the upper joints of both old and new growths. The sepals and petals are pure 
white and are rather narrow and pointed. The lip is spathulate (tongue-like), 
and is white, marked at the base with a number of coppery-red stripes. Flowers 
in early Summer. (Syn. Dend. eburneum). Al. B3. C3. D2. El. (ea) F4. 
DENDROBIUM ERIAEOIDES. Johnstone River, North Queensland. 
A species of botanical interest only, but interesting to those specialising in 
Queensland species. Stems grow in thick masses from a creeping rhizome. They 
are tapering, finger-shaped, erect, with a few pointed and twisted leaves at the 
apex. Racemes short with a few small, dirty brown flowers, with some whitish 
spots in the sepals and petals. AS. B2. C2. D1. El. (ea) F13Z. 
DENDROBIUM ERYTHOPOGON. Native of Borneo. 
Another black-haired species with erect, stout, twelve inch stems, topped with 
a number of dark green, oval, oblong leaves. Racemes are produced from the 
lateral joints on the upper part of the stems and bear five or more rather dingy 
yellowish flowers, each about 2 inches across. The trilobed lip has seven crim- 
son ridges on the disk of the middle lobe, the two external ones being furnished 
with fringes of crimson hairs. The base of the lip between the ridges is tinted 
crimson, also. Al. B1. Cl. D1. El. (ea) F4. 
DENDROBIUM EXIMIUM. Native of Kaiser Wilhelmsland, New Guinea. 
An attractive but rare species, with fusiform extended stems, growing from a 
short rhizome, up to about 2 feet in length, deeply grooved in the upper parts, 
and bearing a few oblong, pointed, leathery leaves at the apex. The racemes are 
short and carry two or three large flowers with long, pale yellow sepals (the dorsal 
being lanceolate and pointed, and the laterals oval and somewhat triangular), 
and white tongue-shaped petals. The labellum is short and trilobed, the laterals 
being erect, the front lobe being wedge-shaped and rounded with a slight depres- 
sion in the front, white with violet spots and blotches. Flowers in Autumn. This 
plant grows in the steamy gorges of the Torricelli Ranges. A2. Bl. C2. D4. El.

DENDROBIUM FALCONERI. Native of Assam. 
A beautiful species, but usually found difficult to cultivate. The stems are very 
long, slender and branching, with prominent nodes. Leaves are scanty, narrow 
and pointed. The flowers are large, and are produced solitarily from the nodes, 
mostly along the older stems. Flowers are from 4 to § inches across, with sepals and 
petals white with deep purple tips. Sepals are oblong and pointed, and the 
petals are oval-shaped with acute points. The labellum is trilobed, the lateral 
lobes being small and the central lobe heart-shaped and acutely pointed. It is 
white, the front deeply purple with a broad orange disk—marked with a purple 
blotch. This plant must be grown under cool conditions, with plenty of dif- 
fused light. It needs copious watering during the summer and a long resting 
period. It is desirable to keep the compost from drying right out during the 
winter months. A4. B3. C3. (modified), D3. E2. (ed) (or ES.) F3.
