nerves and cross veinlets prominent; margins smooth. Peduncles usually 
from the axils of the lower leaves, often exceeding 2 ft. in length, compressed, 
1} in. broad near the base, 1 in. broad at the top. Involucral bracts of firm 
consistence, 4 in. long, 13 in. or more broad at the base, tapering to blunt 
points; the thread-like bractioles about 3 in. long, and 1 line broad, flat, and 
white. Flowers in umbel about 24. Pedicels 1} in. long, the ovary 3-in. 
long. Perianth-tube erect, green, angular, rather slender, 33 to 4 in. long ; 
segments linear, white, 24 in. long, 4 or 5 lines broad; filaments spreading, about 
three-quarters of the length of the segments, purplish in the upper half ; 
anthers narrow-linear, 6 or 7 lines long, pollen yellow. Style erect, one-half 
to three-quarters or slightly exceeding the length of the filaments, purple, or, 
when long, white towards the base. Stigma minutely lobed. Capsules 1 to © 
2 in. in diameter, irregularly globose, on stout pedicels from 1 to 1} in. long, 
the terminal beak prominent, 4 or 5 lines long. Seeds 9, angular, immersed in 
the placenta, varying much in shape and size. 
Hab. : Creeks off Brisbane River. 
As there exists considerable confusion in the nomenclature of the Aus- 
tralian species of this genus, I deem it necessary to publish fresh descriptions, 
drawn up from living plants of the Queensland species, as opportunities offer. 
Two such have already appeared in this Jowrnal—viz., C. brevistylum and C, 
pestilentis.

Order ORCHIDEZ. 
DENDROBIUM, Swartz. — 
D. Armitiz, Bail (n.s.p.) Stems very numerous, arising from a dense mass of 
aerial roots, very slender, scarcely exceeding 1 line diameter and 12 to 18 in. 
high ; the old ones more or less clothed with the torn sheaths of old leaves, so 
much so at times that the nodes appear as if surrounded with a ring of stiff 
hairs. Leaves linear-lanceolate, 2 to 3} in. long, and scarcely 3 lines broad, 
tapering to a very oblique apex, numerous on the young stems and above 
the flowers on the flowering ones. Flowers numerous, lateral, light-pink, 
except the lateral lobes of the labellum, in pairs, the common peduncle very 
short or wanting. Pedicels including ovary 3 lines long, white; the ovary 
yellowish, very short. Sepals linear-lanceolate, about 4 lines long; the spur 
rather long, turned upwards. Petals long as the sepals, but rather narrower. 
Labellum shorter than the other segments, loosely attached to the elongated 
base of the column, 38-lobed, terminal, narrow, acuminate, very light-pink, 
recurved; the calli on the face being long and dense, the part might be termed 
“bearded”; lateral-lobes rather long, very dark-brown, incurved, truncate at 
the end, somewhat tapering at the base, margins entire. Disk white on each 
side of a thick raised dark-yellow midrib, along the sides of which are distant 
thread-like calli. Column very short, with broad lateral wings ending in a 
tooth at the top, white, except the face of the elongated part, which is orange- 
yellow. Anther-lid white. Pollen-masses amber-coloured. 
Hab. : Near Samarai, New Guinea, Miss Armit. The plants brought from whence now
