Leaves ovate-elliptic, obtuse with shortly mucronate apex and rounded 
base, generally between 6-9 lin. long, 21-5 lin. broad, tomentose like 
the stem; petiole slender, tomentose, 1}—2 lin. long. Flowers small, 
solitary or few in subsessile umbelliform axillary cymes. Bracts minute,

oblong, } lin. long, replaced in the female flower by flattened sterile 
structures. Ovary (small in the male) surrounded by a ring-like dise, 
glabrous except for a few scattered hairs at the apex. Styles connate 
at the base; stigmas hippocrepiform. Capsule globose, about 1} lin. in
