Intermountain Flora
Annual, mostly 1-6 dm tall, finely puberulent or in part subglabrous below, the pubescence appearing longer and glandular or viscid above; plants simple and unbranched, especially when smaller, or often with several or many short or elongate axillary branches when more robust, the main stem and each of the branches terminating in a dense, leafy-bracteate cluster of essentially sessile flowers, that of the main stem the largest; leaves numerous, nearly all alternate, lanceolate to linear, sessile or nearly so, entire, 1-7 cm x 1-15 mm, those subtending the flower clusters often relatively broader than the others; calyx-lobes narrowly triangular, acute, herbaceous, not markedly unequal, 1.5-3 mm long at anthesis, commonly 3-4 mm in fruit; corolla pink or bluish to white, much longer than the calyx, 8-15 mm long, with a slender tube and short (1.5-3mm) lobes; filaments unequally inserted, about 1 mm long or less; locules uniovulate; 2n = 16.
