[POISON OAK—Rhus diversiloba.]

WAKE-ROBIN.

Trillium ovatum, Pursh. Lily Family.

Rootstock.—Thickened. Stem.—Erect; stout; a foot or more high; bearing at summit a whorl of three sessile leaves. Leaves.—Rhomboidal; acuminate; netted-veined; five-nerved; two to six inches long. Flower.—Solitary; pure white, turning to deep rose; peduncle one to three inches long. Sepals.—Three; herbaceous. Petals.—One or two inches long. Stamens.—Six. Ovary.—Three-celled. Stigmas three; sessile. Capsule.—Broadly ovate: six-winged. Hab.—The Coast Ranges, from Santa Cruz to British Columbia.

The wake-robin is in the vanguard of our spring flowers, and a walk into some high, cold cañon while the days are still dark and short will be amply rewarded by the finding of its white and peculiarly pure-looking blossoms standing upon the bank overlooking the streamlet. The blossoms remain unchanged for a time, and then, as they fade, turn to a deep purplish rose-color.

Our wake-robin so closely resembles T. grandiflorum, Salisb., of the Eastern States, that it seems a pity it should have been made into a different species.

BEACH-STRAWBERRY.

Fragaria Chilensis, Ehrhart. Rose Family.

Hab.—The coast, from Alaska to San Francisco and southward.

This beautiful strawberry is found growing near the seashore, where its large, delicious berries are often buried beneath the shifting sand, becoming bleached in color. It sometimes covers acres with its thick, shining, dark-green leaves, among which are sprinkled its large pure-white flowers, an inch or more across.
