370 EEICACEAE (heath PAMILY) 



1. Cassiope Mertensiana (Bong.) Don. Hirt. Dichl. PI. 3: 829. 1834. A 

 low Lycopodium-like plant with small imbricate 4-ranked carinate glabrous 

 leaves (2— i mm. long), lateral peduncles, and pinkish bell-shaped corolla.— 

 Mountain sides; Montana to the Pacific States and northward. 



2. PHYLLODOCE Salisb. Mountain Heath 



Low branching shrubs, with small, crowded, linear, obtuse, evergreen leaves. 

 Flowers long-pediceled, nodding, mostly pink, blue, or purple, in terminal 

 umbels. Calyx 5-parted, persistent. Corolla contracted at the throat, 5- 

 toothed. Stamens 10, included; anthers oblong, obtuse, the sacs dehiscent by 

 oblique chinks. Ovary 5-celled; ovules numerous; stigma obscurely 5-lobed, 

 or capitate. Capsule subglobose or globose-oblong. — Bryanthus. 



Corolla campanulate, red; sepals obtuse 1. P. empetriformis. 



Corolla ovoid, yellowish; sepals usually acute . . . . . 2. P. glanduliflora. 



1. Phyllodoce empetriformis (Smith) Don, Edinb. New Phil. Journ. 17: 160. 

 1834. Densely branched from the base, 2-5 dm. high, often forming clumps 

 1 m. in diameter: leaves 6-14 mm. long, with strongly revolute, thickened, and 

 rough margins: pedicels several, somewhat umbellate, minutely glandular, 

 subtended by foliaceous and rigid bracts: corolla rose-color, 5-8 mm. long, 

 campanulate, barely 5-lobed, the lobes much shorter than the tube: stamens 

 included. — In the mountains from Wyoming and Colorado to California and 

 Alaska. 



2. Phyllodoce glanduliflora (Hook.) Coville, Mazama 1 : 196. 1897. Stems 

 rather rigid, fastigiately branched, 1-3 dm. high: leaves numerous and 

 crowded but somewhat spreading, linear-oblong, obtuse, 6-12 mm. long, thick, 

 with a white line through the center below and a deep furrow above, narrowed 

 at base to a short petiole, the margins thick and scabrous: pedicels 15-25 mm. 

 long, glandular-hirsute: sepals lanceolate, acutish to acuminate, 4 mm. long, 

 glandular-hirsute: corolla yellowish, ovoid, 3^ lines long, the short lobes 

 glabrous. — On rocky banks and cliffs near perpetual snow; Oregon to Alaska 

 and the Rocky Mountains. 



2a. Phyllodoce glanduliflora intermedia (Hook.) A. Nels. Probably a hy- 

 brid between the two foregoing and hence variable, but usually with yellowish 

 or pale red corolla, moderately glandular, and sepals either obtuse or acute. 

 [P. intermedia (Hook.) Rydb. Mem. N. Y. Bot. Card. 1: 298. 1900; P. hy- 

 brida Rydb. 1. c. 299.]— The two species and the hybrid frequently occur near 

 each other. 



3. MENZIESIA Smith 



Shrubs with alternate deciduous leaves and small mostly dull-colored flow- 

 ers on nodding pedicels. Calyx bristly-hirsute, usually 4-lobed. Corolla glob- 

 ular-urceolate to cylindraceous, 4-toothed or lobed. Stamens not exserted, 

 usually 8; filaments subulate; anthers mostly linear-sagittate, the cells open- 

 ing by an oblique pore or short chink. Style not exserted; stigma truncate. 

 Capsule short. 



1. Menziesia ferruginea Smith Ic. PI. 3: pi. 56. 1791. Erect or straggling 

 shrub, 1-2 m. high: leaves oblong or elliptic, acute at both ends, often with 

 strigose-chaffy, ferruginous scales, more or less rusty strigose above, paler 

 beneath, usually mucronate and ciliate with glandular bristles: filaments 

 glabrous or ciliate below: capsule ovate: seeds apiculate or appendaged at 

 each end. (M. urceolaria Salisb.; M. glabella Gray.) — ^Yellowstone Park to 

 Oregon and Alaska. 



4. EALMIA L. American Laurel 



Leaves evergreen and entire. The showy flowers umbellate-clustered, rose- 

 colored, purple, or white. Limb of the corcUa in bud strongly 10-keeled from
