NATURAL HISTORY OF PLANTS. 



Onobri/chis saliva (Sainfoin). 



and on the other hand the true Sainfoins (Onobrychis; Fr., Esparcette), 

 with the flower and vegetative organs (fig. 1 82) of Hedysarum, but 



whose fruit (fig. 183) is reduced 

 to a single one-seeded joint, very 

 variably winged or muricated. 

 Ebenus has also an indehiscent 

 fruit reduced to a single joint. All 

 these genera constitute the sub- 

 series Enhedysarete. 



To these JEschynomenea comes 

 very near ; the flowers are here in 

 racemes (often few-flowered), cymes 

 or fascicles always axillary to the 

 leaves. These last are pinnate, 

 with usually numerous leaflets, 

 or rarely only from one to three. 

 In these flowers the wings are 

 often folded across, and the keel is 

 incurved, obtuse or beaked. The 

 stamens are either monadelphous, 

 or equally diadelphous (five on 

 either side of the flower). Un- 

 equal diadelphy (0-1) is very rare. 

 The style is slender filiform, usually 

 incurved. In this subseries are 

 placed the following genera : JEsc/iy- 

 nomenc, Her m in /era, Scemmeringia, Geissaspis, Smithia, Discolohhim, 



Ormocarpum, Isodesmia, Brya, Pic/din, Amicia, 

 Poiretia, C/tcsiocalyx, Nissolia, and (?) Ctenodon. 



The single genus Jdcsmia constitutes the little 

 group Adesmiea, or Hedysarea with free stamens. 



Bremontiera forms another little group. Here 

 the fruit finally separates into one-seeded joints 

 as in most Hedysarece, but the genus has the flowers 

 of Indiyofcrece ; the leaves are simple. 



Coronillcce are herbaceous, or rarely frutescent, 

 Hedysarece with pinnate, or rarely simple leaves 

 and axillary peduncles, supporting each a single flower, or a little 

 umbel. The stamens are diadelphous, and five have the upper parts
