Hulsea algida

Hulsea algida is a species of flowering plant in the daisy family, known by the common name Pacific hulsea or alpine gold. It is native to the western United States.

Description
H. algida is a hairy, glandular perennial herb producing stout erect stems approaching 40 centimeters (16 inches) in height. The dark green leaves are narrow and covered in white hairs, and the edges are wavy and toothed. Most of the leaves occur in a thick patch at the base of the plant, where they can reach 15 cm in length, and some grow from the stems.

Appearing from July to September, the pseudanthium (flower head) is encased in a cup of densely woolly reddish green phyllaries which open to reveal a daisy-like bloom 5-9 cm wide. The center of the head is filled with yellow or orange disc florets and the circumference has up to 60 bright yellow or gold ray florets each about 1 cm long with rounded or toothed tips. The fruit is an achene up to 1 cm long with a pappus which may be longer.

H. nana is similar, but rarely more than 10 cm tall, with a leafless stalk and 21 ray flowers per pseudanthium.

Distribution and habitat
The species is native to California, Oregon, Nevada, Idaho, Montana, and Wyoming. Within California, it grows in the Sierra Nevada and in the White Mountains. It grows between 9500 and 14000 ft in elevation, in alpine and subalpine talus habitats.
