Liatris squarrosa (L.) Michx.
- Notes: Liatris squarrosa is shorter than L. pycnostachya (1’ to 1 1/2’ tall), with stiff, spreading hairs on the stem. The leaves are shorter (from 3” by 1/4” to 2” by 3/16”), with stiff hairs on the lower surface and with the leaf bases narrowing abruptly. The inflorescence is shorter (2” to 4”) with fewer heads, although they sometimes overlap. The heads are larger (5/8” long), and the fillaries have long, abrupt, spreading tips (especially the lower) with marginal spreading hairs. The fruits are similar. Flowering is from late July to late August, and fruiting begins in early August. L. squarrosa is infrequent on dry and rocky prairies but does not occur in the Loess Hills.
