Azuay: The eastern Cordillera, 1-8 km. north of the village of Sevilla de Oro, 

 8,000-9,000 ft. dev., July 27-Aug. 12, 1945, Camp E-4597 (TYPE US 1,989,098; 

 dupl. NY) (plant vine-like; leaves deep green above, very pale beneath; hypanthium 

 crimson; base of corolla crimson, the apex white; fruit non-glaucous), Camp 

 E-4379 (vine; leaves deep green and dull above, pale green beneath; pedicels and 

 hypanthium crimson; corolla bas ally deep pink, apically pale pink to white; imma- 

 ture fruit nitid). 



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 combina- 

 tions of characters readily separate P. idalima from other species of this immediate 

 relationship, P. graebneriana Hoer., P. debilis Sleumer, and P. oreogenes Sleumer.
