Beguea apetala Capuron.

Typus: Beguea apetala Capuron. Dioecious small to large trees with simple or rarely stellate-fasciculate indument. Leaves alternate, trifoliolate or paripinnately compound with 4-30 alternate to subopposite, entire leaflets, the rachis usually extending slightly beyond the terminal leaflet giving the impression of an aborted leaflet; pseudostipules absent. Inflorescences axillary, sometimes borne on stems below the leaves (ramiflorous), long racemose. Flowers actinomorphic; calyx united basally, (5-)6-7(-8)-lobed; petals absent; disc cushion-shaped, the margin sinuate; stamens 6-8(-10), filaments long, slender, anthers ovate to oblong, laterally dehiscent; staminodia in female flowers resembling short stamens; ovary 3-locular, style longer than the ovary, dividing apically into 3 distinct stigmas, ovule 1 per locule; pistillode in male flowers minute. Fruit indehiscent, globose to obovoid, 1-seeded, dry to somewhat fleshy or woody, crowned by the apiculate remnant of the style; seed surrounded by a translucent, fleshy arillode, the hilar scar basal, the cotyledons highly ruminate. Notes. – A genus of ten species, occurring in humid and subhumid forest, rarely in dry forest. The genus name honors the French botanist Louis H. Bégué, who founded the Service Forestier collection series in Madagascar.模式种：无瓣贝盖木（Beguea apetala Capuron）。 雌雄异株小至大乔木，被单毛或稀具星状簇生毛被。叶互生，为三出复叶或偶数羽状复叶，具4-30片互生至近对生的全缘小叶；叶轴通常略延伸于顶生小叶之外，使人误以为存在一枚退化小叶；无假托叶。花序腋生，有时生于叶下方的老茎上（老茎生花），为长总状花序。花辐射对称；花萼基部合生，(5-)6-7(-8)裂；无花瓣；花盘垫状，边缘波状；雄蕊6-8(-10)，花丝细长，花药卵形至长圆形，侧缝开裂；雌花具退化雄蕊，形似短雄蕊；子房3室，花柱长于子房，顶端分裂为3个独立的柱头，每室具1枚胚珠；雄花具细小的退化雌蕊。果实不开裂，球形至倒卵形，具1粒种子，干燥至稍肉质或木质，顶端具宿存的尖柱状花柱残迹；种子被半透明肉质假种皮包裹，种脐位于基部，子叶高度嚼烂状。 注：本属共10种，分布于湿润及亚湿润森林，极少见于干旱森林。该属名以法国植物学家路易·H·贝盖（Louis H. Bégué）命名，他创立了马达加斯加的Service Forestier馆藏系列。
