurrent into 
a distinct emarginate blunt spur. The ip is large, projecting 
forward, ‘conchiform, or rhomboido-obovate, concave, membra- 
nous, slightly unguiculate, pubescent, faintly veined above and 
below, the margin entire, the sides near the base obscurely 
lobed: the co/owr lemon-yellow, with a slight tinge of purple: 
the base streaked with dark purple. The c/aw is occupied by 
a downy ¢wbercle or callus. Column very short, green, decurrent 
to the base of the lip and forming the spur. Anther-case 
purple. W.J. Z. 
Curr. This fine species of Dendrobium belongs to a group 
of the genus characterized by short, somewhat tumid pseudo- 
bulbs. Judging from our plant it appears to be of a rather weakly 
habit; but its beautiful flowers render it interesting in every 
collection of Orchids. Like the greater number of the genus 
it is epiphytal on trees, and, being a native of the hot and moist 
climate of Java, it requires to be grown in the warm Orchideous 
house. An average temperature of 75° in summer and 65° in 
winter will be congenial to it; taking care, during the winter 
months, that it does not suffer from moisture, and shading, or 
placing it in such a position that it does not receive the direct 
rays of the mid-day sun, in summer. ‘'o imitate its epiphytal 
manner of growth, it should be attached to a block of wood sus- 
pended in a nearly horizontal position, or on a sod of compressed 
sphagnum moss. The latter we prefer, on account of its being 
free from the evils arising from the use of wood: the hot and 
moist atmosphere of the Orchideous house soon brings the wood 
into a state of decay, forming a harbour for insects and con- 
genial to the development of Fungi; the mycelium of some 
_ Species of the latter overrunning the surface of the block, 
bringing it into a state ungenial to the roots of the Orchid. Pro- 
bably the best preventative to the growth of fungi is to pre- 
viously char the blocks of wood ; but in time the charring loses 
its virtue ; and another objection to the use of charred blocks is 
their unpleasant appearance to the eye. J. &.
