A slender, yellowish-green plant 8—12 inches high, from an elongated ovoid bulb. Leaves narrow and grass-like, rough on the margins and midribs, all with sheaths around the stem. Flowers light yellow, ¼ of an inch broad in a compact head 2—3 inches long; stamens exserted, anthers yellow. On open grassy hillsides in the Rockies from Banff to Castle Mountain, flowering in June. [Sidenote: =Stenanthella occidentalis= (A. Gray) Rydb. _Stenthium._] Smooth 12—18 inches high from a bulbous base. Leaves 2—3 from the same root, 8—10 inches long, ½ an inch broad, spreading. Flowers 6—20, greenish-purple, ½ an inch long, open, drooping, in a simple slender head; sepals and petals 3 each, with recurved tips; stamens 6, included. In moist woods throughout the Rockies, growing in moss; the dark green, widely spreading leaves and wand-like stem of drooping bell-like flowers, making a graceful and attractive plant during early summer. [Sidenote: =Tofieldia palustris= Huds. _Scottish Asphodel._] Low with numerous tufted grass-like leaves 1—2 inches long. Flowers 6-parted, minute, greenish-white in a compact oblong head ¼ of an inch long, elongated in fruiting; stamens 6; anthers yellow not exceeding the perianth; head of flowers borne on a slender, smooth stem 3—7 inches high. Abundant throughout the Rockies in damp sandy or gravelly ground, on the flood-plains and banks of rivers and streams and on the gravelly shores of lakes and ponds; flowering in June. [Sidenote: =Tofieldia intermedia= Rydb. _False Asphodel._] Plant with a cluster of grass-like leaves, 3—8 inches long and about ¼ of an inch broad, yellowish-green, from an oblique and chaffy rootstock. Flowers few, less than ¼ of an inch long, pale yellow, 6-parted, on very short pedicels; stamens 6, slightly exserted, with purple anthers; the whole in a compact head about ½ an inch long, on a stem 8—10 inches high, with sticky hairs near the top. [Illustration: _a_ Stenanthella occidentalis (A. Gray) Rydb. Stenanthium. _b_ Clintonia uniflora Kunth. Clintonia. (⅔ Nat.)] Frequent throughout the region at an altitude of 4000 to 5000 feet, in wet open situations with shallow soil; flowering in June. [Sidenote: =Tofieldia occidentalis= S. Wats. _Western False Asphodel._] Similar to the preceding but readily distinguished by its taller stem and more open head of flowers, with longer sepals and pedicels, which are twice as long in each case. In the Selkirks only, but frequent there in the bogs around Roger’s Pass. LILIACEÆ _Lily Family_ Plants with bulbs or corms but never rootstocks; leaves either at the base or in whorls or pairs on the stem; the flowers brightly coloured, frequently large, borne singly or in clusters at the summit of the frequently naked stem, the six parts though usually distinct, sometimes more or less united into a tube; stamens 6; stigma 3-lobed.
