Description:

Vernonia proctorii is a small erect shrub which may reach a height of 1.5 meters. The stems and trunk are densely pubescent with silvery uniseriate hairs and with a knobby appearance due to the persistent petiole bases. Leaves are alternate, ovate to orbicular, subsessile or with the petioles appressed to the stem, and from 1.5 to 3.5 cm long and 1.0 to 2.6 cm wide. The upper blade surface is green to olive-green and moderately strigose with scattered glistening globular trichomes. The lower surface is grayish-green, sometimes becoming rusty with age, and densely sericeous. The leaf margins are densely ciliate with silvery hairs. Flowers are borne in terminal clusters of 2 to 5 heads, each approximately 3 mm in length, and bright purple in color. Achenes are from 2 to 3 mm long and with silvery hairs.
