Encyclopedia
Kyhosia is a monotypic genus of flowering plants in the aster family
containing the single species Kyhosia bolanderi, which is known by the common names Bolander's madia and kyhosia.
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.
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.
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.

Description
Kyhosia 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.The inflorescence
