120 A FLORA OF GIBRALTAR AND THE NEIGHBOURHOOD 



Spain's Chair! (2157). Found there also by Eeuter, teste 

 Hackel. 



■\F. montana M. Bieb. var. altissima Hack. {F. exaltata Wk. 

 non PresL). Stony slopes; very local; 6-7. A very large and 

 tall species. III. ii. At and above Waterfall ! Hackel and 

 Eeverchon have also found it there. 



F. ccBvulescens Desf. Stony and bushy slopes ; locally com- 

 mon ; 4-6. Stem-leaves flat, the radical often setaceous, densely 

 covered at base of stem with remains of old sheaths. III. i. 

 S. Carbonera, Hack. Majarambout Woods ! ii. Plentiful slopes 

 beyond Waterfall ! 



F. arundinacea Schreb. var. mediterranea Hack. Damp clayey 

 spots; frequent; 4-6. Awn fi'equently not terminal. I. Europa 

 Glacis, on dry rocks, rare ! III. i. Marshy ground near Pinda- 

 lista! (1195). iii. By Los Barrios Station! (2064). Seen in 

 many other places, but doubtful between this variety and next. 



Var. Fenas Hack. (F. intcrrupta Desf.) is probably as frequent 

 as last. III. i. Lajo Valley near upper ford ! Gibraltar, Fritze. 

 Almost certainly in this subdistrict. 



Bromus tectorum L. ? Eocky slopes ; rare or error ; 4-6. 

 Panicle drooping, rather dense, spikelets smooth, awn about as 

 long as pales. I.? D. Not confirmed. 



B. sterilis L. Eough grassy places ; occasional '? 4-6. Very 

 like B. 7naximus var. Gussonei, but decidedly smaller, with 

 shorter awns. I. Eeclamation Eoad ! Charles V.'s Wall ! and 

 probably elsewhere. III. ii. El Cobre ! Doubtless much more 

 frequent than these records show. 



B. maximus Desf. Sandy ground ; common ; 3-5. The type 

 has pale green very shortly pedicelled spikelets, with very long 

 awns. Either this or the next species is common, but their 

 differences are obscure, and the two have been much confused. 

 I. ! Specimens from Catalan Bay (884 and 1157) have fascicled 

 bulbs at the roots, but Dr. Stapf thinks they are only a state of 

 the type. III. ! 



Var. Gussonei Pari, is much more diffuse and lax, resembling 

 B. sterilis. It appears to be the commoner form, at least in 

 Spain. III. ! 



fVar. glaber Wk. is a dwarf, few-flowered variety, with glabrous 

 and shining spikelets. III. i. Near Gibraltar, Wk. 



B.madritensisDesi. Similar places; frequent? 3-5. Smaller 

 than last with shorter awns, spikelets usually purple. I. Brouss I 

 Willis's Eoad ! III. No actual records, but it certainly occurs, 

 and is abundant in the province. 



Var. ciliatus Guss. has a dense subthyrsoid panicle, with softly 

 pubescent, not scabrid glumes. I. Catalan Bay ! 



B. ruhens L. Similar places; occasional; 3-5. Panicle denser, 

 rigid, reddish, spikelets subsessile. I. South and west slopes, K., D. 

 III. i. San Eoque, Boiss. 



i Serrafalcus commutatus Godr. Grassy places, partial to shade ; 

 occasional or frequent ; 4-6. Panicle large and lax, often drooping, 

 pedicels long. III. i. Almoraima Soto ! ii. Hills south of Alge-
