Species of flowering plant

Allium shevockii, commonly known as Shevock's onion, is a species of flowering plant in the genus Allium. It is endemic to the Sierra Nevada of California, where it grows in rocky, granitic soils.

Description

Allium shevockii is a perennial plant that grows from a bulb and produces a single flowering stalk. The bulb is typically small and covered with a brown, papery tunic. The leaves are narrow, linear, and usually shorter than the flowering stalk.

The inflorescence is an umbel of several flowers, each with six petals that are white to pink in color. The tepals are lanceolate and have a distinct midvein. The stamens are prominent and the ovary is superior.

Distribution and habitat

Allium shevockii is found exclusively in the southern Sierra Nevada of California. It grows in granite outcrops and rocky slopes at elevations between 1,500 and 2,500 meters. The plant is adapted to dry, well-drained soils and is often found in chaparral and woodland habitats.

Ecology

The flowers of Allium shevockii are pollinated by a variety of insects, including bees and butterflies. The plant is adapted to survive in harsh, rocky environments where few other species can thrive.

Conservation

Allium shevockii is considered a species of concern due to its limited distribution and specialized habitat requirements. Conservation efforts focus on protecting its natural habitat from development and other disturbances.
