. The natural history of plants. Botany. BUB I AC EM. 267 'Anthoapermum Fig. 237. Male flower (f). â wHch the gyneecium is well developed, the receptacle is sacciform, most frequently obovoid, the cavity lodging the bilocular ovary, sur- mounted by an epigynous disk of little thickness with two very long slender branches, and a style everywhere bristling with papillae. In the male flower the receptacle becomes very small; the ovary dis- appears, and the stylary branches alone, sometimes much reduced in size, may irepresent the gynsecium, Th© calyx in- serted at the mouth of the receptacle is often very short, nearly entire or with persistent teeth of variable size. One or two of ±hem may even become foliaceous. The corolla varies in form in the flowers of the two sexes. In the males it is well developed, bell- or funnel-shaped, glabrous or hairy at ,the throat, with 3-5 vaivate lobes. In the females it^generally becomes small, narrow, tubular with 2-5 erect teeth or lobes, often applied to the styles. The stamens, wanting or remaining rudimentary in the female flowers, number 3-5 in the males, inserted on the tube of the corolla, formed of a very slender and mobile filament, often incurved by the weight of the elongate, exserted, introrse, bilocular, dorsifixed anther dehiscing by two longi- tudinal clefts. In each ovarian cell, quite at the base of the internal a,ngle, is inserted an ascending, anatropous ovule, with micropyle exterior and inferior. The fruit, didymous, compressed perpendicular to the partition, separates into two cocci, indehiscent or dehiscing along the face, and enclosing each a seed with thin coat, covering a fleshy or hard albumen, the axis of which is occupied by an elongate embryo, with foliaceous cotyledons and inferior cylindrical radicle. The Anthpsperms, of which more than a score of species * have been described, natives of southern, eastern and western tropical Africa and Madagascar, are shrubs of small figure, erec
