Descr. Root annual. Stem rounded, downy, waved, 
and branched in our cultivated specimens, simple and up- 
right in our native ones. Leaves stalked, pinnated, pinne 
alternate, extremely unequal, oblongo-ovate, some sessile, 
some on petioles, pinnatifid, lobed and cut, the ultimate 
ones almost bipinnatifid: all slightly downy. Peduncles 
lateral and terminal, bearing three to five rather dense, 
corymbose racemes, of bright purplish-blue flowers. Calyx 
lateral, compressed, of five deep, linear-lanceolate, erect 
segments. Corolla broadly campanulate, with a large, 
spreading, five-lobed limb: at the bottom of the tube 
within, are five pairs of oblong, oblique, white, mem- 
branous, convex scales, much resembling the involucres 
of some AspLeNiA, and between each pair a filament of a 
stamen is inserted. Anther small, yellow. Germen ovate, 
very hairy, two-celled, four-seeded: seeds attached to a 
central receptacle.
