256 ERICACEAE. (HEATH FAMILY.) 



t 



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

 season), slightly glandular, many-flowered; pod depressed, nearly 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. glauca, Ait. (PALE LAUREL.) BrancMets 2-edaed ; leaves oppo- 

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

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

 MARINIF6LIA has linear and strongly revolute leaves. Cold peat-bogs and 

 mountains, from Pennsylvania northward. July. 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. liirsiita, 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. 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 : 

 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 IOAV shrub, with 

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

 those of A/alea) 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 A. Mcnzies, who in Vancouver's 

 voyage brought the species from the Northwest Coast.) 



. 1. M. ferrilginea, Smith: var. glob ilia 1'iS. Corolla rather shorter 

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

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



16. AZALEA, L. FALSE HONEYSUCKLE. AZALEA. 



Calyx 5-parted, often minute. Corolla funnel-form, 5-lobcd, 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-vaived, 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 umbelled clusters from large scaly-imbri- 

 cated terminal buds. (Name from aaXeos, and, most inappropriate as ap- 

 plied to our species, which grow in swamps.) 



* Flowers appearing afler the leaves. 



1. A. arfoorescens, Pursh. (SMOOTH AZALEA.) Branchkts smooth; 

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

 margins bristly -ciliate ; calyx-lobes long and conspicuous ; corolla slightly clammy ;
