The same is the case with the stamens formed each of a short ^ free filament, inflexed in the bud, and a short bilocular introrse anther, dehiscing by two longitudinal clefts, afterwards versatile. They are indefinite in number, sometimes few, and appear, at adult age, disposed in a single series, though unequal.* The gynse- cium is composed of an inferior ovary, im- bedded at the bottom of a receptaeular cavity united with it to a variable extent, above ^ almost flat or slightly convex. It may have five oppositipetalous cells, or less," or many more,^ and it is surmounted by a style, the stigmatiferous extremity of which is trun- cate, or capitate, or peltate. In the internal angle of each cell are found ovules ordinarily Fig. 290. Fioriferous branch (j). very numerous, more rarely indefinite in number. The mode of insertion is very variable. Sometimes they are arranged in two series, on a slight placentary projection, and sometimes in a circle on the margin of a peltate placenta, itself attached to the internal angle by a short horizontal or oblique foot.® They are anatropous, rectilinear, or curved.^ The fruit (fig. 293), the base of which is imbedded in the receptaeular capsule, is a de- pressed, loculicidal capsule, the seeds of which, linear, cuneiform or angular, not unfrequently winged or ciliate, enclose a straight fleshy embryo, with elongate cotyledons. Lejptospermum consists of small. ' The gynaecium is not unfreqiiently aborted. ^ A character -which soon disappeaiB. ' Its base is often swollen and articulate as it were to the margin of the disk.
