Arctostaphylos.] +=-XLY, ERICACER, 281 
A high alpine or Arctic plant, common in the mountains of northern 
Europe, Asia, and America, and at high altitudes in the central chains 
of the two former continents. In Britain, only in the central and 
northern mountains of Scotland, extending to Shetland. Fl. spring. 
IV. ANDROMEDA. ANDROMZEDA. 
Small shrubs or herb-like undershrubs, chiefly growing in peat-bogs, 
with the flowers of an Arbutus, 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 modern botanists to the single British 
species, but usually extended so as to comprise several other North 
American, as well as Asiatic and Huropean species. 
1. A. polifolia, Linn. (fig. 633). Marsh A.—A low, branching, 
herb-like shrub, seldom above 6 inches high, and quite glabrous. 
Leaves alternate, 4 to 1 inch long, oblong-lanceolate, evergreen, with 
their edges rolled back, and very glaucous underneath. Flowers on 
rather long pedicels, in short, terminal 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, southern and central Scotland 
and Ireland, but absent from the Scotch Highlands, where the plants of 
similar Continental distribution are usually found. FV. all summer. 
V. LOISELEURIA. LOISELEURIA. 
A low, trailing shrub, with small opposite leaves. Sepals 5. Corolla 
campanulate, 5-lobed. Capsule free, with 2 or 3 cells, opening in as 
many valves by the splitting of the partitions, and containing several 
seeds, 
The single species of which this genus consists was included by 
Linnzeus among his Azaleas, and some botanists retain that name for 
it, proposing to give that of Anthodendron to the showy shrubs so well 
known as Azaleas in our American gardens, but such a change would 
entail great useless confusion in synonymy, and the name of Loiseleuria 
is now generally adopted, at least by Continental botanists. [Moreover 
the name Azalea was applied by Linnzus primarily to the Indian plant 
of that name, and has been retained by almost all succeeding botanists 
for it and its allies, which only differ from many Rhododendrons in 
their deciduous leaves. Loiseleuria differs from all these in its opposite 
leaves, and in its anthers opening by lateral slits. ] 
1. L. procumbens, Desv. (fig. 634). Lotseleurta.— Leaves numerous, 
evergreen, only 2 or 3 lines long, ovate or oblong, shining on their 
upper side, with the edges rolled back. Flowers small and rose- 
coloured, in short terminal clusters. Valves of the capsule usually 
shortly split at the top. Azalea procumbens, Linn.
