at an imperfect whorl 1-2 mm. below the apex. Pedicels about 

 0.5 mm. long. Fruit 2.5 mm. high, 3 mm. wide, more or less dis- 

 tinctly emarginate or subcordate at both ends; intermediate ribs 

 evident, often slightly corky, the dorsal rib acute. 



Differs from the Coastal Plain species (H.verticillata Thunb.), 

 to which it is most closely related, by having petioles minutely 

 hirsute instead of glabrous, by fruit more or less emarginate at 

 both ends, and by having the intermediate ribs often somewhat 

 corky.
