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



Bromus giganteus, L. Woody region of Etna, J. B. ? 



asper, L. I suspect that this and the preceding species, and 



possibly the following one also, will ultimately be placed in the 



same group with Triticum ciliatum, DeC. 



erectus, Huds. The extreme forms of this species are at least 



as distinct as Festuca pinnata, Huds., and F.phamicoides, L. 



sterilis, L. 



/3. argentea. Coast near St. Alessio, J. B. sp. I 



know not on what authority Bertoloni has united the B. jubatus, 

 Ten., with this species. 



scaberrimus, Ten. 



maximus, Psl. 



-, /3. (B. madritensis, Guss.). This latter is considered 



distinct by Professor Parlatore, who has well illustrated the Sici- 

 lian species of this genus. A great variety of forms exist in the 

 island, but I can only separate my specimens into two specific 

 groups, and even of these the limits are not very well defined. 

 The synonymy is in inextricable confusion. 



tectorum, L. Frequent. 



— rubens, L. Val di Mazzara and hills about Palermo, Guss. 

 -fasciculatus, Psl. Near St. Alessio and Selinonte, J. B. sp. ; 



Val di Mazzara, Gussone : a very distinct species. Had I not been 

 desirous of avoiding unnecessary change in a mere catalogue, I 

 should have followed Prof. Parlatore in separating the Bromi seca- 

 lini as a distinct genus, to which he has given the name Serra- 

 f ulcus, in the small monograph already referred to. 



Stipa pennata, L. Hills of Termini and Altavilla, Gussone. 



capillata, L. Terranova, Castelvetrano, Gussone. 



tortilis, Dsf. Frequent, J. B. sp. 



Aristella bromoides, Bertoloni (Stipa Aristella, L.). Not unfrequent, 

 J. B. 



Avena sterilis, L. 



fatua, L. 



fallax, Ten. Hills about Palermo and Caltavoturo, Gussone. 



pubescens, L. Sicily, J. B. ? 



pratensis, L. Frequent, J. B. 



condensata, Link. In many places on the coast, J. B. sp. 



neglecta,\Savi. Terranova, Gussone. It is admitted that most of 



the characters which separate this and the preceding are variable. 



parviflora, Dsf. 



, flavescens, L. (To this Bertoloni refers Trisetum splendens, Psl.) 



fragilis, L. (Gaudinia fragilis, R and S.). Common, J. B. 



Danthonia provincialis, DeC. Lower region of Etna, J. B 

 Lagurus ovatus, L. Very common. 

 Arundo Donax, L. 



pliniana, Turr. Chiefly about Palermo. This is the A. mau 



ritanica, Dsf., of Mr. Hogg. 



Ampelodesmos, Cyr. Common. 



Phragmites, L. 



epigejos, L. 



montana, R. and S. Etna, J. B. ?
