 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-

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

 anther-cell bearing a defiexed awn ; seeds scobiform. 



3. A. floribiinda 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 colurnella 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. nltida (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 2-toothed near the apex ; capsule ovoid- 

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

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

 and calves. 



3. L. ligustrina (L.) DC. (MALE BERRY.) Minutely pubescent, 0.6-3 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 south w. June, July. 



Var. foliosifl6ra (Michx.) Fernald. Racemes less crowded, often more elon-
