Bulbs scaly. =Lilium.= Bulbs corm-like. =Erythronium.= [Sidenote: =Allium recurvatum= Rydb. _Wild Onion, Garlic._] Plant 12—15 inches high with an oblique base from an oblong-ovoid bulb. Leaves narrow and grass-like, 6—8 inches long, thick and half rounded on the back, the old ones persistent and forming a mat at the surface of the ground. Flowers numerous, on slender pedicels, in a nodding terminal head; sepals and petals ¼ of an inch long, elliptic-ovate and obtuse, rosy pink with a darker mid-vein; stamens and styles exserted, anthers pale yellow. Frequent throughout the Rockies on dry grassy or stony slopes and slides; flowering in June. [Illustration: Tofieldia intermedia Rydb. (⅔ Nat.) False Asphodel.] [Illustration: Vagnera stellata (L.) Morong. (¼ Nat.) Star-Flowered Solomon’s Seal.] [Sidenote: =Allium sibericum= L. _Northern Garlic._] Stem 1—2 feet high from a narrowly ovoid bulb, with a single, elongated, round, hollow, basal leaf and 1 or 2 similar leaves on the stem. Flowers numerous in a compact round head; the sepals and petals about ½ an inch long, slender, with a tapering tip, bright rose-purple with a darker mid-vein; stamens much shorter than the perianth segments. Not infrequent in moist open places throughout the Rockies; flowering in July. [Sidenote: =Lilium montanum.= A. Nelson. _Mountain-Lily._] Stem 12—18 inches high, rather stout, from a depressed globose bulb an inch in diameter. Leaves alternate except the uppermost which are in a whorl of 5—7, dark green above, paler beneath, minutely roughened on the edges, lanceolate, tapering but slightly toward the sessile base. Flowers erect usually one, but sometimes several, on a stem; sepals and petals 2½ inches long, somewhat spreading, elliptic-oblong, tapering gradually toward both ends, the base contracted into a claw, which is less than ⅓ the length of the blade; blade reddish-orange on the inner face, paler near the base, which is dotted with numerous purplish-black spots; outer face less brilliant, largely suffused with green; stamens and stigma purplish. Frequent throughout the Rockies on the edges of woods and in the lower river valleys; very abundant in early July in the valley of the Lower Kicking Horse and Columbia rivers from Golden to Donald. [Sidenote: =Erythronium grandiflorum= Pursh. _Snow Lily._] A foot or more high from a deep-rooted, slender, membranous-coated corm. Leaves 2 or occasionally 3, opposite or in a whorl, broadly lanceolate, obtuse, 6—8 inches long, 2—3 inches wide, unequal, dull and glaucous green. Flowers 1—6, nodding, bright yellow, sepals and petals lanceolate 2 inches long, tapering to a slender, strongly reflexed tip; stamens exserted, anthers yellow or purplish-brown.
