setose

Achenes obovoid or oblong, attached obliquely at or near the base; pappus setose or partly chaffy or none.—Herbs with alternate leaves and single heads.

In Compositae besides the involucre there are frequently chaffy and setose bracts at the base of each flower, and in Dipsacaceae a membranous tube surrounds each flower.

Legs short, rather slender; fore femora somewhat setose beneath.

The body is clothed with long setose cilia which are frequently fully outstretched when the animal is resting, a slight tremor of the large membrane alone indicating vitality.

Back of cell with a broad central band and two narrower bands branching from it on each side; surface of spaces left uncovered by the bands on the back beset with scattered, long setose spines.
