corollas (4–)5.5–6+ mm.
24–30+ in 3–4+ series, the longer ± lanceolate, (6–)9–11+ mm (l/w = 2.5–5), apices acute, abaxial faces strigose.
at tips of stems.
(3.5–)4–5+ mm, faces hairy, hair tips entire or forked;

Townsendia florifera
J. H. Beaman (1957) considered plants intermediate between Townsendia florifera and T. parryi to be hybrids. Such intermediates occur in Montana (e.g., Jones in 1905 from Gallatin Co. and Suksdorf 282 from Park Co.), outside the known distribution of T. florifera.
