A striking plant growing in stony places and on rocky slopes, throughout the Rockies, flowering in June and July. [Sidenote: =Eriogonum ochroleucum= Small. _Yellowish-white Eriogonum._] Tufted from a large rootstock. Leaves white and woolly throughout, densely crowded on the very short stems, elliptic to obovate-spatulate, half an inch or more long, narrowed at the base into slender, frequently spirally-twisted petioles; scapes slender, several, six inches or more high bearing a globular head of pale yellowish-white flowers ³/₁₆ of an inch high. On a moist rocky slope at an elevation of 4500 feet near Glacier, abundant, the plant may occur elsewhere in the region but has not been observed; flowers in June. PORTULACACEÆ _Purslane Family_ Fleshy herbaceous plants, with regular perfect, unsymmetrical flowers; sepals commonly 2; petals 4 or 5, folded together, stamens equal in number to the petals or fewer. [Sidenote: =Claytonia lanceolata= Pursh. _Spring Beauty._] Stem 3—8 inches high from a round corm. Leaves oblong or lanceolate, ½—1½ inches long. Flowers nearly half an inch broad, few to several in a loose head, on slender pedicels; petals notched at the end or almost obcordate, white with pink veins. One of the first plants to appear in spring on the edges of the snow banks, throughout the region, from the lower altitudes up to the alpine summits, flowering throughout the summer according to elevation and condition of the snow. [Illustration: Claytonia lanceolata Pursh. (½ Nat.) Spring Beauty.] [Illustration: Claytonia parvifolia Moc. (½ Nat.) Small-Leaved Spring Beauty.] [Sidenote: =Claytonia parvifolia= Moc. _Small-leaved Spring Beauty._] Stems 6—12 inches high, diffuse, ascending or somewhat reclined or creeping, sometimes reduced to slender naked runners. Leaves fleshy, rhombic-ovate, acute, about half an inch long, contracted at the base, the upper a quarter of an inch long or less. Flowers few and racemose; petals somewhat obcordate ¼ of an inch long, much surpassing the rounded sepals, rose-colour varying to white; propagating freely by bulblet-like offshoots in the axils of the stem leaves, as well as by the usual method. In wet stony places and in the gravelly beds of Alpine brooks, frequent in the Selkirks, flowering in July. CARYOPHYLLACEÆ _Pink Family_ Herbaceous plants, often swollen at the nodes, with opposite entire leaves and perfect or rarely diœcious regular flowers; sepals 4 or 5 persistent, separated or united into a calyx tube; petals equal in number to the sepals or none; stamens twice as many as the sepals or fewer.
