. The natural history of plants. Botany. NATUBAL HISTORY OF PLANTS. Stackhousia monogyna. II? STACKHOTJSIA SEKIES. StacJchousia^ (fig. 8-11), wMch has been made a distinct family, has regular and hermaphrodite flowers. The receptacle has the form of a hemispheric cup, the cavity of which is covered with a glandular disk. Outside the more â or less salient or often but slightly developed edges of this disk, the lips of the receptacle give insertion to the perianth and to a perigynous androecium, viz., to five imbricated sepals and five petals alternating with them, much longer exserted, free and remaining so in their lower and upper parts, whilst for a variable extent of the intermediate part they approach and unite by tlieir margins in an elongated tube resembling that of a gamopetalous corolla. The limb is imbricated in pre- floration. The stamens are the same in number as the petals, alternating with them, each formed of a filament free or connate with the corolla and an anther bilocular, introrse, de- hiscing by two longitudinal clefts.^ Generally two of these Stamens, the lateral, are much shorter than the three others. The gynsecium is free to the bottom of the receptacular cup; it is formed of an ovary, often with three, more rarely with two, four or five cells, surmounted by a style divided more or less deeply into stigmatiferous slips equal in number to the ovarian cells. The latter present, near the base of their internal angle, an ascending, anatropous ovule with mycropyle primarily directed downwards and outwards, later turned a little laterally. The fruit is dry, often formed of two or three achenes^ which finally separate from the central column, itself divided into as many fine threads as there are carpels. They. Pig. 8.
