| What
to look for in the field: |
The
capitulescence, which may be either
corymb-shaped or
panicle-shaped,
tends to be more or less compact, limited to the upper 1/4 of the stem.
Branches are short to medium-length and densely pubescent. |
Stems
are stout, densely pubescent and rough, mostly straight,
but occasionally bent at the nodes in the capitulescence. |
Basal leaves
are soon deciduous.
Lower and mid-stem leaves are also often deciduous
at flowering. Leaves are lanceolate, untoothed, and
crowded
on stems, with strongly and conspicuously clasping bases. |
Heads
are large, 3.4 to 4.3 cm wide, quite showy, with purple or magenta rays
(rarely pale blue-violet or white). Involucres are broadly
vase-shaped. Phyllaries are long,
spreading to
recurved and long-pointed. They
are
also densely glandular.
