Malacothrix glabrata, commonly known as the smooth desert dandelion or desert dandelion, is an annual plant with yellow flowers that appears in western North America.

Description

[edit]

Like other members of its genus, Malacothrix glabrata has a milky sap and daisy-like flower heads. The plants grow to 15 to 40 cm (5 to 15 in) tall. The leaves are 6.5–12.5 cm (2+12–5 in) long, with stringy lobes.[1] The fragrant flower heads are 2.5 to 6.5 cm (1 to 2+12 in) wide,[1] composed of smaller yellow to white strap-like flowers called "ligules".[2] In the center of the flower head may be an orange to red "button", composed of several immature flowers.[3]

Taxonomy

[edit]

It is a dicot in the family Asteraceae.[2] The name "glabrata" refers to the leaves being (nearly) hairless.[2]

Distribution and habitat

[edit]

The species is native to the western United States, excluding much of the Pacific Northwest, and into northern Mexico. It is common to the southwestern deserts of North America.[2]
