where Tennessee, North Carolina, and Georgia interlock and runs north- 

 ward through Eastern Tennessee and Western N. Carolina. Here are 

 discovered many forms from the north, having found in the elevations 

 of the mountains compensation for a more southern latitude, no fewer 

 than 65 such species being noted in this supplement. Speaking of the 

 northerners we remark the occurrence of Hedtim RJwdiola in the Mts. 

 <>f N. C., which was found years ago clinging to a cool cliff near Easton, 

 Penn., and taken as an example of a stranded glacial visitor. Asplenium 

 rbenoides, too, has been found in shady ravines in central Alabama, and 

 TSrythronium albidum upon the very summit of lloan Mountain. The 

 Mississippi river has also kept up a movement of species southward and 

 its influence is very noticeable in glancing over this supplement. Nat- 

 urally the West has not contributed so many forms as either the South 

 or North, for the barriers in that direction are greater. We note, how- 

 ever, about 25 species which may be considered to have come from the 

 West. These figures of course only apply to the supplement, and in a 

 study of the original Manual it will be seen that this composite flora is 

 tinged more from the north than from the south on account of the 

 greater ease of communication in that direction; while the western 

 forms still remain in the background. Some 15 species are published 

 here for the first time, 10 of them bearing Dr. Chapman's name as au- 

 thor, and 12 of them from Florida. They are an Alsine, Poly gala, Peta- 

 lostemon, Ludwigia, Pinguicula, two Euphorbias, Croton, Tillandsia, 

 Xyris, Cyperus, Rhynchospora, two Paspalums, and an Andropogon. 

 Two orders for the first time find place in our Flora, namely, Casumrinem 

 and Piperacece, containing together 3 species, all from Florida.
