256 EKicACE^. (heath family.) 



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

 season), slightly glandular, many-flowered; pod depressed, neai-ly smooth. — 

 Hill-sides, common. May -July. — Shrub 2° -3° high, upright: the flowers 

 more crimson, and two thirds smaller than in the last. 



3. K. glanca, Ait. (Pale Laurel.) Branchlets 2-edged; leaves oppo- 

 site, nearly sessile, oblong, white-glaucous underneath, with revolute margins ; corymbs 

 terminal, few-flowered, smooth ; bracts large ; pod ovoid, smooth. — Var. Kos- 

 makinip6lia has linear and strongly revolute leaves. — Cold peat-bogs and 

 mountains, from Pennsylvania northward. July. — Straggling, about 1° high. 

 Plowers ^' broad, lilac-purple. 



5 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. hirsnta, 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. 



15. fflEl^ZIESIA, Smith. Menziesia. 



Calyx very small and flattish, 4-toothed or 4-lobed. Corolla cylindi'aceon.s- 

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

 anther-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 slu'ub, with 

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

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

 small, developed with the leaves, in terminal clusters from scaly buds, gi'eonish- 

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

 voyage brought the species from the Northwest Coast. ) 



1. M. ferriig^iiiea, Smith: var. g'lolbularis. Corolla rather shorter 

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

 Pennsylvania to Virginia, &c. June. — Leaves tipped with a gland. 



16. AZAliEA, L. False Honeysuckle. Azalea. 



Calyx 5-parted, often minute. Corolla funnel-form, 5-lobed, slightly irregu- 

 lar ; the lobes spreading. Stamens 5, with long exserted filaments, usually 

 declined, as well as the similar style : anthers short, opening by terminal pores, 

 pointless. Pod 5-celled, 5-valved, many-seeded. Seeds scale-like. — Upright 

 shrubs, with alternate and obovate or oblong deciduous leaves, which are entire, 

 ciliate, and mucronate with a glandular point. Flowers large and showy, often 

 glandular and glutinous outside, in umbellcd clusters from large scaly-imbri- 

 cated terminal buds. (Name from d^aXeos, arid, — most inappropriate as ap- 

 plied to our species, which grow in swamps.) 



* Fhwers appearing after the leaves. 



1. A. arborescens, Pursh. (Smooth Azalea.) Branchlets smooth; 

 leaves obovate, obtuse, very smooth both sides, shining above, glaucous beneath, the
