On rocky banks and along streams at the lower altitudes throughout the Rockies; flowering during July. [Sidenote: =Symphoricarpos pauciflorus= (Robbins) Britton. _Low Snowberry._] A low, spreading, diffusely branched shrub 6—9 inches high. Leaves broadly oval or orbicular, entire, softly hairy, especially along the veins beneath. Flowers about ¼ of an inch long, solitary in the upper axils, and 2 or 3 in the terminal spike; corolla campanulate, 5-lobed, bearded within; berry globose, white, ¼ of an inch in diameter. In rocky places and on wooded slopes throughout the Rockies; flowering in July. [Sidenote: =Lonicera glaucescens= Rydb. _Douglas’s Honeysuckle._] Smooth, more or less shrubby or twining. Leaves smooth above, glaucous and hairy at least on the veins beneath, 1½—2 inches long, papery on the margins, usually only the upper pair connate-perfoliate. Flowers in a short terminal interrupted spike, corolla 1 inch long or less, yellow changing to reddish, slightly hairy without, long-hairy within, the tube rather strongly inflated at the base, the 2-lipped limb shorter than the tube, stamens and style exserted. In rocky places and along river banks throughout the Rockies; flowering during July. [Sidenote: =Lonicera ebractulata= Rydb. _Fly Honeysuckle._] Shrubby, 3—6 feet high with grey bark. Leaves light green, glaucous and hairy beneath, fringed with hairs on the margins, elliptic-ovate or broadly ovate, obtuse, rounded or cordate at the base, rounded at the apex, 1—2½ inches long, ½—1½ inches wide. Flowers in pairs from the axils of the leaves; peduncles about ½ an inch long; corolla light yellow, about ¾ of an inch long, funnel-form, and spurred at the base on the inner side; berry bright red, ¼ of an inch in diameter. In moist woods throughout the region at the lower altitudes; flowering in May and early June. [Sidenote: =Lonicera involucrata= (Richards) Banks. _Involucred Fly Honeysuckle._] A nearly smooth shrub 3—10 feet high. Leaves short-petioled, ovate, oval or obovate, 2—6 inches long, acute or acuminate at the apex, narrowed or rounded at the base, more or less hairy at least when young. Flowers greenish-yellow, 2 or 3 on axillary peduncles, 1—2 inches long, bracts foliaceous, ovate or oval, often cordate, bractlets larger, greenish-yellow, at length turning rich maroon and surrounding the fruit; corolla hairy, funnel-form; the limb nearly equally 5-lobed; stamens and styles slightly exserted; berries separate, globose or oval, nearly black, about ⅓ of an inch in diameter. In rich moist woods and thickets at the lower altitudes throughout the region, inconspicuous when in flower in late June and early July, but especially showy when in fruit, the blue-black berries subtended by the showy maroon bracts, making it a most striking shrub during summer and early autumn.
