MesembryantliemacCEB {Fig-Marigold Family) consists ofsucculent plants, with showy flowers opening only under bright sun-shine, containing an indefinite number of petals and stamens, and amany-celled and many-seeded capsule: otherwise much as in Caryo-phyllaceae. — Ex. Mesembryanthemum (Fig-Marigold, Ice-plant) ;chiefly natives of the Cape of Good Hope, flourishing in the mostarid situations. 771. Ord. Malvaceae {Mallow Family). Herbs, shrubs, or rarelytrees. Leaves alternate, palmately veined, with stipules. Flowersregular, often with an involucel, forming a double calyx. Calyxmostly of five sepals, more or less united at the base, valvate in FIG. 728. Flower of the Purslane; the calyx cut away at the point where it adheres to theovary, and laid open. 729. A capsule (pyxis) of the same, transversely dehiscent. 730.
