 both surfaces glabrous, shining, the reticulations rather distinct ; main 

 nerves about 5 pairs, curved, ascending ; length 3*2.5 to 5'5 in., bi'eadth

 branches. Flowers "2 in. long, on pedicels rather shorter than them- 

 selves. Sepals 5, rotund, concave, densely rusty-tomeiitose outside, 

 glabrous inside. Petals 5, several times longer than the sepals, oblong-
