256 ERICACEAE. (HEATH FAMILY.) 



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

 reason), slightly glandular, many-flowered ; pod depressed, nenrly 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. glaiica, Ait. (PALE LAUKEL.) Branchlets 2-cdaed ; leaves opj>o- 

 site, Hi-nrly .sr.ss/A', oblong, white-glaucous underneath, witli n'mhttc. man/his ; corymbs 

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

 MAKINIFOLIA has linear and strongly revolute leaves. Cold peal-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 sumon : calyx leafy, 

 larger than the }jod, nearly equalling the corolla, at length deciduous ; leaves (alter- 

 nate and opposite} and branches bristly-hairy . 



4. K. tlirsuta, 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. MENZIKSIA. 



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

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

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

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

 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 A. Menzies, who in Vancouver's 

 voyage brought the species from the Northwest Coast.) 



1. M. feiTUgiiiea, Smith: var. globularis. 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. AZALEA, L. FALSE HONEYSUCKLE. AZALEA. 



Calyx 5-partcd, often minute. Corolla funnel-form, 5-lobcd, slightly irregu- 

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

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

 pointless. Pod 5-ccllcd, 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 umbelled clusters from large scaly-imbri- 

 cated terminal buds. (Name from ofoXcoff, arid, most inappropriate as ap- 

 plied to our species, which grow in swamps.) 



* Flowers appearing after the leaves. 



1. A. firborescens, Pursh. (SMOOTH AZALEA.) Branchlets smooth; 

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

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