Species Description - Erect, glabrous perennial 3–10 dm; lfls 5–9, narrow to fairly broad, flat or loosely folded, 10–35 mm; spikes 1–few, the terminal one becoming cylindric, 1.5–6 cm, more than twice as long as thick; bracts (except the lowest) surpassing the cal-lobes in bud and at least equaling them in fl, the oblanceolate body tapering to a caudate-acuminate tip; cal flanked at base by a pair of bracteoles; fls of sect. Kuhnistera, 4–6 mm, white; cal-tube sharply 10-ribbed, glabrous to shortly villous, the lobes finely ciliate; 2n=14. Dry prairies and dry upland woods; Wis. and Ind. to Tenn. and Ala., w. to Alta., Ariz., and n. Mex. June, July. Most of our plants belong to var. candida, as here described. (Petalostemon c.) The more western var. oligophylla (Torr.) Shinners (P. occidentale), with laxer spike (the axis usually partly visible in pressed specimens), somewhat smaller lfls (seldom over 20 mm), often pubescent cal-tube, and more often diffuse stems, barely reaches our range in w. Io. and w. Minn. June, July.
