be correct in distinguishing this from the A. Ischcemum, L., the 

 common French species, it will be necessary to rename the A. an- 

 gustifolium, H. and K., a Mexican species, which ought then to 

 recover the name A. stenophyllus, II. and S. Syst. Nat. 



Andropogon pubescens, Vis. I found this species, which is nearly allied 

 to A. hirtum, L., on dry rocky ground near the monastery of San 

 Martino, seven miles from Palermo. It is widely spread along the 

 coast of Barbary, and has been found in Abyssinia and Nubia by 

 Schimper and Kotschy.

Bauhini, W., J. B.} These three species are very nearly al- 

 lied ; with the assistance of Bertoloni's remarks, both groups may 

 be well studied in Sicily. If great difference of habit suffices to 

 constitute a genus, these might well be separated.

of uniting all these supposed species, as well as the S. elongata,W., 

 into one. The above forms, with many intermediate ones, will be 

 found in Sicily. The var. e. has been found in the mountains of 

 Madonie and Cammarata by Gussone.
