The plants belonging to this order are easily known by the stamens, or rather anthers, for they have scarcely any filaments, being affixed to the corolla in the centre of the lobes, instead of being alternate to them, and by the capsule, though five or ten ribbed, being only one-celled, with a central placenta, to which the seeds are attached. The calyx remains on the ripe fruit. In the genus Primula (the Primrose), the calyx is tubular, and strongly marked with five distinct angles, which end in as many teeth; and the corolla is salver-shaped, with a contraction in the tube, at the insertion of the stamens, the five segments of the limb being wedge-shaped and notched. The style is slender, and the stigma capitate. The capsule opens naturally by ten teeth, which curl back. The Cyclamen, or Sow-bread, one of the genera belonging to this order, has the lobes of the corolla bent back; and when the flower falls, the peduncle coils up in a most curious manner, so as to bury the seed-vessel in the earth. These plants have tuberous roots, which are so acrid as only to be eaten by the wild-boars. The seed-vessel of the Pimpernel (_Anagallis_) resembles a round case with a lid, which may be taken off, when it displays a great number of seeds, so closely packed, that no room is lost. The principal other genera are the American Cowslip (_Dodecatheon_), Bear’s-ear Sanicle (_Cortusa_), _Soldanella_, the Water Violet (_Hootonia_), and Loosestrife (_Lysimachia_). ORDER CXLIX.—GLOBULARIÆ. Pretty alpine plants, with blue flowers. ORDER CL.—PLUMBAGINEÆ. This order probably belongs to Monochlamydeæ. The principal genera are Sea Lavender (_Statice_), remarkable for the coloured footstalks of the flowers; Thrift (_Armeria_); and Leadwort (_Plumbago_). The corolla in these plants is either monopetalous, with the stamens free from the corolla and growing from beneath the pistil, or with five petals, to which the stamens are attached. There are five styles and five stigmas, but only a one-celled and one-seeded ovary. The fruit is thin and dry. The pedicels of all the species of the Sea Lavender, particularly of _Statice arborea_, are often mistaken for the flowers. CHAPTER II. PHANEROGAMOUS PLANTS—DICOTYLEDONEÆ.—II. MONACHLAMYDEÆ. In all the plants contained in this division, the stamens and pistils have either no floral covering, or only one; and as, when this is the case, the covering is called the calyx, the plants in this division are said to have no corolla. Some botanists think that the calyx and corolla have become intermixed, so as to form only one covering, which they call the perianth; a word applied to the calyx and corolla together. ORDER CLI.—PLANTAGINEÆ.
