On trees, in dense jungle, far up the Tahan Valley. 
In the live plant the most conspicuous difference between this plant and .D. Serra is 
the pink column, which is white in the commoner species. There are other much more 
important characters to be seen on looking closer into the two, however. Тһе 
pedicels of the flowers are longer, and the column much larger, in D. rhodostele. Тһе 
lip is very different. In 2. Serra the lateral lobes are well developed and upeurved 
so as to meet the column, while the terminal lobe is small and narrow and bilobed, with 
the two parallel oblong lobes narrower than the rest of the lip. In 2. rhodostele the 
lateral lobes are hardly to be traced, the blade of the lip lies flat against the column, 
and the edges are not curved up, while the terminal lobe is broader and rounded. Тһе 
column is broader and thicker, rose-colour instead of white, with a broader flat anther, 
and an oblong instead of ovate stigma.

I also saw the same plant without flowers in the Tahan woods. Тһе flowers are 
white, except the orange callus on the lip, and the veins on the side-lobes, which are

Р I believe this to be the plant intended by Sir Joseph Hooker for D. clavipes, but the 
flowers (in life at least) are more than a quarter of an inch long, and the mid-lobe,
