 areolate ; flowers hermaphrodite, all fertile ; corolla tubular,

 lanceolate appendages, obtuse and ecaudate at the base ; style- 

 branches short, straight, or slightly curved, somewhat compressed, 

 not tapering, very blunt, but each with deltoid-lanceolate or 

 lanceolate-subulate deciduous appendage at the apex, more or 

 less included ; achene oblong, or obovoid-oblong, not much com- 

 pressed, with about 5 longitudinal ribs or angles and intervening
