342 DIAUELPHIA. 



** Stigma downy ^ without the character of the pre- 

 ceding section, for this and all the following are truly di- 

 adelphous. Very nice, but accurate, marks distinguish 

 the genera, which are sufficiently natural. The style 

 and stigma afford the discriminative characteristics of 

 Orohus, t. 1153 ; Pisiun, t. 1046 ; Lathyrus^ t. 670, 

 1108 ; Vicia, t. 334, 481-— 483 ; and no less decisively 

 in Ervum, t, 970, 1223, which last genus, notwithstand- 

 ing the remark in Jussieu 360, ^^ stigma non barbatum,^-' 

 (taken probably from no genuine species,) most evi- 

 dently belongs to this section, as was first remarked in 

 the P/oj-a Britannica ; and it is clearly distinguished 

 from all the other genera of the section by the capitate 

 stigma hairy all over ; nor is any genus in the whole 

 Class more natural, when the hitherto mistaken species 

 are removed to their proper places. See FL Brit. 



*** Legume imperfectly divided into two cells, al- 

 ways, as in all the following, without the character of the 

 preceding sections. This is composed of the singular 

 Biserrula, known by its doubly serrated fruit, of which 

 there is only one species ; the Phaca^ Jacq. Ic. Par. t. 

 151 ; and the vast genus of Astragalus, Engl. Bot. t. 

 274, Sec, lately illustrated in a splendid work by an able 

 French botanist, Decandolle. 



**** Legume with scarcely more than one seed. Of 

 this Psoralea, Curt. Mag. t. 665 ; the curious Stylosan- 

 thes of Swartz ; the Hallia of Thunberg ; and our own 

 Trifolium, Engl. Bot. t. 1770, 1048—1050, are exam^ 

 pies. The last genus, one of the most natural as to
