Hulsea nana  


Hulsea nana (Dwarf hulsea) is a characteristic member of the talus flora on volcanoes from Northern California to Washington. The bright yellow aster-like flowers contribute an outstanding display of colour embedded in an otherwise sombre volcanic substrate. The crinkly edged leaves are hairy and sticky with glands. At high elevations (e.g. on Mt Shasta in Northern California), plants tend to be much more hairy. This may help to reflect away harmful ultra violet radiation.
