| What
to look for in the field: |
The
capitulescence
is often long and narrow, with numerous very short branchlets
growing from nodes
along the stem. Robust specimens, may have much longer branches,
each containing numerous shorter branchlets. Heads
appear not to be in one-sided arrays
on the shorter branchlets, but are one-sided on longer
branches. Leaves at the nodes
from which branchlets grow tend to be (much) longer than the branchlets. |
Stems
are thin and wiry, sometimes arching, glabrous and
glaucous. |
Basal leaves
are deciduous
by flowering. Stem leaves are lanceolate, often narrowly so,
and taper to long, slender points. They gradually become smaller
upward on the stem and on branches, and are variously toothed or untoothed. |
