This plant was included in genus Madia until 1999, when it was separated and a new genus was created for it. The new genus is named for UC Davis botanist Donald Kyhos.[1] RangeKyhosia is native to the mountains of California from the Sierra Nevada north to the Klamath Mountains, where its distribution extends into southern Oregon. It is a plant of mountain meadows and other moist areas such as streambanks.[2]DescriptionKyhosia is a perennial herb which may exceed a meter in height. Its slender stem is bristly and covered in dark-colored, stalked resin glands. The bristly linear or lance-shaped leaves may be up to 30 centimeters long; those occurring oppositely along the stem are sometimes fused together at the bases. Those further up the stem are much smaller and alternately arranged.[2]The inflorescence is made up of one or more flower heads at the top of the stem. Each head has a bell-shaped involucre of bristly, glandular phyllaries at the base, a center of black-tipped yellow disc florets, and a fringe of 8 to 12 golden ray florets roughly 1 centimeter long. The fruit is a club-shaped achene just under a centimeter long; achenes arising from the disc florets have pappi of scales.[2] References1. ^Flora of North America: Kyhosia 2. ^1 2 [https://www.biodiversitylibrary.org/page/641195#page/463/mode/1up B.
