leaves broadly ovate-acuminate, the largest with a blade 14 cm. 
long, 10 cm. wide, cordate, setulose on the upper face, pubescent- 
setulose below, margins slightly repand-denticulate, the teeth 
terminating in a short stout bristle, 5-7 nerved from the base, 
the opposite one often much smaller; petioles 4-10 cm. long, 
hirsute-pubescent: inflorescence in lax corymbose panicles, that 
are shorter than the leaves and about 6-flowered; calyx becoming 
urceolate when the fruit is mature, 7-10 mm. high, tawny pu- 
bescent; lobes 6, quadrate, hyaline-margined, setulose; exteriorly 
furnished with a linear-lanceolate, setose-tipped appendage of 
equal length: petals 6, broadly obovate, white, 11 mm. long, sta- 
mens 12, 1 cm. long; anthers as long as the filaments: fruit coria- 
ceous, nearly spherical, 6-7 mm. in diameter, 5-celled, adherent to
