or solitary ; pedicels bracteate and sometimes bi-bracteolate. Flowers 
regular or (in Rhododendron) slightly irregular, hermaphrodite, some- 
times dimorphous. Calyx free or (in Diplycosia) sometimes adnate to 
the ovary, with 5 rarely 4 or 6, teeth or lobes. Corolla hypogynous, 
persistent or deciduous, campanulate cylindric or urceolate, with 4 or 
5 (rarely 6 to 10) imbricate or contorted, rarely valvate teeth or lobes 
(polypetalous in Pyrola). Stamens hypogynous or slightly attached to 
the base of the corolla ; 10, or sometimes 5, 8, or 20 (in Diylycosia 
sometimes epigynous) ; filaments free or united into a tube by their 
bases ; anthers 2-celled, basi- or dorsi-fixed, dehiscing by apical pores 
or slits, the cells often prolonged into apical tubes, sometimes dorsally 
spurred. Disk various, annular or convex, crenate or lobed, sometimes 
absent. Ovary 5-celled (rarely 4- to 16-celled) ; style slender, cylin- 
dric ; stigma capitate or plane, entire or shortly lobed. Ovules 
numerous, rarely few, on placentas in the inner angles of the cells or 
pendulous from the upper corner. Fruit capsular, 5-celled, many- 
seeded, sometimes appearing baccate from the adherence of the enlarged 
succulent calyx. Seeds many, small, angled or compressed, albumi- 
nous ; the testa often loose. — Distrib. About 1,200, in all parts of the
