Scientific name:
Draba asprella
Range:
Southwest Utah, north Arizona
Habitat:
Pinyon-juniper woodland, plateaus
Leaves:
Ovate, up to 1.5 inches long, with a covering of branched hairs, growing in a dense basal rosette
Draba asprella has a neat appearance; from a tidy rosette of small basal leaves grows an unbranched brown stalk terminating in a compact spherical cluster of small yellow flowers, usually numbering from 30 to 75. Stems are covered by fine hairs (trichomes), some split into 2, 3 or 4 segments. Leaves have a similar covering, but here all or most of the trichomes are 4-rayed. Leaves in the basal rosette may be entirely flat or partially raised.
Flowers have four yellow petals (slightly notched at the tip) and a tubular center containing six yellow stamens and a yellowish-green pistil. Seed pods are green, ovate, finely hairy, and have a short spur at the apex. The plant is found over a relatively small area of north Arizona and southwest Utah.
