erect (terete, striate when dry), branched (usually gland-dotted, farinaceous to puberulent when young).

Leaves

cauline; all or mostly alternate (at flowering);

petiolate or subsessile;

blades obscurely nerved, spatulate to spatulate-obovate or orbiculate-obovate, margins entire, faces gland-dotted (viscid, farinaceous when young).

Involucres

narrowly cylindric, 3.5–5(–6) mm diam.

Receptacles

weakly convex, epaleate.

Florets

usually 5 (aromatic);

corollas pink to purplish, throats ± campanulate, lobes 5, triangular to lance-ovate;

styles: bases not enlarged, glabrous, branches filiform to linear-clavate (distally papillose).

Discussion

Species 1.

The close relationship between Garberia and Liatris has been long recognized. T. Nuttall (1822) included G. heterophylla in Liatris sect. Leptoclinium (as L. fruticosa Nuttall). Garberia is distinct by its shrubby habit and karyotype (L. O. Gaiser 1954).
