Annual. Plant green or purplish, tending to blacken in drying. 

 Stem 4-7 dm. tall, slender, with many ascending-spreading branches, 

 scarcely striate-angled, slightly scabrellous. Leaves opposite, 

 slightly subopposite above, spreading, hnear, entire, acuminate, 

 those of the stem 2.5-3 cm. long, 1-1.5 mm. wide; bracts gradually 

 reduced; leaves somewhat scabrous above. Axillary fascicles 

 strongly developed, shorter than the subtending leaves. Racemes 

 elongated, frequently but one flower of pair developed, 4-10 

 flowered. Pedicels ascending-spreading, slender, filiform, slightly 

 scabrellous, in flower 10-20 mm. long, in fruit reaching at least 

 20-27 mm. long, 1.5-2.5 times the length of the bracts. Calyx- 

 tube 3-3.5 mm. long, broadly campanuate (in flower), scarcely 

 rib-veined, truncate, its lobes 1-1.2 mm. long, lanceolate, acuminate; 

 apex of tube and lobes within densely puberulent. Corolla 23-27 

 mm. long, spreading 21-25 mm. wide, membranous; its tube 15-18 

 mm. long, straight; its anterior lobes 8-9 mm long, posterior 3-4 mm. 

 long, all shghtly rounded to truncate, anterior spreading, posterior 

 scarcely or not arched, flat-extended over stamens and style; 

 externally pubescent, especially distally, within slightly pubescent 

 about bases of filaments, pubescent in line below posterior sinus; 

 lobes all conspicuously cihate; rose-pink, 2 yellow lines and many 

 small diffused purple-red spots within throat anteriorly. Filaments 

 flattened, posterior 5-6 mm. long, anterior 7-8 mm. long, all lanose, 

 very densely so toward apex; anther-cells 3-3.5 mm. long, lanceolate, 

 cuspidate at base, very densely lanose with tortuous white hairs 

 on the valvular surface, glabrous on the sides. Style 12-14 mm. long,
