Packera malmstenii (S. F. Blake ex Tidestrom) Kartesz

Packera malmstenii is poorly known; it has obvious affinities with P. werneriifolia in both morphology and habitat preference. Its herbage tends to be thick and turgid.

Perennials, 8–15+ cm; rhizomatous (rhizomes relatively slender, branched). Stems 1 or 3–5, loosely clustered, glabrous or bases and leaf axils tomentose. Basal leaves (and proximal cauline, relatively thick and turgid) petiolate (petioles sometimes winged); blades elliptic-ovate or suborbiculate to spatulate, 15–25 × 5–20 mm, bases tapering, margins entire or dentate (at apices). Cauline leaves abruptly reduced (becoming sessile, bractlike). Heads 1–2(–4). Peduncles ebracteate, glabrous. Calyculi inconspicuous. Phyllaries 13, cyanic, 8–9 mm, glabrous or loosely tomentose proximally. Ray florets (0) or 8–13; corolla laminae 7–9 mm. Disc florets 35–50+; corolla tubes 2–3 mm, limbs 2.5–3.5 mm. Cypselae 1–2 mm, glabrous; pappi 3–4.5 mm.
