herbaceous, erect, viscidulous; stem very straight, simple or branched, scabrous; leaves erect, the lowest linear-oblong, obtuse, much-attenuated at base, scabrous and pilose; upper linear, rigid, one-nerved, scabrous and ciliate, flat or involute, the very uppermost broadbased, short and ovato-lanceolate; heads small, in compound corymbs; invol.-scales shorter than the disc, broadly oblong, obtuse, glutinous; ray-fl. very minute, bilabiate; pappus of very few, small, unequal, rough bristles. Stem 1–2f. high, either quite simple, or split into many very erect appressed branches. Lowest leaves (including the long, tapering petiole) 2–3 inches long, spathulate; upper ones 3/4, 1, 1 1/2 inch long, 1–2 lines wide; those of the corymb 1/4– 1/2 in. long, ovato-lanceolate. All parts rough to the touch, exuding gummy matter. Heads minute. The bilabiate corollas of the ray-fl., and few scales of pappus are irregular in the genus, but the habit and other characters are those of Nidorella. Disc-fl. sterile, their anthers scale-tipped, broad; stigmata perfect.—Dr. Sutherland's specimen has rather broader and more acute leaves, but does not otherwise differ.
