base in front; upper lip erect, 2-lobed; lower lip spreading, 3-lobed,

open. Stamens 4, didynamous, ascending, included; filaments filiform ; 
anther-cells distinct, oblong, parallel. Style filiform; stigma small. 
usually emarginate. Ovules many in each cell. Capsule ovoid or 
globose, dehiscing by a 3-valved pore at the apex of each cell, or 
by 4—10 valve-like teeth, or by circumscissile or valve-like oper- 
cula. Seeds ovoid, wingless, angular or rugose, or discoid and 
surrounded by a membranous wing. — Herbs, more rarely under- 
shrubs. Lower leaves usually opposite, the upper ones nearly always 
alternate, quite entire, dentate or lobed. Flowers axillary or in ter-
