MENZIESIA 



parted, persistent Corolla campanulate, 4-6-lobed, the lobes 

 short, recurved, simply imbricated in bud. Stamens 8-12 : fil- 

 aments filiform : anthers oblong, opening by oblique chinks at 

 the top. Capsule subglobose, 4-6-celled. Seeds small, with a 

 firm coat. 



B. empetriformis Gray Proc. Am. Acad, vii, 377. Densely much 

 branched from the base, 1-2 feet nigh, often forming clumps 1-3 feet in 

 diameter: leaves 3-7 lines long, with strongly revolute thickened and 

 rough margins: pedicels several, somewhat umbellate, subtended by 

 foliaceous and rigid bracts: corolla rose-color, 2-4 lines long, campanulate,

8 KALMIA L. Gen. n. 545. 



Shrubs with entire evergreen coriaceous leaves and umbellate 

 clustered or rarely scattered showy flowers. Calyx 5-parted or 

 of 5 sepals, imbricated in the bud. Corolla saucer-shaped, with 

 a short narrow tube, 5-lobed and 10-saccate below the limb, which 

 is strongly 10-carinate in the bud from the pouches upward, the 

 salient keels running to the summit of the lobes and sinuses, the 

 limb imbricated in the bud. Stamens 10 ; the short anthers free 

 and on erect filaments in the early bud, in the full grown bud 

 received in the pouches of the corolla and the filaments bent over 

 as the corolla enlarges and still more when it expands, straight- 

 ening elastically and incurving when disengaged, thereby throw- 

 ing out the pollen. Anther-cells opening by a large pore; some- 

 times extending into a chink. Stigma depressed. Capsule glob- 

 ular, 5-celled, tardily septicidal. Placentas pendulous or porrect 

 from the upper part of the small columella. Seeds with a thin 

 and mostly close coat. 



K. glauca Ait. Hort. Kew. ii, 64, t. 8. Shrub 6-18 inches high: 

 glabrous throughout and mostly glaucous : leaves all opposite, or rarely in 

 threes, almost sessile, ovate to linear-oblong, or appearing narrower by the 

 usually strong revolution of the margins, dark green above, glaucous white 

 beneath, 6-20 lines long: flowers in terminal fascicles, lilac-purple, 6-8 

 lines in diameter ; bracts large ; sepals ovate, scarious-margined, much im- 

 bricated, persistent. In marshes near the coast, Oregon to Alaska and 

 across the Continent. 



Var. microphylla Hook. Fl. ii, 41. Stems 6-12 inches high: leaves 

 oval barely half-inch long: flowers only 2-6 in the clusters, smaller. 

 High mountain marshes, California to Brit. Columbia. 



-H- -*- Buds scaly-strobilaceous; the thin or scarious scales cadu- 

 cous or deciduous. Calyx often much reduced or obsolete. Corolla 

 gamopetalous. Capsule 4~ or 5-valved from apex to base. Seeds 

 mostly scobiform, having the loose coat produced or appendaged at 

 both ends.
