 are disposed in an almost naked terminal raceme. Stipulas 

 joined, opposite the leaves. The plant in this section is very 

 different in habit from those species contained in the first sec- 

 tion, but the character of the fructification is very similar.

CLVIII. HEDY'SARUM (iitiwapov, hedysaron, is the name 

 of a plant of Theophrastus and Dioscorides ; said to be from ?;oi>e, 

 hedys, sweet, and apw/ia, aroma, perfume. The present genus, 

 however, has nothing to do with the plant of Theophrastus, fur- 

 ther than belonging to the papilionaceous tribe. His plant being

LIN. SYST. Diadelphia, Decdndria. Calyx 5^-cleft ; the seg- 

 ments linear-subulate and nearly equal. Corolla with a large 



vexillum and obliquely truncate keel, which is much longer than 

 the wings. Stamens diadelphous, having the staminifcrous tube 

 abruptly infracted. Legume constantly of numerous, flat, orbi- 

 cular or lenticular, regular, 1-seeded joints, which are connected 

 together in the middle, and therefore the sutures are convex on 

 both sides Herbs or subshrubs, with impari-pinnate leaves, 

 axillary, simple peduncles, bearing racemose spikes of large, 

 purple, white, or cream-coloured flowers. This genus is nearly 

 allied to Onobrychis, but differs in the legumes being of many 

 joints, not of one joint only as in that genus. All the species 

 are very elegant when in blossom.
