Small trees, or shrubs, with terete branchlets and fibrous roots. 
petiolate, membranaceous or coriaceous, deciduous or persistent. 
Leaves alternate, entire or serrate, 
Flowers in axillary and terminal 
umbellate fascicles or panicled racemes. Pedicels slender, produced from the axils of ovate acute bracts, 
and bibracteolate at the base. Calyx free, persistent, five-toothed or parted nearly to the bottom, 
the divisions ovate-acute, sometimes herbaceous. Corolla gamopetalous, deciduous, globose or ovate- 
urceolate or nearly cylindrical, five-toothed or five-lobed, glabrous, pubescent, or glandular, white or 
rose-colored. Stamens eight or ten, included; filaments flat, broad or narrow, usually slightly adnate 
to the base of the corolla, often bearded, narrowed or dilated at the base, sometimes geniculate, and 
often furnished below the apex with two horn-like appendages; anthers short, oblong or lanceolate, 
attached on the back, two-celled, introrse, the cells opening below the apex by two oblong pores, 
furnished on the back with one ascending deflexed awn or with two ascending awn-like appendages, : 
or muticous; pollen grain compound. Disk ten-lobed. Ovary five-celled, depressed in the centre ; 
style columnar, tipped with a simple truncate stigma; ovules numerous in each cell, attached to a 
placenta borne next the summit or near the middle of the axis, anatropous; raphe ventral; micropyle 
superior. Fruit dry, capsular, ovoid, globose or subglobose, many-seeded, loculicidally five-valved, the 
valves septiferous and separating from the placentiferous axis, sometimes five-ribbed by the thickening 
of the valves at the dorsal sutures, the ribs more or less separable in dehiscence. Seeds pendulous or 
spreading in all directions, oval, sometimes angled or scobiform ; testa crustaceous, smooth and shining, 
or loose, thin, reticulate, and sometimes produced at both ends beyond the nucleus. Embryo axile in 
fleshy albumen, cylindrical, elongated ; cotyledons much shorter than the terete radicle, turned towards 
the hilum.’ 
About twenty species of Andromeda, as the genus is here regarded, are distinguished ; they are 
chiefly confined to the temperate and southern parts of eastern North America, to the mountains of
