POLYGAL.E AMEBIC \NyE. 205 



H.B. K.), and P. Beyrichii, Torr. and Gr., i., 130. It extends as 

 far north as Missouri (Geyer, 276), and occurs also as follows : — 

 Texas, Wright, 99, Drummond, 4, 17, Liudh, 220 ; Mexico, Coult., 

 725, Hartw., 80. 



P. scoparia,}!. B. K., v., 399 ; DC, Prodr., i., 329 (non Benth.), 

 has a more rigid and more branched stem, the racemes are laxer, 

 and the lower flowers often x^endent after flowering. Only in a few 

 cases can any mistake be made between the two. This species is 

 decidedly more southern than the last, scarcely passing into the 

 United States Territory. It occurs in Mexico, Bott., 823. (Orizaba), 

 and Coult., 726; New Mexico, Wright, 70, 100, and 1348; and 

 Mexican Boundary Survey,. 193. The var. multicaulis is P. 

 Wrightii, Gray, MS. 



Seemann (Bot. Her. 269) has introduced further confusion into 

 these species by erroneously identifying P. bicolor, H. B. K., with 

 P. aparinoides, H. & A., P. asperuloides, H. B. K., P. distans, St. 

 Hil., and P. molluf/mifolia, St. Hil., all of which have verticillate 

 leaves, while this is never the case with P. alba or P. scoparia. 



Sectio G. Carina cristata ; folia alterna, nunquam verticillata, 

 elliptica vel latiora ; semina stro'phiolata,. biappendiculata. Herbas. 



The least satisfactory of all the six divisions, made up of those 

 which cannot be included in any of the previous five. It will 

 probably be broken up or altogether abandoned when all the Ame- 

 rican Polygalas Come to beproperly monogra[ bed. In the ' Flora 

 Brasiliensis' I have included eleven species in this section ; and 

 with them must probably be associated nearly all the North 

 American species, except P.grandijiora and those with verticiUate 

 leaves or leafless stems. 



The following species of Polygala, recorded as inhabitants of 

 America and the West Indies, are not included in the foregoing 

 enumeration. I have not had access to type-specimens, and the 

 descriptions are in most cases too incomplete to admit of their 

 identification, or otherwise, with known species.
