exhibited a plant which he had cultivated for some years and which had re- 
warded him with a fine display of bloom. After many experiments Mr. Smith 
found that, in Brisbane at least, the best method is to grow the plant out in the 
full sunshine and give it ample water throughout the year. Growing as it does 
on the mangroves in the vicinity of Johnstone River, North Queensland, it lives 
in one of the warmest and moistest parts of Queensland. It will be necessary, 
therefore, to select a spot where cold winds are blocked, and where the maxi- 
mum of sunlight will strike the plant. Water throughout the year, but in 
Winter time select fine, clear, sunny mornings for the purpose. Al. Bl. Cl.

Note. Possibly shredded mangrove bark would serve as an acceptable compost for 
this species. I intended trying this experiment with a very sick specimen given 
me by a disappointed grower—but the plant was dead before I succeeded in get- 
ting the bark. (I'll try anything once!) 
DENDROBIUM TOKAI. Native of Fiji, etc. 
A hardy species with tall (about 3 feet), erect, terete, yellow stems clothed with 
deciduous oblong-obtuse leaves from 3 to 6 inches long, and from 1 to 14 inches 
wide. The racemes are from 8 to 12 inches long and carry numerous large 
flowers fairly densely placed on pedicels of varying lengths in a series of rings 
round the scapes. They are about 3 inches across (when expanded), but the 
sepals are only 3 inch in width, with the petals narrower. They are straw 
coloured. The labellum is an inch in length, and 2 inches wide in the front of 
the middle lobe. The margins are slightly undulated. In colour it is a dirty 
white, veined with purple. Al. Bl. C1. D2. El (ea) F2. 
Var. crassinerve. Differs from the type in having shorter and wider leaves. The 
middle lobe is narrow and acute with thick fleshy elevated lines in the disk—the 
sepals and petals being yellow. 
DENDROBIUM TOMOHONENSE. Native of Tomohon—Celebes, 
An interesting species, somewhat akin to Dendrobiums macrophyllum and atro- 
violaceum. Stems in clusters, rather slender, somewhat fusiform, yellow and 
smooth. They are topped with two broadly oblong, slightly pointed, leathery 
leaves from 34 to 6 inches long and 1} to 24 inches wide. Racemes from the 
top of the stem carrying a few fair sized flowers with a large graceful labellum. 
The scented flowers have yellowish-brown sepals and petals, the labellum being 
pale green, striped with purple. Flowers in Summer. A2. Bl. C2. D2. El.

DENDROBIUM TORTILE (LINDLEY). Native of Malaya, Burma, etc. 
A pretty species with clustered fusiform stems, somewhat flattened in the upper 
part. They are rather twisted and are clothed at the top with a number of narrow, 
oblong, deciduous leaves about 3 inches long. The racemes are short and grow 
from the nodes on the upper part of the leafless stems. They carry two large 
and handsome flowers not unlike those of Dend. primulinum. The sepals and
