Dig deeper at SERNEC, a consortium of southeastern herbaria.

Differs from N. roanensis in its glabrate stems and leaves at least 3-5 lobed. Read more at Vascular Plants of North Carolina.

Additional characters (other than those explicitly used in the key) useful in separating Nabalus roanensis (in the broad sense, including N. cylindricus) from Nabalus altissimus are: phyllary tips usually black (vs. usually green), flowers 5-8 per head (vs. 4-6), and inflorescence usually narrow and thyrsoid (vs. usually conspicuously branched), per Weakley's Flora (2023).
