either flat or revolute, glabrous, generally whitened beneath with a varnish-like 



coat, later often green; bud-scales scarcely glaucous; pedicels in terminal umbels, 

 filiform, straightish, 2-4 times exceeding the nodding flower 

 and erect fruit; corolla pink or white; calyx with pale or 

 usually reddish slightly ascending lobes; capsule brown or 

 reddish, obovoid or subglobose, as high as broad. — Arctic 

 regions, extending very locally s. to the Adirondack Mts., 

 N. Y.(?), L. Huron, etc. May-July. (Eurasia.) Fig. 844. 



2. A. glaucophylla Link. (Bog Eosemaky.) Similar in 

 habit ; leaves white beneath with close fine pubescence ; branch- 

 lets and bud-scales glaucous; fiowers on 

 thickish curved pedicels rarely twice their 

 length; calyx-lobes whitish, usually spread- 

 ing; capsule depressed, turban-shaped, glau- 

 cous. {A. Polifolia mostly of Am. auth,, 

 not L.) — Bogs and wet shores. Lab. to 



Man., s. to N. J., Pa., and Minn. May-July ; rarely Sept., 



Oct. Fig. 845. 



§ 2. PORTtlNA (Nutt.) Gray. Corolla ovoid-urceolate ; each 

 anther-cell bearing a deflexed awn ; seeds scobiform. 



3. A. floribunda Pursh. Very leafy, 5-15 dm. high ; 

 young branchlets, etc., strigose-hairy ; leaves lanceolate- 

 oblong, acute or acuminate, ciliate-serrulate, glandular-dotted 

 beneath, 4-6 cm. long ; racemes crowded in short terminal panicles, densely 

 flowered. {Pieris B. & H.) — Moist hillsides, in the AUeghenies from Va. to Ga. 

 May. 



18. LYOnIA Nutt. 



Similar to Andromeda. Filaments hairy and often toothed or appendaged ; 

 anthers oblong, unappendaged. Capsule 5-angled, the dorsal sutures with a 

 thickened ridge, which usually divides in dehiscence of the capsule ; the placentae 

 borne both upon the columella and the walls of the cells. Seeds scobiform, with 

 a loose thin testa. — Shrubs with fascicled, racemose, or panicled white flowers. 

 (Named for John Lyon, early American botanist and explorer of the southern 

 AUeghenies.) 



* Leaves coriaceous and evergreen. 



1. L. nitida (Bartr.) Fernald. (Fetter Bush.) Glabrous shrub, O.^l.bm. 

 high ; branches sharply triangular ; leaves glossy, oblong-ovate to lanceolate, 

 acuminate, entire, with a conspicuous nerve next the revolute margin; flowers 

 in axillary umbels; filaments appendaged at summit; capsule subglobose. 

 (Andromeda Bartr. ; Pieris B. & H.) — Low woods and barrens, Va. to Fla. 

 and La. May. 



* * Leaves thinnish and deciduous. 



2. L. mariana (L.) D. Don. (Stagger-busii.) Mostly glabrous, 5-10 dm. 

 high ; leaves oblong or oval, 3.5-8 cm. long ; fascicles of nodding floicers race- 

 mose on leafless shoots; filaments 2-toothed near the apex; capsule ovoid- 

 pyramidal, truncate at the contracted apex. {Andromeda L. ; Pieris B. & H.) 

 — Low grounds, R. L to Fla., Tenn., and Ark. — Foliage said to poison lambs 



3. L. ligustrina (L.) DC. (Male Berry.) Minutely pubescent, 0.5-3 m. 

 hi?h ; leaves obovate to lanceolate-oblong, 2.5-8.5 cm. long, serrulate or entire; 

 racemes crowded in chiefly naked panicles ; filaments flat, not appendaged; cap- 

 sule globular. (Andromeda Muhl. ; J^olisma Britton.) —Moist thickets, centr. 

 Me. to centr. N. Y., and south w. June, July, 



Var. foliosiflbra (Michx.) Fernald. Kaceraes less crowded, often mnre elon- 

 gate, conspicuously leafy-bracted. (^Xolisma foliosiflora Small.) — Common
