History, Use, Propagation, Culture, 
of Persia, flowering in July and August. It rises two or three feet only in height, on a stem about an inch 
in thickness ; with many branches closely crowded to.gether, and covered with imbricated scales and spines, 
formed from the petioles of the former year. The leaves, whicli 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 axilla; 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. Iviii. 30.), or the oxysulphate of iron. Medically it is de-
