Definition
Angelica kingii is a species of flowering plant in the family Apiaceae, commonly referred to as King’s angelica. It is a herbaceous perennial native to parts of western North America.
Overview
The species is found primarily in mountainous and subalpine habitats of the Rocky Mountains, including regions of Colorado, New Mexico, Utah, and Arizona. It typically grows in moist meadows, streambanks, and open forest clearings at elevations ranging from approximately 1,800 to 3,200 meters (6,000–10,500 ft). Like other members of the genus Angelica, A. kingii is noted for its tall, erect stems and compound umbels of small white to pale yellow flowers.
Etymology/Origin
The specific epithet kingii honors the American botanist and explorer Clarence King (1842–1901), who made significant contributions to the geological and botanical exploration of the western United States during the 19th century. The genus name Angelica derives from the Latin angelicus, meaning “angelic,” a reference historically applied to several species within the genus for their reputed medicinal qualities.
Characteristics
- Growth form: Perennial herb; erect stems can reach heights of 1–2 m (3–6 ft).
- Leaves: Deeply divided, pinnate leaves with lanceolate leaflets; foliage is typically glabrous to lightly hairy.
- Inflorescence: Compound umbels composed of numerous small flowers; each umbel measures several centimeters across.
- Flowers: Actinomorphic, with five white or pale yellow petals; blooming occurs from midsummer to early autumn.
- Fruit: Schizocarpic mericarps characteristic of Apiaceae, each splitting into two one‑seeded segments upon maturity.
- Ecology: The plant provides nectar and pollen for a variety of native insects, including bees and hoverflies. Its seeds are dispersed primarily by gravity and surface water flow.
