Description
Family Clethraceae
Trees
or shrubs
, evergreen
or deciduous. Buds, branches, leaf blades
, inflorescences, and flowers with sparse to dense usually stellate
hairs
, often mixed with simple
hairs. Branches sympodial, usually pubescent
at least when young. Stipules absent. Leaves alternate, simple, generally crowded near apex of twigs
; leaf blade usually abaxially ± pubescent and adaxially glabrous
or glabrescent
, margin
serrate or occasionally entire. Inflorescences terminal
, usually a many-flowered slender raceme
, either solitary or umbellate-clustered, sometimes sparsely branched near base
and thus appearing paniculate
, pubescent, bracteate
. Flowers bisexual
, actinomorphic
. Pedicel articulated at base of sepals. Sepals 5, imbricate, persistent
. Petals 5, usually white, free
or coherent at base, oblong
to obovate
, inside often pilose
from base to middle
, apical margin
often fimbriate, apex rounded- to truncate-emarginate. Stamens 10, in 2 whorls, distinct
but generally adnate
to base of petals; anthers
inverted
at anthesis
, ± V-shaped, introrse
, papillose
, opening by short apical pores
. Ovary superior, 3-locular, globose
but apically depressed
at style base, pubescent, with axile placentation
; ovules 20-40 per locule. Style 1, persistent, apex usually 3-cleft or -lobed. Capsule subglobose to globose, pubescent, 3-locular. Seeds many, ovoid-subtrigonous, thin-walled, surface impressed-reticulate.
One genus and ca.

) ; seven species (three endemic) in China.[1]
