 cuneate, coriaceous ; petiole ^-f in. Peduncles 2-4 in. ; pedicels (many of them)

 sometimes a foot long and broad. Peduncle 5-8 in. Corolla large, funnel-bell-shaped, 

 pink ; tube 1 \ in., lobes of the limb triangular blunt. Not seen ; the foregoing 

 copied from Kurz, who supposed this plant to be Ipomcea zeylanica, Gaertn., which 

 does not grow in Burma ; nor will Kurz's description of the fruit suit, which, if 

 correctly described as a 1-seeded berry no bigger than a pea; it may possibly be 

 a Porana.
