Description

Family Pentaphylacaceae

Shrubs or trees , evergreen . Stipules persistent . Leaves simple , alternate. Flowers axillary , bisexual , actinomorphic , arranged into pseudospikes or pseudoracemes along branchlets below apex. Bracteoles 2, persistent, close to calyx. Sepals 5, persistent, unequal, imbricate. Petals 5, white, imbricate in bud, basally slightly connate . Stamens 5, inflexed in bud, alternate with petals, shorter than petals; anthers small, 2-celled, dehiscing by apical pores . Ovary superior, 5-loculed; ovules 2 per locule, collateral , pendulous from locule apex; style simple, apically 5-lobed. Capsule 5-loculed, loculicidal. Seeds 2 per locule; embryo U-shaped; endosperm very thin.

One species: China, Indonesia (N Sumatra), Malaysia, Vietnam.

This family is sometimes included in the subfamily Ternstroemioideae within the Theaceae.[1]

Genus Eurya

Shrubs , small trees , or rarely large trees, evergreen , dioecious. Current year branchlets terete or 2- or 4-ribbed; winter buds exposed. Leaves distichous; leaf blade margin usually serrulate . Flowers axillary or congested on leafless branchlets, solitary to several in a cluster , small, pedicellate . Bracteoles 2, close to sepals, alternate. Sepals 5, persistent , imbricate, unequal. Petals 5, white or yellowish, basally slightly connate . Male flowers: stamens 5-35, in 1 whorl; filaments linear , glabrous , free or adnate to base of petals; anthers ovate-oblong to oblong , basifixed , 2-loculed, sometimes locellate (constricted at several places along anther length), connective slightly exserted; pistillode conspicuous . Female flowers: stamens usually absent or sometimes present as staminodes; ovary superior, 2-5-loculed with 3-60 ovules per locule, placentation axile ; style 2-5, distinct or variously connate. Fruit baccate , globose , ovoid , or ellipsoid , with 2-60 seeds per locule. Seeds black, globose, shiny, foveolate-pitted; endosperm fleshy ; embryo recurved.

About 130 species: Bhutan, Cambodia, China, NE India, Indonesia, Japan, Korea, Laos, Malaysia, Myanmar, Nepal, Philippines, Sri Lanka, Thailand, Vietnam; Pacific islands; 83 species (63 endemic) in China.

Although some Eurya species are very distinctive, many of them are very similar and difficult to differentiate. It is quite possible that future systematic studies may decrease the number of recognized species in China.[2]
