1.5 mm. long; sepals ovate to suborbicular-ovate, 1.5 mm. long, slightly apicu- 
late, ciliolate, rufid-pubescent above at least along midline, not striate; petals 
oblong, 3.5 mm. long, ciliolate below, with obtuse reflexed apex; stamens 3 mm, 
long, the filaments 0.8 mm. long, rather broad, slightly exceeded by the broader 
oblong truncate gland (this free from near the middle), the anthers unappen- 
daged, 1.2 mm, long, the connective scales oval-oblong, 2.2 mm. long, obtuse, en- 
tire or obscurely erose below ; ovary densely hispid-pilose, the placentae 1-ovu-

Type in the U. S. National Herbarium, no. 690300, collected near Gatin, 
Canal Zone, Panama, February 10, 1911, by E. A. Goldman (no. 1864). 
ADDITIONAL SPECIMEN EXAMINED: 
PANAMA: Marraganti and vicinity, altitude 60 meters or less, 1908, Wil- 
liams 1031 (Y). 
Closely related to R. pubipes, but distinguished by its oval connective seales, 
and leaves not puberulous on the veins beneath.
