Ecology & Habitat

Description

Packera pauciflora is a glabrous, perennial herb with stems that are 15-40 cm high and arising from a simple or branched rootcrown with fibrous roots. The basal leaves are 3-10 cm long and have long petioles and thick, spade-shaped blades with coarsely toothed margins. The alternate stem leaves, some with a pair of basal lobes, become smaller and sessile upward. Usually, 2-6 erect flower heads are borne in a crowded, terminal inflorescence. Each flower head has a single series of reddish-purple, narrow, pointed involucral bracts that are 6-8 mm long. Disk flowers are orange to reddish. Rays are inconspicuous or lacking. The achene has a pappus at its summit.

Diagnostic Characteristics

Packera debilis and P. indecora have more deeply lobed lower leaves and are generally found at lower elevations.

Habitat

This species is found in subalpine to alpine damp meadows or woods at elevations ranging from 0 to 2,700 meters (Trock, 2020).
