Eyebright; Ojo Brillante

Very tiny flower. Probably Euphasia hirtella or E. alpina

Euphrasia species are semi-parasitic on grasses and other plants. Many species are found in alpine or sub-alpine meadows where snow is common. Flowers usually are borne terminally (zygomorphic) and have a lower petal shaped like a lip. This species has white flowers with a yellow mark on the lower petal to act as a guide to pollinating insects.
