Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . claws, which are enclosed in the tube of the calyx ; and the cruciate,or cruciform, which gives its name to the Mustard family, wherethe four unguiculate petals, diverging equally from one another,are necessarily disposed in the form of a cross, as in the Mustard(Fig. 405). Among the irregular polypeta- /7/1 ^J—\ lous flowers, which areextremely varied indifferent families, thepapilionaceous or but-terfly-shaped corolla of the Pulse family is the most familiar, andhas already been illustrated (471, Fig. 392). 510. Several forms of the gamopetalous corolla, or gamophyl-lous calyx, have been distinguished by particular names. Theseare likewise divided into the regular, where their parts are equal insize, or equally united; and the irregular, where their size or de-gree of union is unequal (471). Among the former are the cam-panulate or bell-shaped, as the corolla of the Harebell (Fig. 456),which enlarges gradually and regularly from the base to the summit;. the infundibuliform, or funnel-shaped, where the tube enlarges verygradually below, but expands widely at the summit, as in the corollaof Morning-Glory (Fig. 1035 and 452) ; tubular, where the form issomewhat cylindrical throughout, as in Trumpet Honeysuckle ; hypo-craterifarm (more correctly hypocraterimorphous), or salver-shaped, Rotate or wheel-shaped and five-parted corolla of the Bittersweet (Solarium FIR. ).FIR. 456. Wheel-shaped and five-cleft corolla of the common Potato. The almost entire and open bell-shaped corolla of a Ground Cherry (Physalis,). Campanulate corolla of the Harebell, Campanula rotundifolia. 45. Salver-shaped corolla of Phlox. 458. Labiate (ringent) corolla of Lamium ; a side view. 459. Per-sonate corolla of Antirrhinum. 460. Personate corolla of Linaria, spurred at the base. 24 278
