Here are near upon 90 species or genera, and almost half of them are 

 identical with a few proximately related species. Most of them affect 

 the Chilian side of the continent One or two are known only on the 

 era side. The mosl remarkable of these arc the QaiUardia and the 

 ma, of Buenos Ayres; the former closely related to an equally 

 anomalous Texan species ; the latter almost identical with a Texano Ne 

 braskan species. One of the Strombocarpa species of Prosopis, of the 

 * athera end of Texas, is hardly and perhaps not specifically distingnisfa 



from one of Buenos Ayres. or the lOor more identical spe< 

 only 17 belong to the Atlantic flora ; apparently only two of thea
