those of the last species ; the leaves rather narrower, and very different in 

 consistence, being thin, strongly veined, toothed at the top, and withering 

 away at the end of the season. Young shoots surrounded by the scales of 

 the leaf-btids, which remain long persistent. Flowers small, usually 2 or 3 

 together, on short, drooping pedicels. 



A liigh alpine or Arctic plant, common in the mountains of northern 

 Europe, Asia, and America, and at high altitudes in the more central 

 chains of the two former continents. In Britain, only in the northern 

 Highlands of Scotland, including Ben Nevis. Fl. spring. 



IV. ANDROMEDA. ANDKOMEDA. 



Small shrubs or herb-hke undershrubs, chiefly growing in peat-bogs, with 

 the flowers of an j4/'Jm<(w, but a dry capsular fruit opening in as many entire 

 valves as it has cells, by slits placed in the middle of the cells, not by the 

 splitting of the partitions as in Menziesia, each cell containing several 

 seeds. 



A small genus, limited by some modem botanists to the single British 

 species, but usually extended so as to comprise several other North Ame- 

 rican, as well as Asiatic and European species. 



1. MCarsh Andromeda. Andromeda polifolia, Linn. 



(Eng. Bot. t. 713.) 



A low, branching, herb-hke shrub, seldom above 6 inches high, and 

 quite glabrous. Leaves alternate, 1 to 1 inch long, oblong-lanceolate, ever- 

 green, with their edges rolled back, and very glaucous underneath. Flowers 

 on rather long pedicels, in short, termmal racemes or clusters ; the calyx 

 small, deeply 5-lobed ; the corolla pale pink, ovoid, enclosing the 10 stamens. 



In peat-bogs in northern Europe, Asia, and America, to the Arctic 

 regions, and in the great mountain-chains of central Europe. In Britain, 

 confined to central and northern England and southern Scotland, but 

 absent from the Scotch Higlilands, where the plants of similar Continental 

 distribution are usually found. Fl. all summer. 



V. LOZSEIaEXTRIA. LOISELEUEIA. 



A low, trailing shrub, with small, opposite leaves. Sepals 5. Corolla cam- 

 panulate, 5-lobed. Capsule free, with 2 or 3 cells, opening in as many 

 valves by the sphtting of the partitions, and containing several seeds. 



The single species of which this genus consists, was included by Lin- 

 naeus among liis Azaleas, and some botanists retain that name for it, 

 proposing to give that of Anlhodendron to the showy shrubs so well 

 knowm as Azaleas in our American gardens, but such a change would 

 entad great useless confusion in synonymy, and the name of Loiseleuria 

 is now generally adopted, at least by Continental botanists. 



1. Trailing Xioiseleuria. Zioiseleuria procumbeus, Desv. 



{Azalea, Eng. Bot. t. 865.) 

 Leaves numerous, evergreen, only 2 or 3 lines long, ovate or oblong, 

 shining on their upper side, with the edges rolled back. Flowers small,
