armoise caudée

Habit Biennials, 20–80(–150) cm. Biennials, perennials, or subshrubs (shrubs in A. filifolia); fibrous rooted or taprooted, caudices woody, rhizomes absent.
Stems

usually 1.

wandlike (new stems may sprout from caudices).

Leaves

basal rosettes not persistent (faces green and glabrous or sparsely white-pubescent).

deciduous (persistent in A. aleutica and A. borealis), usually cauline, sometimes basal, not in fascicles.

Involucres

turbinate, 2–3 × 2–3 mm.

Receptacles

epaleate, glabrous.

Florets

peripheral 1–25 pistillate and fertile;

central 3–32 functionally staminate (not setting fruits);

corollas subglobose.

Heads

in arrays 12–30(–35) × 1–8(–12) cm.

disciform.

Discussion

A population of Artemisia campestris found in Massachusetts differs from populations of subsp. caudata by its smaller heads and multiple branched stems. That population is typical of subsp. campestris, formerly believed to be restricted to Europe.
