leaves very scabrous above. (See excluded species no. 569, p. 1090) . .G. aspera. 



Capsules globose or nearly so; corollas 15-20 (23) mm long, the upper lobes 



reflexed-spreading; pedicels and branches ascending or somewhat spreading; 



leaves densely scabrous to nearly glabrous above. 



Anthers rather densely white-villous; corolla 15-20 (23) mm long, campanulate, 



its throat relatively broad, the lobes spreading; in older buds the corolla 



broadly rounded, its profile being widely oblong to obovate-oblong; styles
