Considering their crowded state in the flower, we rather wonder that they do not always coalesce in their growth. 458. The calyx with united sepals was called by the eaily botanists monoisepalous ; the corolla with united petals was called tnonopetaloun {jxovog, one—from the false idea that such an organ consisted of a sin- gle piece or leaf!). Opposed to these terms were polypetalous {jrokvg^ many), petals distinct, and polysepalous, sepals distinct. 459. The monosepalous calyx, or monopetalous corolla, al- though thus compounded of several pieces, is usually described as a simole organ, wheel-shaped, cup-shaped, tubular, according to the de- grto of cohesion. The lower part of it, formed by the united claws, whether long or short, is the tube ; the upper part, composed of the confluent laminae, is the border or limb ; the opening of the tube above is the throat. 460. The border is either lobed, toothed, crenate, etc., by the dis- tinct ends of the pieces composing it, as in the calyx of pink, the calyx and corolla of Primula, Phlox, and bellwort, or it may become by a complete lateral cohesion, entire, as in morning-glory. Here the com pound nature of the organ is shown by the seams 800, Flower of Saponaria (bouncing bet); petals and claws quite distinct. 3(il, Phlox; clawl united, with lamina distinct. 302, 8i)igelia (pink-root), petals still further united. 808, Quamo- clit coccinea, petals united throughout. 461. A terminal cohesion, where summit as well as sides are joined forming a cap rather than cup, rarely occurs, as in the calyx of the garden Escholtzia and the corolla of the grape. 462. The modc
