1818.] GENLS GLYCINE. 333 



vexillum deflected apparently without the hifluence of 

 the carina ; and its legume^ which Linnaeus did not 

 note, nearly cylindrical, and coriaceous. Its legume, 

 howe\^er, forms its most important point of resem- 

 blance. 



The Glycine monoic a forms another anomalous spe- 

 cies ; in habit distinct, in the structure of the corolla 

 resembling some species of Yicia, and in its legumes 

 varying from the Glycine. Walter, whose accuracy of 

 observation merits more praise than it has yet receiv- 

 ed, while he was misled by the spiral carina, to place 

 two species of real Glycine with the Fhaseoliis, yet 

 perceived the discrepance between these two plants, 

 and the G, apiosy and has pointed them out as distinct 

 genera. 



A third plant, hitherto I believe undescribed, which 

 grows along the southern coast of Carolina and 

 Georgia, is connected with this group ; but as I wish 

 to compare further, if possible, its affinities with 

 some foreign genera, I shall, for the present, postpone 

 its consideration. 



I can readily perceive, that the arrangement I have 

 proposed, will i^equire the removal of many of the ex- 

 isting species ofPhaseolus and Glycine^ yet the result 

 I hope, will be, that those which remain in each ge- 

 nus, will be plants which nature, and not man, has 

 chosen to associate. So many corrections and modi- 

 fications of the genera established by Linnaeus, have 

 been made as the knowledge of plants has become 

 more extensive, that all appear to require frequent re- 

 vision ; and it may become necessary, in the class we 

 nre now examining, to consider the spiral style and
