Shrubs, with terete or nearly terete branches. Leaves alternate, persistent; blades broad 
or narrow, leathery, entire or nearly so, short-petioled. Flowers in raceme-like panicles 
which arise from the axils of the leaves near the ends of the branches, disposed thus in terminal 
panicles. Calyx persistent; lobes 5, mostly of a lanceolate type, appressed to the corolla, 
leathery. Corolla white or nearly so, pyramidal, usually narrow; tube prominently fluted or 
angled, the ridges protruding between the calyx-lobes and often saccate at the base; lobes 
very short, slightly spreading. Stamens 10, included; filaments slender, straight or nearly so, 
unappendaged; anthers short, oval or ovoid, each sac with a slender dorsal appendage. Ovary 
5-celled, lobed, globular or depressed; style columnar; stigma minute. Capsule globular, the 
sutures not thickened. 
Type species, Andromeda formosa Wall.
