wide. The raceme is about 6 inches long, and is flattened and proceeds from 
near the apex of the stems. It bears from 3-5 large flowers. The sepals are 
long (the laterals being slightly more so than the dorsal), twisted, and with the 
apex reflexed. The petals are twice as long as the sepals, have two twists, and 
are pointed. The labellum is large, the front lobe being rounded and pointed in 
front. The sepals and petals are white, more or less suffused with pale green. 
The labellum is white, with rose-pink veins and spots, the throat being tinged 
with greenish-yellow. The chin is coral. Flowers late Spring. Al. B2. Cl.

DENDROBIUM STRIOLATUM. Native of New South Wales to Tasmania. 
One of the terete-leaved species with long branching stems. Leaves straight and 
thick (occasionally curved slightly) up to about 4 inches in length. _ Flowers 
usually in pairs from nodes of the branches. Sepals and petals white with a few 
brownish stripes from the base. Labellum about half as long as the sepals and 
recurved. Flowers in late Spring. AS. B3. C3. D3. E4. or ES. (ea) F13. 
DENDROBIUM STUARTII. Native of Herberton, North Queensland.

It has slender, prominently ribbed stems from 6 to 18 inches high, having a 
number of lanceolate pointed leaves, about 1 inch long, :with purple-suffused 
sheaths. The racemes come from the apex of the stems and usually carry three 
flowers. Sepals and petals yellow with red stripes. The labellum (which is about 
3 an inch in length, oblong and obtuse, the margins being slightly undulated and 
ciliated), is yellow with red radiating veins. The flower is fragrant and about 
1 inch in width. A2. B2. C3. D2. El. (ea) F8. 
DENDROBIUM SUAVISSIMUM. Native of Burma. 
A variety of Dend. chrysotoxum (q.v.) differing from the type in being shorter 
and thicker in habit, the flowers being slightly larger, while the blotch on the 
labellum is purple. It is very strongly scented. 
DENDROBIUM SULCATUM. Native of Khasi, Sikkim. 
A fine species with woody fusiform stems slightly flattened in the upper part 
and very deeply furrowed, growing to a length of between 4 to 12 inches, and 
having a few leaves at the apex. These are broadly oblong, acutely pointed and 
parchment-like in texture. Racemes grow from tops of two-year-old stems 
and are drooping and carry a number of 2 inch flowers with golden yellow sepals 
and petals. The labellum is egg-shaped and concave, the margins turned inwards 
and minutely fimbriated, the disk and the middle of the lip being densely cov- 
ered with fine hairs. It is orange in colour with radiating purple lines at the 
base. It flowers in Summer. Al. B2. C1. D3. El. (ea) FS.
