It rises two or three feet only in height, on a stem about an inch in thickness; with many branches closely crowded together, and covered with imbricated scales and spines, formed from the petioles of the former year. The leaves, which scarcely exceed half an inch in length, are composed of six, seven, or eight pairs of opposite, villous, stiff, pointed leaflets; and the mid-rib is terminated with a sharp yellowish point. The flowers are small, yellow, and proceed from the axillæ of the leaves with cottony bractes. The calyx is five-toothed, and shorter than the corolla, which is papilionaceous. The gum exudes in summer, more or less copiously according to the heat of the weather, in tortuous filaments, , which are allowed to dry on the plant before being collected. A large portion of the Tragacanth collected in Persia, is sent to India, Bagdad, Bassorah, and Russia. But what we receive is sent to Aleppo, whence it is exported, packed in cases.

Good gum Tragacanth is inodorous; impressing a very slightly bitter taste as it dissolves in the mouth. Its mucilage differs from that of acacia gum, in being precipitated by the superacetate of lead, and oxymuriate of tin ; and not by silicated potass (Bostock. Nich. Journ. lviii. 30.), or the oxysulphate of iron. Medically it is de- ORDER IV.

It is chiefly, however, employed for pharmaceutical purposes. (Thomson's London Dispensatory, 187.) The seeds of A. boeticus are , 187.) The seeds of A. bæticus are roasted, ground, and used as a substitue for coffee in Hungary . 1595. Biserrula. From bis, twice, and serrula, a little saw. The pods are toothletted on each edge. Pelecinon was the name given by the Greeks to the plant called by the Latins Securidaca. 1596. Dalea. Named after Thomas Dale, an English botanist, who lived in the beginning of the last century. There was another Dale, an author of a Pharmacologia. These are pretty little plants, with the aspect of Psoralea. 1597. Psoralea. From ψωρaλεoς, warted, on account of the numerous little tubercles with which most of the species are covered. The species are chiefly low shrubs; some of them are ornamental, and all are of easy culture and propagation by young cuttings in sand or seeds, which they produce in abundance.
