Description
Species Description - Biennial (1.5-)3.5-7.5(-9) dm tall; stems from a short taproot, sometimes canescent throughout, erect, 1-6, reflexed or spreading hispid-hirsute below, hispid-hirsute and strigose above. Leaves strigose or subappressed hispid-hirsute, generally long ciliate, at least at their bases, the hairs of two different lengths on the adaxial surface, sometimes with conspicuous pustulate bases; basal leaves not persistent, 2-6.5(-8) cm long, 5-10(-12) mm wide, oblanceolate, petiolate, acute; cauline leaves ascending, and mostly long ciliate, at least at the bases, (l-)3-10(-12.5) cm long, (3-)5-10(-15) mm wide, oblanceoate to linear- oblong to lanceolate, the lowermost leaves petiolate, obtuse or acute, gradually reduced upward, the bracts conspicuous throughout the inflorescence. Pedicels 6-8(-20) mm long in fruit. Calyx lobes 1.7-2.1(-2.4) mm long, oblong to oblong-lanceolate, subappressed hirsute-hispid. Corolla limb blue with a white center, (4-)5-8 mm wide, the tube 1.5-2 mm long, equalling to shorter than the calyx lobes. Fornices with appendages evidently papillate-puberulent or papillate, broad as long, the protuberance about 1.5 times as long as broad. Anthers 0.8-0.9 mm long. Nutlets 2.5-3.5 mm long, lance-ovate; dorsal surface verrucose-hispidulous, the intramarginal prickles absent; marginal prickles (1.5-)2-3.5 mm long, slightly connate or distinct to their bases, rarely connate at their bases forming a narrow wing, the prickles generally over 0.5 mm wide at their bases, 4-7 on each side, a long and a short prickle usually alternating. Chromosome number, unknown.

Discussion
Lappula hirsuta Woot. & Standi., Contr. U.S. Natl. Herb. 16: 164. 1913. Hackelia standleyi Brand, Pflanzenr. IV. 252(Heft 97): 121. 1931. nom. nud. Type. NEW MEXICO. Santa Fe County: 9 miles E of Santa Fe, Santa Fe Canyon, July 2, 1897, A. A. & E. Gertrude Heller 3793 (holotype, US 306419!; isotypes, MIN!, MO!). Hackelia hirsuta is restricted in distribution to northcentral New Mexico. It probably is related most closely to H. floribunda but differs from that species by the fornices, spreading inflorescence, and pubescence of somewhat longer and stiffer hairs.
