Carlquistia is a monotypic genus of flowering plants in the aster family containing the single species Carlquistia muirii. Formerly named Raillardiopsis muirii, the plant was reexamined in the 1990s and moved to a new genus of its own, separate from similar and closely related genera, such as Madia.[1] The new genus was named for the botanist Sherwin Carlquist.[1] Common names for the species include Muir's tarplant,[2] Muir's raillardiopsis,[3] and Muir's raillardella.[4]

This plant is related to the silversword alliance of Hawaiian plants.[1][5]

Description

Carlquistia muirii is a rhizomatous perennial herb forming clumps or mats of stems with hairy green pointed leaves up to about 4 centimeters long. Leaves are arranged oppositely on the lower stem, and alternately higher up. The inflorescence is usually made up of a solitary glandular flower head on an erect stalk. The head contains many yellow disc florets and lacks any ray florets. The fruit is a very narrow achene which may exceed one centimeter in length including its pappus of plumelike bristles.

Distribution

This species Carlquistia muirii is endemic to California. It has a disjunct distribution, occurring in the southern Sierra Nevada and on the other western side of the San Joaquin Valley around the Ventana Double Cone in the Santa Lucia Mountains.[6]
