The stem bears 1° a few bracts 2° two flowers each of them 
in the axil of a bract and next ordinary leaves. The inflores- 
cence passes consequently to a leafy branch. We call to mind 
the same phenomenon as having been stated by us with D. su- 
perbum Rchb. f. at the time brought from Borneo to Buiten- 
zorg by Mr. Grootines and described p. 78, 2¢ Série, Vol IV of 
this publication.

Habitat New Guinea. 
From a leafy stem which was quite dead at its base, various 
young plants develop at the nodes, as may be often observed, 
and also a raceme of flowers. The lowermost flowers were 
normal, the topmost was lacking. Between these groups we 
found three abnormal flowers, of which two were tetramerous. 
Paired sepals normal, lip small; opposite the lip a petal. Column 
strongly flattened from front to back, top more or less petaloid. 
Anther 0). 
The other flower has a normal structure with the exception 
only of the unpaired sepal having almost the shape of a petal. 
Mr. Smiru thinks it not impossible that the two petals are 
present and grown together with the unpaired sepal.
