MALAXIDE JE. DENDROBIEJE. 73 
from an examination of good specimens sent from Ceylon by Mr. Macrae. 
The pollen masses are in reality 4 in number and lie loosely side by side, 
two in each cell of the anther.

I refer this and the succeeding to Polystachya chiefly on account of their 
habit, It is however by no means clear to me what they really are. M. 
Du Petit Thouars figures 2 pollen masses, in this, and he, and M. Ach. 
Richard both find two in P. cultrata. There is also some peculiarity in 
the attachment of the pollen masses to the stigma which requires more 
investigation.
