III. MITRASA'CME (from ptTpa, mitra, a mitre, and 

 aKfir), akme, a point ; form of capsule). Labill. nov. holl. 1. p. 

 36. t. 49. R. Br. prod. p. 452. According to R. Br. 1. c. 

 Mitrdgyne would be a more applicable name for this genus. 



LIN. SYST. Tetrdndria, Monogynia. Calyx angular, 4- 

 cleft, rarely bifid. Corolla with an angular tube, and a 4- 

 parted limb, deciduous. Stamens 4, equal, inclosed, rarely 

 exserted ; anthers behind. Style bifid at the base. Capsule 

 dehiscing between the divisions of the style. Glabrous or pilose 

 herbs. Leaves opposite, sometimes crowded and radical, with- 

 out any cauline ones ; sometimes connate. Flowers terminal, 

 umbellate, rarely axillary, solitary. Capsule dehiscing at top, 

 not open. According to R. Br. this genus differs from the legi- 

 timate Gentianece a little, but nevertheless it agrees more with 

 E'xacum than with Scrophuldrince.
