AmBoINA, Wakal, Reliquiae Robinsonianae 1630, 1624, November 5 1913, 
at sea level. Flowers in pairs, yellow, the sepals and petals within with 
lilac spots in lines; lip pure white; column whitish-lilac along the margin 
and near the apex. 
This is a close ally of Dendrobium insigne Reichb. f., of new Guinea. 
I have retained it as a species because it is smaller in all its parts than is 
Reichenbach’s species, and especially because the lip lacks the lateral 
lobes. It is, however, not impossible that it will eventually prove to be 
merely a variety of the widely distributed Dendrobiwm insigne Reichb. , 
which is found at low altitudes in New Guinea and the neighboring islands.
