Description
|
Monoecious or dioecious shrubs; branching opposite or alternate. Leaves borne on short shoots, opposite, simple, succulent, linear, with pointed apices and drying with umbonate or appendaged bases; stipules minute, caducous. Inf lores- cences axillary or terminal, in monoecious species the flowers solitary or in clus- -ters on short, leafy axes, in dioecious species congested in short catkins. Male flowers subtended by a single bract and by a pair of tepallike bracteoles (spathella), the stamens 4, alternating with minute staminodes or appendages, the anthers exserted, dorsifixed, versatile, introse, dehiscing longitudinally, 2-locu- lar; female flowers free or fused into a syncarp, 2-carpellate but 4-locular by a false septum, the ovule 1 in each locule, bitegmic, crassinucellate, erect, basal, epitropous, anatropous, the raphe facing the carpel axis, the style wanting or short, the stigmas 2, fimbriate, persistent. Fruits syncarps or drupes, the outer tissues fleshy or leathery, the endocarp woody, each pistil with 1-4 seeds; seeds oblong, nearly straight, the embryo nearly straight, the endosperm wanting.

Note
|
Although intensively investigated by several workers, e.g., McLaughlin, 1959; van Royen, 1956; Uphof, 1930; and van Heel, 1958, there is still dis- agreement on several important features of these plants, e.g., whether the ovary is superior or inferior and the nature of the perianth and fruit. In the past it has been placed in alliance with a considerable variety of families, but the practice in recent years of placing it in conjunction with the Centrospermae has been dis- credited (Goldblatt, 1976).
