The places where they are most abundant usually are called "Camas prairies," and they form a feature of Eastern Oregon and Idaho. They are also plentiful in Western Oregon. The flowering season is about the middle of May, near the Lower Columbia. There are several species of the camas, one of which is poisonous, as noticed above.
It would be impossible to any but a thorough botanist to give a complete list of the flowering plants native to this country. We shall, therefore, briefly notice those which are most common, and which we have had an opportunity of observing. Commencing with the spring, we have the purple iris; mimulus luteus (yellow); yellow lily (Golden Erythronium); white, blue, purple, and yellow lupines; wild pea (Vicia); white daisy; California yellow poppy (Oenothera Biennis); pink oenothera; verbena; brodiea, belonging to the family of Camas—two varieties—both purple, one of them very beautiful, found near Albany; silene, commonly called a pink, very elegant; tobacco pouch (Cypripedium), white, shaded with gray; Indian pink (Castelia brevifolia), scarlet, or orange red; shooting star (Dodecathem media), several colors; larkspur; flax flower (Linum); boys and girls (Cyno Glissum), pink and blue on the same stem; orange lily (Lilium Canadense); red ear-drop (Delphinium nudicaule) white dew-bell (Cyclobothra alba); red columbine; Lilium Washingtonium, the great white lily of the Wallamet Valley; pink convolvulus; golden coreopsis; Phlox, Clarkia; Anemone; sunflower; golden red; (Salidago); aster; dicentra, white and scarlet; Collomia grandiflora, salmon color; Dichelostona congesta (poison camas), purple; Hesperoscardum grandiflora, a white flower, marked with green, very delicate; hossackia bi-color,
