. A text-book of botany for secondary schools. Botany. DICOTYLEDONS: ARCHICHLAMYDE^ 296 tiums, fuchsias, etc.; and some very useful plants also belong to scattered families. These latter may be grouped as follows: (1) Fibers.—The fiber plants are numerous, but there are three very conspicuous ones among the Archichlamydeae. Cotton.—The cotton plant is by far the most important fiber plant grown, being cultivated over a greater area and used for a larger nunaber of purposes than any other fiber plant (Fig. 285). The cultivated va- rieties have originated from several tropical spe- cies, but in the United States the Sea Island cotton and the upland cotton are grown almost exclusively. The genus {Gossypium) belongs to the Mallow Family {Mal- vacece), to which the hol- lyhock and the hibiscus also belong, the most con- spicuous peculiarity of the flower being the ap- parent coalescence of the numerous stamens into a central column (Fig. 214). The capsule (boll) of the cot- ton plant contains numerous seeds, which are covered with long hairs (lint) that are the cotton fibers (Fig. 285, C). At maturity the bolls burst, and the lint protrudes in a fluffy, cottony mass (Fig. 285, B). The cotton-gin was in- vented to separate the lint from the seeds, and the revolu- tion it brought about in the cotton industry is well known. The Sea Island cotton, with its long and silky fibers, is 30. Fig. 285.—The cotton plant: A, flowering branch ; B, fruit (boll) bursting; C, seed with fibers (lint).—After Wossidlo..
