Heads 2–10+, (subsesssile) usually clustered. Peduncles relatively terminal and lateral, 0.5–2 cm. Involucres 8–15 mm wide. 2n = 8, 16.


Phenology: Flowering spring–fall.

Discussion

G. L. Nesom (2003) recognized Xanthisma spinulosum var. glaberrium at species level, as it occurs sympatrically with variety spinulosum in the Texas panhandle, where the two taxa behave like biological species; on the eastern plains of Colorado, however, hybridization and autoploidy have been documented (D. P. Hauber 1986).
