A beautiful dwarf species of the efarinose series of the Section 
Bella. Two other efarinose species belong to the series— 
P. Bonatiana, Petitm. and P. indobella, Balf. fil. et W. W. Sm. 
From the former—a species only briefly described by Petitmengin 
—it differs by its much smaller size, its bracts, the form of calyx 
and its lobes, the form of the corolla lobes. From the latter by

The discovery of this species furnishes a link connecting the
