Plant Notes:Sticky Rosinweed is a native herbaceous perennial in the Aster family (Asteraceae). It is an Alabama endemic, known only from Bibb County in west central Alabama. All known populations occur on Ketona Dolomite outcrops, the adjacent margins of woods, and rocky margins of streams near the Cahaba River. Sticky Rosinweed is a perennial from a short rhizome. Basal leaves are usually absent at flowering. The stems are from one to six feet in height, and are unbranched below the inflorescence. The stems are round and green in color. Stem leaves are lanceolate or ovate, opposite, and sessile or with short winged petioles. The leaf margins may be entire or toothed. The stems, leaves, and phyllaries are pubescent and glandular. The glands are stalked and amber colored. The entire plant has a resinous feel. Flowers are produced in heads. The heads are arranged in open panicles. Each plant may have from one to thirty heads. Ray and disc flowers are bright yellow. Rays average 8-16 per head. The fruit is an achene. Sticky Rosinweed is listed as a S2 species (typically 6 to 20 occurrences, few remaining individuals, acres, or miles of stream, or factors demonstrably making it very vulnerable in the state), and globally as a G2 species (imperiled globally because of rarity (6 - 20 occurrences, or few remaining acres, or miles of stream) or very vulnerable to extinction throughout its range because of other factors).--A.
