III. MITRASA'CME (from jurpa, mitra, a mitre, and 
axun, akme, a point; form of capsule). Labill. nov. holl. 1. p. 
36. t. 49. R. Br. prod. p. 452. According to R. Br. l. c. 
Mitrágyne would be a more applicable name for this genus. 
Lin. syst. Tetréndria, 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 Gentidnee a little, but nevertheless it agrees more with 
E'xacum than with Scrophulárince.
