numerous genus, not remarkable for beauty, but containing two curious species, the manna plant, and the 
turning Hedysarum ; and one of considerable importance in European agriculture, the Saint-foin. 
H. Alhagi is a thorny shrub, with lanceolate leaves, and coriaceous, subcylindric, and scarcely jointed 
pods. It is on this plant that Manna Trungebeen is found in Mesopotamia {Russ. Alepp.) and other eastern 
countries. It is chiefly gathered about Tauris, where the shrub grows plentifully. Sir George Wheeler 
found it growing in Tinos ; Tournefort also found it in many plains of Armenia and Georgia, and made a 
distinct genus of it, under the name of Alhagi, from the Arabic Aghul or Al-gul. 
H. gyrans is a native of Bengal near the Ganges ; and is called there Buram Chadali, or Burram Chandali. 
This is a wonderful plant, Linnaeus observes, on account of its voluntary motion, which is not occasioned by 
any touch, irritation, or movement in the air, as in Mimosa, Oxalis, and Dionjea ; nor is it so evanescent as in 
Amorpha. No sooner had the plants raised from seed acquired their ternate leaves, than they began to be in 
motion this way and that ; this movement did not cease during the whole course of their vegetation, nor were 
they observant of any time, order or direction ; one leaflet frequently revolved, whilst the other on the same 
petiole was quiescent ; sometimes a few leaflets only were in motion, then almost all of them wouid be in 
movement at once : the whole plant was very seldom agitated, and that only during the first year. It con- 
tinued to move in the stove during the second year of its growth, and was not at rest even in winter. {Supp. 
Linn.) Swartz observes, that the motion is irregular, and that it sometimes ceases entirely ; that in a very 
hot day it is immoveable, being agitated only in the evening, and that slowly. In our climate, the leaves, in
