prominent palate nearly closing the throat: filaments dilated at their apex: 
style rather shorter than the capsule, thickened below, bent forward, indu-

Low annual herbs with opposite or verticillate, leaves and blue 
pink or variegatéd flowers verticillate or solitary on .ebracteate 
simple pedicels in the axils of the upper leaves. Calyx campan- 
ulate, 5-cleft. Corolla irregular, gibbous or saccate on the upper 
side: the tube short and the limb deeply bilabiate: the upper lip 
2-cleft, the lobes erect or recurved; lower lip larger, 3-lobed the 
lateral lobes spreading or drooping, the middle one cenduplicate 
into a keel-like sack and enclosing the 4, declined stamens and 
filiform style. Filaments filiform, the lower pair inserted higher 
on the corolla than the others, the fifth represented by a gland at 
the base of the corollaon the upper side. Anthers round-reniform 
the 2 cells confluent into one at the apex. Ovules few in the 
cells. Capsule ovate or globose, at first septicical; the valves 
soon cleft in the middle. Seeds amphitropous and peltate, concave 
ventrally. 
* Peduncles deflexed in fruit: seeds terete or nearly so, not margined. 
C. grandiflora Dougl. Lindl. Bot. Reg. t. 1107. Glabrate or minu-

oblong to lanceolate or linear, 10-18 lines long, sessile or short-petioled, 
sparingly and obscurely dentate, usually 3 or 4 in a whorl: peduncles slen- 
der, in fruit an inch or more long and reflexed, usually only 2 or 4, often 
only one and opposite a branch: calyx-lobes lanceolate-subulate, about two 
lines long, longer than the campanulate tube, very acute: corolla about 6 
lines long, strongly declined, the throat a little longer than the lobes, sac-
