Discussion:
From P. sodiroi Hoer., apparently its closest ally, the new species differs in having its leaf-blades slightly thicker in texture and with less prominent venation, its pedicels and calyx more slender, its corolla shorter, and its anthers much shorter and essentially ecalcarate. The small flowers and other obvious combinations of characters readily separate P. idalima from other species of this immediate relationship, P. graebneriana Hoer., P. debilis Sleumer, and P. oreogenes Sleumer.
