Shoots densely villous. Stems sometimes 6" high with leaves attaining 8" by 3" 

 or more (var. vestita of the Floras, but usually by shady streams and probably the 

 ■effect of environment on the individual), with some 12-14 distinct slightly curved 

 sec. n. nearly reaching then running parallel to margin and shortly hairy on the 

 underside ; in dry places large leaves are usually absent and those on the erect or 

 diffuse flowering stems •5-2'' long, hairy or villous both sides. Bracts herbaceous 

 ■ovate glandular ■25" obtuse. Lowest calyx lobe broadest. Corolla ■12-"25" long, 

 upper lip erect 9f 2 lanceolate or oblong lobes usually pale with red purple lines, 

 lower spreading blue with 3 subequal rounded lobes.

 smaller bracteoles. Sepals 5, subequal or one larger. Corolla long 

 narrow Avitli 5 short patent lobes. Stamens didynamous, included, 

 ifilaments hairy (exc. parvijiora), anther cells 2 separate muticous. 

 Ovary with many ovules in each cell. Capsule small oblong with 

 15-30 globose or cuboid seeds in each cell, hilum a minute hollow, 

 retinacula 0, unripe seeds glandular, finally smooth or with obscure 

 pits. 



Flowers sessile or subsessile in our species.

A diffuse and trailing herb with mostly opposite elliptic or upper 

 oblong obtuse or rounded leaves tapering at the base into a very 

 short petiole, lower attaining 2"75''. Flowers •4-"5" long, mostly 

 axillary but upper in very short or rounded spikes. Bracts and 

 calyx viscid-pubescent. Corolla violet-blue with darker veins, 

 pubescent outside, inside with a ring of red hairs at the base
