Mr. J. Ball on the Botany of Sicily. 349 



Festuca alopecurus, Pers. I have specimens from near Messina agree- 

 ing with the plant so named by Tenore. 



incrassata, Salz. Sea-shore at Girgenti and Alicata, Gussone. 



poaformis, Spr. Sands of Etna, Gussone ; Madonie, Jan. 



ovina, L. I am quite of the opinion of Bertoloni, * Flora Ita- 



lica,' i. 601, in uniting this with F.duriuscula, L., and the various 

 supposed species there mentioned, but am inclined to consider the 

 following as distinct. 



rubra, L. I am quite sure that I observed the large sea- side 



form of this plant on the east coast of Sicily, J. B. 



heterophylla, L. Woody region of Etna, Gussone. The cha- 



racters of this species remain very constant in cultivation. 



exaltata, Psl. 



calamaria, Sm. Woods of Etna, J. B. ? 



pratensis, Huds. Sicily, Gussone. 



fii (F. elatior, L.). Coast near Syracuse, J. B. sp. 



I am unable to find any permanent characters by which to separate 

 these extreme forms, which are connected by many intermediate 

 varieties. 



serotina, L. 



cterulescens, Dsf. Mountains near Palermo, Val Damone, 



Gussone. 



cristata, L. (Kceleria phleoides, Pers.). Frequent, J. B. sp. 



hispida, Savi. Castelvetrano, Bronte, Gussone. 



Sinensis, Psl. Lower region of Etna. This plant should be 



sought for, as it seems little known ; Bertoloni believes it to be 

 nearly allied to or identical with Poa cenisia, All. 



gracilis, Mcench. (^Brachypodium sylvaticum, R. and S.). On 



Etna, J. B. ? 



pinnata, Huds. (Brachypodium pinnatum, R. and S.). Fre- 



quent, J. B. sp. 



phoznicoides, L., Mant. Frequent, J. B. sp. Extremely near 



the last species. 

 Bromus secalinus, L. 



-, /3. (B. velutinus, Schr.). Polizzi, Gussone. 



■ squarrosus, L. 



mollis, L. It occurs both in the pubescent and glabrous 



form. 



racemosus, L. (B. arvensis, Sm.). Bertoloni is probably cor- 

 rect in referring the B. arvensis, E. B., to B. racemosus, L. ; but I 

 believe that the plant named B. racemosus by Smith and most 

 English botanists is the glabrous form of B. mollis before men- 

 tioned. B. commutatus, Schrad., should probably be referred to 

 the present species. The B. arvensis of the Italian botanists, and 

 perhaps of Linnaeus, is certainly different from the English species. 

 intermedius, Guss. Boccadifalco, &c, Gussone. This is not 



unlikely to prove a variety of B. mollis. 



lanceolatus, Roth. Not unfrequent, J. B. sp., and certainly 



distinct. 



scoparius, L. Terranova, J. B. sp. ; Palermo, Val di Maz- 



zara, Gussone. This species has been much confused ; it is nearly 

 allied to the last.
