DENDROBIUM BECKLERI. Native of Queensland and New South Wales. 
One of the pencil orchids. Stems long and pendulous and very branching. Leaves 
terete and somewhat quadrangular and about 6 inches long when fully grown. 
In the Spring the plant is covered with its scented blooms. Sepals and petals 
creamy-white—sometimes tinted with green, with pink or reddish-brown long- 
itudinal lines. Lateral sepals about an inch in length, dorsal sepal and the petals 
a little less. The labellum is about as long as the petals and its front lobe is 
rounded, recurved, and gracefully undulated. Sometimes confused with Dend. 
Mortii which resembles it, but has smaller flowers. AS. B3. C4. D2. ES. F13. 
DENDROBIUM BENSONIAE. Native of Moulmein and Siam. 
A popular species with long, slender pseudobulbs, semi-erect as a rule, but with 
a tendency to hang down. Foliage deciduous, the leaves being about two inches 
long and about 3 inch in width. Flowers are produced in late Spring or early 
Summer, according to climatic variations, and appear in twos or threes from the 
nodes on the upper part of the stem. Sepals and petals are white or cream, the 
former being narrow and pointed, the latter broad and rounded. Lip has a pro- 
minent orange yellow centre and two dark blotches at the base. Like a number 
of Dendrobiums, it does not live very long under cultivation. A2. B1. C4. D2.

DENDROBIUM BICAUDATUM. Native of Java. 
An attractive species with long, slender, drooping stems. The leaves grow in pairs 
in parallel rows right along the length of the stem and are ovate, acutely 
pointed and fleshy. They are about 3 inches long and 1 inch across. Racemes 
grow from the upper part of the stem and bear from 2 to § flowers. Lateral 
sepals 3 inch long, petals } inch long, with dorsal sepal and labellum about the 
same length. The general colour is white suffused with pale green lined with 
purple. The petals have a line of fleshy warts from about the middle to the apex, 
something like those of Cypripedium venustum. A4. B1. C1. D2. E2. (ed) FS. 
DENDROBIUM BIGIBBUM. Native of Queensland. 
A beautiful species of varied form which includes the lovely Dend. Patgeciian 
(For the purpose of this table D. Phalaenopsis and its variations will be treated as 
separate species.) Stems up to about 18 inches in height and about $ inch in thick- 
ness. The petals are broad and generally somewhat recurved. The sepals are 
narrower. In colour it ranges from white to a deep carmine purple. The lab- 
ellum is deeper in shade than the petals and sepals, veined with richer purple. The 
throat has usually a white crested ridge—(rarely, this is yellow). The blooms 
vary in size from about 3 inch to 13 inches in diameter. They have a waxy ap- 
pearance and are noted for the double spur formed at the base of the column. 
Variety albo-marginatum.—Similar in shape to the type species, but brighter 
coloured with the tips of the sepals white and with a more or less distinct white 
margin in both sepals and petals.
