This species appears to differ from G. angustifoUa in its petiolated, thicker, nar- 

 roAver leaves, glabrous above, and its 4-lobed calyx ; from G. augusta in its petiolated 

 thinner leaves, puberulous below, sub divaricately costate nerves, tomentose pedicels, and 

 4-lobed calyx. The leaves are 19 in. long, 3 in. broad, on a petiole 16 lines long : tLe 

 pedicels are 2-2 J in. long.
