DENDROBIUM. 225 
Flowers on long, slender scapes, which spring from the 
top of the leafy growths when mature, strong growths 
producing six or more flowers each; width of each flower 
3in.; sepals lance-shaped and pointed; petals as broad 
again, both coloured rosy lilac, with darker veins; lip with 
two arching side lobes and an oblong, pointed front one, 
the back, with the lateral sepals, forming a broad spur; 
colour deep maroon in the throat, paler and striped on 
the front lobe. This plant should be grown on a teak 
block or raft, in the hottest and moistest stove, from 
which it should never be removed, but allowed to rest by 
withholding water. The pseudo-bulbs sometimes die at the 
base, but if they are fastened to blocks and kept moist, 
they will push new growth from the upper joints, and these 
soon develop into flowering plants. A native of North 
Australia, &c.; introduced in 188o.

D. Pierardi.—This is an old easily-grown spring-flowering 
species, with long, pendulous stems, which often attain to 
upwards of 3ft.in length. The leaves are ovate or lance- 
shaped, 3in. to 5in. long, deciduous, and the upper two- 
thirds of the long stems is laden with long-lasting flowers, 
in which the sepals and petals are pale mauve, tinged with 
rose, the broad, flat labellum being primrose-colour, with 
a few purple lines near the base, the upper surface downy. 
It is a common Indian species, growing chiefly upon 
mango-trees, and was introduced to the Calcutta Botanic 
Garden by M. Pierard, whose name it bears. It is cul- 
tivated at Calcutta by tying it on a smooth branch of a 
tree, to which water is constantly conducted by a string 
through a small aperture in a vessel above; so treated, 
it hangs down to the length of 6ft., and is covered with 
flowers, forming one of the most beautiful objects in the
