The other genera differ from the Iris in having the lower part of the segments of the perianth generally combined into a tube, with the ovary below, looking like a footstalk; the limb being divided into six parts, all so much alike, both in form and position, as to render it difficult to distinguish the calyx from the corolla. There is only one style, with three stigmas, which are always more or less leafy, and the anthers (which are never more than three) are always turned away from the pistil. In Ferraria, the filaments of the stamens grow together, and form a hollow tube, as in the Passion-flower, surrounding the style and stigmas; and in the Saffron Crocus (_C. sativa_), the stigmas (which, when dried, form the saffron) are so heavy, as to hang out on one side of the perianth from between the segments. Most of the genera have solid bulbs or corms at the base of their stems; but some, such as Marica, Sisyrinchium, and Patersonia, have only fibrous roots. The genera Colchicum and Bulbocodium very much resemble the Crocus in the appearance of their flowers; but they are distinguished by having three styles and a superior ovary, and they are included in the order Melanthaceæ. ORDER CLXXXVIII.—HÆMODORACEÆ. The principal genera are Wachendorfia, Hæmadorum, and Anigozanthos, which differ from the preceding genus principally in having six stamens, the anthers of which are turned towards the stigma. Most of the genera have only fibrous roots, but Wachendorfia has a rhizoma, producing buds in the scales. The plants are natives of the Cape of Good Hope and New Holland, and the roots of some of the species yield a brilliant scarlet dye. ORDER CLXXXIX.—HYPOXIDEÆ. Bulbous-rooted plants, with long narrow leaves covered with soft downy hairs, and rather small yellow flowers, which are frequently fragrant. ORDER CXC.—AMARYLLIDACEÆ.
