OP THE FLOWER. Sect. I. Its Organs, or Component Parts. 414. Having glanced at the circumstances which attend and con-trol the production of flowers, and considered the laws which governtheir arrangement, we have next to inquire what the flower is com-posed of. 415. The Flower (117) assumes an endless variety of forms indifferent species, so that it is very difficult properly to define name was earliest applied, as it is still in popular languagegenerally applied, to the delicate and gayly colored leaves or petals,so different from the sober green of the foliage. But the petals,and all these bright hues, are entirely wanting in many flowers,while ordinary leaves sometimes assume the brilliant coloring of the 19* 222 THE blossom The stamens and pistils are the characteristic organs ofthe flower ; hut sometimes one or the other of these disappear from334 a particular flower, and both are absent from full double Roses, Camellias, &c, in which wehave only a regular rosette of delicate , however, is an unnatural state, the conse-quence of protracted cultivation. 416. The flower consists of the organs of re-production of a Phamogamous plant (114), andtheir envelopes. A complete flower consists ofthe essential organs of reproduction (viz. stamensand pistils), surrounded by two sets of leavesor envelopes which protect them. The latterare of course exterior or lower than the former,which in the bud they enclose. 417. The Floral Envelopes, then, are of two sorts, and occupy two circles, one above orThose of the lower circle,
