| Ecology: | Wooded or open, cool mountain slopes and summits; ledges and outcrops on mountains; more northerly. |
| Blooming Period: | Late July into early September |
| Typical Height Range: | 2' to 3' (6 to 9 dm) |
| What to look for in the field: |
The capitulescence
is typically long and narrow, with numerous short branchlets growing either near the top
of the stem or from nodes along the stem. Heads are
relatively large and showy, NOT arranged in one-sided
arrays on
branchlets. Longer-branched plants are infrequent. |
| Stems
are stout and straight, glabrous
below, gradually becoming pubescent
upwards. |
| Leaves
are basally-disposed.
Basal and lower stem leaves
are often present during flowering. They are ovate,
and taper abruptly to long, winged
petioles.
They are nearly heart-shaped, but lack the characteristic and
distinctive "notch"
at the base of the blade. They are sharply toothed and have long,
slender tips. Mid- to upper stem leaves become *gradually* smaller and
narrower upward. They are also ovate, sharply toothed or with fine,
shallow teeth,
and taper to shorter winged petioles. |
|
Involucres
are tall, from 9.5 to 11.5 mm high.** |
