Perennials.  Colony forming from stolons.  Stolons are leafy, ascending at the tips.  Stems are covered with dense, matted (cobwebby) hairs.  Typical height is from 6" to 12".

Inflorescences consist of tight clusters of unisexual flower heads on very short peduncles, located at the tops of stems.

Flower heads are discoid, typically unisexual (pistillate) and fertile.  Florets are narrowly-tubular, with white corollas.  Ray florets are lacking.  Heads with staminate (male) florets are seldom produced; i.e., plants are capable of producing fruit without fertilization.  

Spatula-shaped basal rosette leaves are present throughout the season.  Basal leaves have 3-5 prominent veins.  At maturity, basal leaves approach 3.5 cm in width.  Stem leaves are smaller than basal, linear in shape.  Lower surfaces of leaves are covered with dense, matted hairs.  (See below for distinctions between subspecies.)

Plants of a wide variety of dry, open or wooded sites, including outcrops or ledges on thin soil, and on lawns.  Flowers May.  Native.

Two subspecies are represented in our area:
A. parlinii
(Fernald) ssp. fallax (Greene) R.J. Bayer & Stebbens
A. parlinii
Fernald ssp. parlinii.
