goat would feel at home. In these scrubs the orchids were 
growing in profusion — mainly on low shrubs or bushes, 
the commonest one being known locally as ‘ ‘ Quinine 
Bush” (Specimen No. 1). This is a different plant to 
what is known as Quinine Bush in other parts of Queens- 
land, although similar. The other shrub (Specimen No. 2) 
is very similar in appearance to the Quinine Bush, but 
having the older branches with a smooth mottled bark, 
similar to the Guava stem. The leaves are small, like the 
Quinine Bush. 
The Government Botanist is unable to identify the 
plants without flowering specimens, but says they are 
Myrtaceous plants, like small leaved Eugenia or Mvrtus. 
Occasionally, plants were found growing on rocks, but 
this was the exception rather than the rule. Mostly they 
were growing low down and 1 only saw one plant above 
twenty feet from the ground. A most noticeable fact 
was the thin branches on which the orchids were grow- 
ing; some of them as thin as a pencil. They w’ere very 
plentiful, growing mostly singly, and not in clusters, as 
we sometimes find D. undulatum on rocks. Flowers could 
be seen everywhere (it was the month of April) varying 
in colour from light to dark mauve— the degree of light 
available to the plant making no difference to the colour 
of the flower. No white forms were seen among the thou- 
sands of plants examined. 
While I noticed one raceme with three branches, in- 
variably there was no branching of the raceme. As to 
the size of the plants, observations showed that the 
smallest in flower had pseudo bulbs six inches long, and 
the largest thirty-six inches. The majority, however, were 
small, a plant with bulbs eighteen inches high being a big 
specimen. 
One fact struck me rather forcibly. The only other 
orchid found in these scrubs was the Pencil Orchid (D. 
fceretifolium) and rarely were they found on the same 
tree as D. phalaenopsis. The latter were invariably on 
one of the two bushes previously mentioned, on which I 
never saw D. teretifolium, and only once did I see D. 
phalaenopsis on the same tree which was host to D. tere- 
tifolium. 
Riding back along the creeks I did notice D. 
phalaenopsis on Leichhardt tree, Pandanus sp., Milk 
tree (Alstonia), and also on a tree (probably a Myrtus)
