 with retrorse-spreading to -incurved hairs, and with longer similar 

 gland-tipped hairs. Leaf-blades lanceolate to ovate-lanceolate, 

 slightly bipinnatifid, segments lanceolate, pinnae falcately spread- 

 ing; glandular-hirsute on both surfaces; those of the stem 1.5-1.7 

 cm. long; 6-8 mm. wide, with 5-7 pairs of lateral lobes. Pedicels 

 slender, in flower 6-10 mm. long, in fruit 7-12 mm. long. Calyx 

 glandular-hirsute, its lobes 3-4 mm. long, lanceolate, acute, dentate. 

 Corolla 7.5-8 mm. long; its lobes 5 mm. long, ovate; rounded, 

 spreading, the two posterior united ^ - f their length; externally 

 glandular-tomentose, within pubescent in a ring about the bases 

 of the filaments, but glabrous below posterior sinus, the lobes 

 irregularly ciliate. Filaments 2.5 mm. long, stout, posterior in- 

 curved, dilated and pubescent two-thirds length; anterior straight, 

 less dilated, pubescent one-half length; connectives glabrous, 

 anther-sacs 3 mm. long, linear-oblong, opening one-half length. 

 Capsule 9-12 mm. long, narrowly ovate-acuminate, glandular-tom- 

 entose. Seeds 1-1.2 mm. long, pale-brown, the raised reticulations 

 thin and somewhat wing-like; intrareticular lines very fine, con-
