Hookedspur Violet
Viola adunca
Violet family (Violaceae)

Hookedspur violets are common, often hidden among grasses and taller plants especially in aspen forests. Many Viola species commonly cover large areas with scores of flowering plants. Flowers, leaves, and stems of plants that grow at 9,000 feet may be two to five times the size of those growing at 12,000 feet. The plant's spur is no bigger than a mouse's nose; the whole plant is a miniaturized work of art. "Adunca" is Latin for "hooked" and probably refers to the spur at the back of the flower.

A perennial plant lives and blooms for many years.

A herb is a plant whose stems die back to the ground in the winter.

throat -- The opening of a flower.

capsule -- a type of simple, dry fruit produced by many species of flowering plants. In most cases the capsule splits apart to release seeds.

Like the teeth on a saw, leaves and other surfaces can have toothed edges.

fruit -- any seed-bearing structure in flowering plants. It is formed from the ovary after flowering.

petiole -- the stalk of a leaf.

alternate -- leaves alternate along the main stem and are attached singly.

alpine -- above the tree line. Thin soil, rocks, short growing season, frost, winter snow.
