Kunze (" Monographie der Gattung Clematis" in Verhandl. Bot. Vereins Brandenb. 

 xxvi. pp. 83-202) reduces the forms included in our enumeration to four species, and 

 this is perhaps the best way of dealing with them. Thus C. dioica, Linn., includes 

 C. acapulcensis, Hook, et Am., C. americana, Mill., C. caripensis, H. B. K., C. earaca- 

 sana, DC, C. drummondii, Torr. et Gray, C. flammulastrum, Griseb., G. grahami, 

 Benth., C. grossa, Benth., C. moginiana, Don., G. nervata, Benth., G. polycephala, Bert., 

 G. pubescens, Benth., and C. sericea, H. B. K. ; C. pauciflora, Nutt., is reduced to 

 C. lasiantha, Nutt., a common Californian species; Cfilifera, Benth., and C. pitcheri, 

 Torr. & Gr., are referred to C. simsii, Sweet (C. cordata, Sims, Bot. Mag. t. 1816), a 

 species ranging from Mississippi State to Mexico ; finally, C. reticulata, Walt., is 

 reduced to C. viorna, Linn., which, as circumscribed by Kunze, has a wide range in 

 Eastern North America, and also occurs in Amur -land.

Illinois to Texas. — Noeth Mexico, Coahuila (Palmer) ; South Mexico, Guanajuato 

 (Luges). 



Watson regards C. filifera, Benth., as a synonym of this. 



t This does not profess to be complete, but is intended to include as nearly as possible all the new facts 

 bearing upon the distribution of the plants of Mexico and Central America. There is a very considerable 

 number of new species from Forth Mexico, as well as an extension of the range into Mexico of many addi- 

 tional Texan and New Mexican species.
