9. Helianthus petiolaris Nuttall, J. Acad. Nat. Sci. Philadelphia. 2: 115. 1821.

Prairie sunflower

Annuals, 40—200 cm. Stems erect, usually densely canescent, hispid, or strigillose, rarely ± hirsute or glabrate. Leaves mostly cauline; mostly alternate; petioles 2—4 cm; blades (often bluish green) lanceolate to deltate-ovate or ovate, 4—15 × 1—8 cm, bases subcordate or truncate to cuneate, margins entire or ± serrate, abaxial faces strigose, sparsely to densely, or not at all, gland-dotted. Heads 1—5. Peduncles 4—15(—40) cm. Involucres ± hemispheric, 10—24 mm diam. Phyllaries 14—25, lance-linear to lanceolate to lance-ovate, 10—14 × 1—4(—5) mm, (margins sometimes ciliate) apices short-attenuate, abaxial faces usually hispidulous, rarely sparsely hirsute to glabrate. Paleae 4.5—7.5 mm, 3-toothed, middle teeth ± ciliate or bearded, hairs whitish, 0.5—0.7 mm. Ray florets 10—30; laminae 15—20 mm. Disc florets 50—100+; corollas 4.5—6 mm, lobes usually reddish, rarely yellow; anthers reddish to purplish, appendages purplish (style branches reddish). Cypselae 3—4.5 mm, ± villous; pappi of 2 aristate scales 1.5—3 mm plus 0—2 erose scales 0.3—0.5 mm. 2 n = 34.

Subspecies 2 (2 in the flora): w North America.

Helianthus petiolaris is adventive beyond western North America.

A third subspecies has yet to be named at that rank in Helianthus petiolaris ; it has been called H. petiolaris var. canescens A. Gray. It differs in having stems, leaves, and phyllaries densely canescent and abaxial faces of leaves densely gland-dotted. It is additionally characterized by peduncles usually ebracteate, phyllaries 1—2 mm wide, disc corolla throats gradually narrowed distal to slight, not densely hairy basal bulges, and 2 n = 34. It flowers late spring through late summer and grows on sandy soils in open areas at (10—)1000—2300 m in Arizona, California, Nevada, New Mexico, and Texas and in Mexico. It was treated as H. niveus (Bentham) Brandegee subsp. canescens (A. Gray) Heiser by C. B. Heiser et al. (1969); molecular and morphologic data appear to favor a placement within H. petiolaris .
