Common names: Saw-tooth candyleaf
Synonyms: Stevia serrata var. haplopappa B. L. Robinson Stevia serrata var. ivifolia (Willdenow) B. L. Robinson
Treatment appears in FNA Volume 21. Treatment on page 485. Mentioned on page 484.

Perennials, 40–100 cm. Leaves mostly alternate (at least not regularly opposite, crowded, with axillary clusters of smaller leaves); petioles 0; blades (3-nerved) narrowly lanceolate to lance-linear, 1.5–4 cm, margins serrulate. Heads borne in ± congested, compact clusters. Peduncles 0 or 1–4 mm, sessile-glandular, villous-puberulent. Involucres 5–6 (–7) mm. Phyllaries sessile-glandular, sparsely villosulous, apices acute to acuminate. Corollas white or pink, lobes sparsely sessile-glandular, finely villous-hirsute. Pappi usually ± equaling corollas, sometimes coroniform or 0.2n = (22–) 34 (–54) univalents, less often 17 pairs.


Phenology: Flowering (Jul–)Aug–Oct.
Habitat: Roadsides, disturbed sites, oak-grasslands, oak-pine grasslands, and oak, mixed conifer-oak, mixed pine, ponderosa pine-Douglas fir, pine-fir-aspen, spruce-Douglas fir, and fir-hemlock woodlands
Elevation: 1700–2700 m

Discussion

Some collections of Stevia serrata from Cochise and Graham counties, Arizona, were annotated by J. L. Grashoff as “S. serrata > plummerae”; in leaf arrangement and morphology (venation, margin, and shape), they appear to be similar to typical S. serrata from the same area.
