r is apparently below the flower (inferior), and lacking the inner circle of stamens, is the iris family (_Iridaceae_), represented by the wild blue-flag (_Iris versicolor_) (Fig. 84, _A_, _E_), as well as by numerous cultivated species. In iris the carpels are free above and colored like the petals (_B_), with the stigma on the under side. Of garden flowers the gladiolus and crocus are the most familiar examples, besides the various species of iris; and of wild flowers the little "blue-eyed grass" (_Sisyrinchium_). [Illustration: FIG. 85.--_Enantioblastae_. _A_, inflorescence of the common spiderwort (_Tradescantia_), x 1/2 (_Commelyneae_). _B_, a single stamen, showing the hairs attached to the filament, x 2. _C_, the pistil, x 2.] The blue pickerel-weed (_Pontederia_) is the type of a family of which there are few common representatives (Fig. 84, _I_, _K_). The last family of the order is the _Bromeliaceae_, all inhabitants of the warmer parts of the globe, but represented in the southern states by several forms, the commonest of which is the so-called "gray moss" (_Tillandsia_) (Fig. 84, _F_, _H_). Of cultivated plants the pineapple, whose fruit consists of a fleshy mass made up of the crowded fruits and the fleshy flower stalks, is the best known. ORDER II.--_Enantioblastae_. The second order of the monocotyledons, _Enantioblastae_, includes very few common plants. The most familiar examples are the various species of _Tradescantia_ (Fig. 88), some of which are native, others exotic. Of the cultivated forms the commonest is one sometimes called "wandering-jew," a trailing plant with zigzag stems, and oval, pointed leaves forming a sheath about each joint. Another common one is the spiderwort already referred to. In this the leaves are long and pointed, but also sheathing at the base. When the flowers are showy, as in these, the sepals and petals are different, the former being green. The flowers usually open but once, and the petals shrivel up as the flower fades. There are four families of the order, the spiderwort belonging to the highest one, _Commelyneae_. ORDER III.--_Spadiciflorae_. The third order of the monocotyledons, _Spadiciflorae_, is a very large one, and includes the largest and the smallest plants of the whole sub-class. In all of them the flowers are small and often very inconspicuous; usually, though not always, the male and female flowers are separate, and often on different pl
