. Botany for beginners: an introduction to Mrs. Lincoln's Lectures on botany. Plants. 138 BOTANY FOR BEGINNERS. Cji. XXU1. Class XL Icosandria, more than ten stamens inserted on the calyx. Order 1. Monogynia, one pistil. 5S2. In this class, the number of sta mens is not regarded, so much as their situation. If you remember what was said about the rose in the 4th chapter, you will understand what is the essen- tial character of this class. The rose, however, does not belong to the first • order. 583. In this order we find a genus called Cactus, one of the species ol which is the Prickly-pear. This con- tains many species ; a very splendid one is the Night-blooming Cereus, (Cactus grandijlorus,) having flowers nearly a foot in diameter, with the ca- lyx yellow, and the petals white ; the fknvers begin to open soon after the setting of the sun, and close before its-rising, never again to blossom. Another species, (speciosissimus,) with flowers of the colour of crimson velvet, is said to be still more superb than the grandiflorus. These plants are mostly destitute of leaves, but the stems appear like a series of thick, fleshy leaves, one growing from the top of another. 5S4. Pruniis is the genus which contains the various kinds of the Plum, Cherry, and Sloe: this genus, according to ancient writers, was brought from Syria into Greece, and from thence into Italy. The Roman poets often notice its fruit. We have several native species of it. 585. The Pomegranate is a shrubby tree, which is a native o* Spain, Italy, and Barbary, and flowers from June till September. The Greek writers were acquainted with it, and we are told by Pliny, that its fruit was sold in the neighbourhood of Carthage. It is cultivated in England and in the United States ; not on ac- count of its fruit, which does not come to perfection so far to the north, but for its large and beautiful scarlet flowers, which render it an ornamental plant. 582.
