This species, remarkable for the wide-spreading slender branches of 
the cyme, as well as for the peculiar bracts, is the most common on the 
Uaupés, growing everywhere throughout the forest, though in a very 
seattered manner. The flowers emit a very pleasant odour, not unlike 
that of our Primrose.

With the P. cornuta, from which it scarcely differs except in colour 
. and the want of the appendages to the lobes of the style.
