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 ROSEMARY.) Similar in 

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

 lets and bud-scales glaucous; flowers 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. PORTtJNA (Nutt.) Gray. Corolla ovoid-urceolate ; each 

 anther-cell bearing a deflexed awn ; seeds scobiform. 



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

 young branchlets, etc., strigose-hairy ; leaves lanceolate- branch x %. 

 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 Alleghenies from Va. to Ga. 

 May. 



18. LY6NIA 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 

 Alleghenies.) 



* Leaves coriaceous and evergreen. 



1. L. nitida (Bartr.) Fernald. (FETTER BUSH.) Glabrous shrub, 0.5-1.5 m. 

 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-BUSH.) Mostly glabrous, 5-10 dm. 

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

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

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



Low grounds, K. I. to Fla., Tenn., and Ark. Foliage said to poison lambs 

 and calves. 



3. L. ligustrina (L.) DC. (MALE BERRY.) Minutely pubescent, 0.5-3 m. 

 high ; 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. ; Xolisma Britton.) Moist thickets, centr. 

 Me. to centr. N. Y., and southw. June, July. 



Var. foliosifl&ra (Michx.) Fernald. Racemes less crowded, often more elon- 

 gate, conspicuously leafy-bracted. (Xolisma foliosifl.ora Small.) Common 

 southw. , local and less characteristic northw.
