of the two trees supported the most magnificent col- 
only of this plant I have ever seen and I would give 
much to be able to revisit it at flowering time. The 
host is about four feet or so in diameter at the base, 
and branches into several large limbs some ten feet 
from the ground. These limbs, and most of their 
larger branches, are completely clothed with D. lingui- 
fotme. What a glorious sight it must be in the spring 
when the green mass of the plant would be hidden 
by countless thousands of racemes of creamy white, 
fragrant flowers. Unfortunately, someone chose this 
particular tree to camp near for some time, and used 
its base as a windbreak for the fire, so that now little 
but a shell remains. Some day a strong blow will 
destroy the colony. 
Now to the terrestrials. One sentence in Mr. 
C. T. White’s report on a previous Naturalists’ trip 
to Dunwich twenty-odd years ago is significant. He 
said that Phaius tankecvilliae ( P . grandifolius ) , was 
everywhere abundant in the swamps. Mr. Dunn and 
I walked some thirty odd miles, and searched every 
piece of swampland we could, and found just one 
small pocket containing a few plants. The Phaius 
has paid the price of its beauty and the area is stripped. 
A few plants of Calanthe veratcifolia were seen in one 
spot. This is the very lovely white relative of the 
more regal Phaius. 
Along one shore of the Brown Lake several 
colonies of two species of Pterostylis were seen. It 
is. of course, impossible to determine species unless 
flowers are present, but the leaves of one type sug- 
gested very strongly those of P. nutans. 
In several places beside the roads, small colonies 
of Geodotum pictum were met with. T wo cr three 
plants of a Dipodium were seen. They could have 
been the common D. punctatum or the almost unknown 
yellow D. hamiltonianum or the white D. punctatum 
var. album. Unfortunately none was in flower at 
the time. 
On the slope of one of the hills east of the camp, 
a colony of a species of Caleana was found flourishing 
in a grove of Cypress pine. 
An Acianthus formed very large colonies in sev- 
eral places, once in association with a robust colony
