Carlquistia

Carlquistia is a rare North American 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.[2] Common names for the species include Muir's tarplant,[3] Muir's raillardiopsis,[4] and Muir's raillardella.[5]

This plant is related to the silversword alliance of Hawaiian plants.[2][6]

The genus was named for the American botanist Sherwin Carlquist (1930-).[2] The specific epithet "muirii" honors Scottish-American naturalist, John Muir (1838-1914).[7]

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 but no ray florets. The fruit is a very narrow achene which may exceed one centimeter in length including its pappus of plumelike bristles.[2]

Distribution

This species Carlquistia muirii is endemic to California. It has a discontinuous distribution, occurring in the southern Sierra Nevada (Fresno, Tulare, and Kern Counties) and on the other western side of the San Joaquin Valley around the Ventana Double Cone in the Santa Lucia Mountains of Monterey County.[2][8]

gollark: Which is arguably bad if you're *using* the currency, but means that a shared one is likely to cause politicking/not be adopted anyway.
gollark: A big issue with this is that in these days of modern economic whatever, control of a currency also allows financial hax which governments want to be able to do.
gollark: (And health services still have to prioritize treatments based on cost; they cannot give everyone arbitrarily expensive treatments)
gollark: Government incentives aren't always aligned with those of the people.
gollark: Post-scarcity would be if you could trivially provide it for free.
