Wildflowers of Southern Arizona
Aster (Asteraceae) family.
Plants 20-110 cm; caudices branched, thick, and woody or rhizomes short, woody. Stems 1-30+, simple, sparsely to densely puberulent proximally to densely so in arrays. Leaves: basal and proximal winged-petiolate-subpetiolate (poorly differentiated), blades to winged petioles; blades oblanceolate, largest to 8 cm, usually smaller, gradually attenuate , margins entire, slightly undulate, sparsely to moderately soft-puberulent, somewhat viscid (stipitate-glands very small); mostly withering by flowering, new rosettes sometimes present; cauline petiolate (petioles 0.5-1 mm), blades (linear) elliptic proximally to (narrowly) lanceolate or ovate distally, largest 50-80 × 15-25 mm, reduced distally and becoming more ovate, 15-20 mm in arrays, margins entire or serrulate. Heads 1-140, not secund, in thyrsi-form-paniculiform arrays, sometimes compact, nearly as wide as tall, and rounded, sometimes appearing almost rounded corymbiform, proximal branches sometimes much elongate, not secund, spreading to ascending. Peduncles 0.5-5(-2.5) mm, densely short hispid-canescent, sparsely to densely stipitate-glandular, ± viscid; bracts small, grading into phyllaries. Involucres broadly campanulate, (3.5-)4-5(-5.5) mm. Phyllaries in 2-3 series, unequal, oblong to linear-lanceolate, acute to attenuate, sparsely to moderately strigose, especially distally, sparsely to densely stipitate-glandular, ± viscid. Ray florets 6-10; laminae ca. 3-5 × 1-2 mm. Disc florets 10-20; corollas 3-4 mm, lobes ca. 1 mm.
