This species appears to be dimorphic, as both in the type and in var. pilosum I 
find nda strep at tinaek; one be ariel the corolla-lobes are about 13-19 lin. 
long a.d somewhat ovate in shape, combined with a staminal column 4--§ lin. 
long, with very short anther-wings ; the other with oblong corolla-lobes acai 
2 lin. long, combined with a staminal column 1 lin. long, having very geass 
longer auther-wings. These two forms of flower do not correspond to differen
