Perennials, 1–3 cm (usually ± pulvinate). Stems ± erect; internodes 0.1–1 mm, ± villous. Leaves basal and cauline, ± spatulate to oblanceolate, 3–8 (–18) × 1–2.5 mm (not fleshy), faces ± villous. Heads ± sessile. Involucres ± campanulate, 4–8 mm diam. Phyllaries ca. 26 in 3–4 series, the longer ± lanceolate, 5–8 mm (l/w = 3–5), apices acute, abaxial faces ± strigose to villous. Ray-florets 13–17; corollas white adaxially, laminae 5–8 mm, glabrous abaxially. Disc-florets number unknown; corollas 4 mm. Cypselae 3–4 mm, faces glabrous or glabrate; pappi readily falling, of 15–20 subulate to setiform scales 3–5 mm (± connate basally).


Phenology: Flowering Jul.
Habitat: Rocky slopes
Elevation: 2600 m

Discussion

Of conservation concern.

The type of Townsendia microcephala may prove to be conspecific with that of T. spathulata.

"broader" is not a number.
