the upper side. The sepals are about 3 mm long; the infundibuliform corolla
has the proper tube about 3.2 cm long, the throat 2 cm long, the lobes 1.5 cm
long; the anthers are 6 mm long, the ovary is slightly hairy, the nectaries are
concrescent into a ring; the hairy seeds are 7 mm long, the brilliant tawny coma
