298 ERICACEAE. (HEATH FAMILY.) 



naked buds, and showy flowers. (Dedicated to Peter Kalm, a- pupil. of -Linnaeus 

 who travelled in this country about the middle of the last century, afterwards 

 Professor at Abo.) 



§ 1. Flowers in simple or clustered naked umbel-like corymbs: pedicels from the axils 

 of small and firm fuliaceous persistent bracts : calyx smaller than the pod, per- 

 sistent : leaves glabrous. 

 1. K. latiiblia, L. (Calico-bush. Mountain Laurel. Spoon- 

 wood.) Leaves mostly alternate, bright green both sides, ovate-lanceolate or ellipti' 

 cal, tapering to each end, petioled ; corymbs terminal, many-flowered, clammy, 

 pubescent; pod depressed, glandular. — Eocky hills and damp soil, rather 

 common from Maine to Ohio and Kentucky, as a shrub 4° - 8° high ; but in 

 the mountains from Penn. southward forming dense thickets, and often tree- 

 like (10° -20° high). May, June. — Flowers profuse, large and very showy, 

 varying from deep rose-color to nearly white, clammy. 



2. K. angUStifblia, L. (Sheep Laurel. Lambkill.) Leaves com- 

 monly opposite or in threes, pale or whitish underneath, light green above, narrowly 

 oblong, obtuse, petioled; corymbs lateral (appearing later than the shoots of the 

 season), slightly glandular, many-flowered; pod depressed, nearly smooth; 

 pedicels recurved in fruit. — Hillsides: common. May, June. — Shrub 2° -3° 

 high : the flowers more crimson and two thirds smaller than in the last. 



3. K. glauca, Ait. (Pale Laurel.) Branchlets 2-edged : leaves opposite, 

 nearly sessile, oblong, white-glaucous beneath, with recolute margins ; corymbs termi- 

 nal, few-flowered, smooth ; bracts large ; pod ovoid, smooth. — Var. rosmari- 

 nif6lia has linear and strongly revolute leaves. — Cold peat-bogs and moun- 

 tains, from Pennsylvania northward. May, June. — Straggling, about 1° high. 

 Flowers %' broad, lilac-purple. 



§ 2. Flowers scattered, solitary in the axils of the leaves of the season: calyx leafy, 

 larger than the pod, nearly equalling the corolla, at length deciduous : leaves (alter- 

 nate and opposite) and branches bristly-hairy. 



4. K. hirsilta, Walt. Branches terete ; leaves oblong or lanceolate (4'' 

 long), becoming glabrous. — Sandy pine-barren swamps, E. Virginia and south- 

 ward. May -Sept. — Shrub 1° high. Corolla rose-color. 



16. MENZIESIA, Smith. Menziesia. 



Calyx very small and flattish, 4-toothed or 4-lobed. Corolla cylindraceous- 

 urn-shaped and soon bell-shaped, obtusely 4-lobed. Stamens 8, included : an- 

 ther-cells opening at the top by an oblique pore. Pod ovoid, woody, 4-celled, 

 4-valved, many-seeded. Seeds narrow, with a loose coat. — A low shrub ; 

 the straggling branches and the oblong-obovate alternate deciduous leaves (like 

 those of Azalea) hairy and ciliate with rusty rather chaff-like bristles. Flowers 

 small, developed with the leaves, in terminal clusters from scaly buds, greenish- 

 white and purplish, nodding. (Named for Archibald Menzies, who in Vancouver's 

 voyage brought the species, from the Northwest Coast.) 



1. M. ferruginea, Smith, var. globularis. Corolla rather shorter 

 and broader than in the Oregon plant. — Alleghany Mountains, S. Pennsyl- 

 vania to Virginia, &c. (Also beyond Lake Superior. ) June.
