Fruiting calyx in the Egyptian species reflexed. the upper 
tooth broad and sometimes decurrent, the 2 lowest long and pointed, 
the lateral ones shorter, in some other species the teeth all nearly 
equal. Corolla-tube longer than the calyx, gibbous or produced into 
a spur on the upper side; upper lip 3- or 4-lobed, lower lip entire, 
concave, longer than, or rarely rather shorter than the upper one. 
Stamens declinate, free, without any appendage; anther-cells con- 
fluent. Style shortly bifid. Nuts smooth or slightly granular. — 
Herbs, undershrubs, or in species not Egyptian, shrubs. Flowers 
usually numerous, rarely only 6, in false-whorls, often developed 
into loose opposite cymes forming terminal, panicles. 
The genus is widely spread over tropical and subtropical Asia and 
Africa. Species 100—120.
