DENDROBIUM TERETIFOLIUM. Native of Eastern Australia. 
A distinctive species with long, pendulous, much branched stems, having solitary, 
terete, tapering, hard cylindrical, fleshy leaf from 4 to 10 inches in length. The 
flowers grow usually singly but sometimes in pairs, on short racemes which spring 
from the branches of the stem. They have sepals and petals about 1 inch in 
length. The labellum is shorter and recurved. The flower is white or creamy, 
the disk being dotted with reddish brown and having a few raised lines. AS.

DENDROBIUM TETRAGONUM. Native of Queensland and New South Wales. 
A strange species with squarish fusiform stems which grow in a cluster from a 
short creeping rhizome. The stems are very slender at the base (particularly 
the Northern variety), and reach a height of 12 inches or more. They are topped 
with two or three oblong, acute persistent leaves. Flowers grow from the top of 
the stems on a raceme bearing 2 or 3 large but delicate and somewhat drab 
flowers. The segments are narrow, long and acutely pointed. They are pale yel- 
low, the sepals being marked with a few red lines. The lip is yellow, striped 
with red. The northern variety is slightly more brightly coloured. Flowers 
are faintly fragrant at mid-day. Blooms in late Spring. A2. B3. C3. D2.

DENDROBIUM THYRSIFLORUM. Native of Burma. (lllustrated.) 
A beautiful and easily grown species of great popularity. The stems are stout and 
tall and club-shaped. Leaves grow at top of stems, usually 3-4, lanceolate-acute. 
Racemes pendulous from the axils of the leaves of the matured stems, and occa- 
sionally from the older stems. They carry a large number of beautiful flowers 
about 24 inches across, the sepals and petals being white and the lip a beautiful 
rich golden yellow. Flowers in late Spring. (Syn. Dendrobium densiflorum var. 
albo-lutea.) Al. B3. C3. D2. El. or E2. (ea) F12. 
Var. Walkerianum. Plant very robust—racemes up to 2 feet in length—carry- 
ing up to 50 blooms. Individual blooms larger than in the type. 
DENDROBIUM TOFFTII. Native of Queensland. 
A rare and rather difficult but lovely species with tall, stout, fusiform stems, 
somewhat compressed, furrowed, and with purplish ribs. Leaves broadly ovate 
with an obtuse, notched apex. The racemes proceed from the upper part of the 
stems and reach a length of about 16 inches. They carry several large flowers, 
something of the nature of Dendrobium stratiotes (the Antelope orchid), the sepals 
being ligulate and obtuse, while the petals are linear and narrow, generally, 
but not always, twisted. The labellum is large and spreading. Sepals and petals 
are white, the labellum being sometimes white with radiating and branching 
purple lines and sometimes purple with radiating and branching mauve lines, in 
all cases the disk is decorated with violet stripes. This plant is very rarely grown 
successfully out of its natural surroundings, but recently Mr. J. Gordon Smith
