About
Castilleja kerryana is a species of flowering plant in the family Orobanchaceae. It is commonly known as Kerry's Indian paintbrush or Kerry's paintbrush. It was formally described in 2013 and so far it is known only from a small population in the state of Montana, in the Northwestern United States.
The first collection of this plant was tentatively identified as a specimen of Castilleja crista-galli, and it is also similar to C. fraterna and C. pulchella. It differs from the latter two in its color and in the shape of its stem and flower corolla.
Where it grows
This plant is known only from the Scapegoat Wilderness, in the Flathead Range of the Rocky Mountains in northern Montana. It has been found only in Cambrian limestone substrates. It grows in thin, rocky soils in krummholz and fellfield habitat. It also grows in moist to dry, gravelly slopes and ridges, scree, and talus. It occurs at 8,000 to 9,000 feet elevation. Its habitat is threatened by climate change, grazing, recreation, and invasive species.
