Introduction to structural and systematic botany, and vegetable physiology, : being a 5th and revedof the Botanical text-book, illustrated with over thirteen hundred woodcuts . in the Southern acrid and bitter principle pervades this tropical order. 781. Ord. Cedrelaeese (Mahogany Family). Trees (tropical orAustralian), with hard and durable, usually fragrant and beautiful 34* 402 ILLUSTRATIONS OF THE NATURAL ORDERS. wood ; differing botanically from Meliacere chiefly by their capsularfruit, with several winged seeds in each cell. — Ex. The Mahogany(Swietenia Mahagoni) of tropical America, reaching to East Flor-ida. Bark, &c. bitter, astringent, tonic, often aromatic and Old. Liliacete {Flax Family). Herbs, with entire and sessileleaves, either alternate, opposite, or verticillate, and no stipules, ex-cept minute glands. Flowers regular and symmetrical. Calyx ofthree or five persistent sepals, strongly imbricated. Petals as manyas the sepals, convolute in aestivation. Stamens as many as thepetals, and usually with as many intermediate teeth representing anabortive series (Fig. 423), all united at the base into a ring, hypogy-. nous. Ovary with as many styles and cells as there are sepals,each cell with two suspended ovules ; the cells in the capsule eachmore or less divided into two, by a false par-tition which grows from the back (Fig. 750) ;the spurious cellsone-seeded. Em-bryo straight:cotyledons flat,fleshy and oily,750 surrounded by a thin albumen. — Ex. Linum, the Flax,the bark {flax) is of the highest importance: the seeds yield acopious mucilage, and the fixed oil expressed from them is appliedto various uses in the arts. The general plan of the flower is thesame in the succeeding orders.
