A FLORA OP GIBRALTAR AND THE NEIGHBOURHOOD 41 



red, not bright red fruit, and I suspect it is merely a form of that 

 species. III. i. San Eoque, Wk. ii. Algeciras, Wk. Mr. Druce 

 tells me he has seen it at the latter station. 



Pyriis communis L. var. Mariana Wk. Bushy hill slopes ; 

 occasional; 2-3. Only this variety is recorded. It differs in 

 spinescent branchlets, ovate or oval-subrotund leaves, and tur- 

 binate globose fruit on very thick peduncles. I have not seen 

 any named specimens ; my own agree very closely with P. cordata 

 Desf. in their small neat leaves, but that species is not recorded 

 for Spain. [I. The type cultivated, if.] III. i. East slopes 

 Chair, very small bushes almost buried in heather ! Alcadeza 

 Crags to Majarambout ! ii. S. de Luna about Algeciras, P. L. 

 iii. Sandy ground near Guadacorte Marsh ! 



■''Cydonia vulgaris Pers. is quite naturalized here and there, 

 as beyond Almoraima and Long Stables, remote from buildings, 

 also in Palmones Sands, small barren bushes looking quite native. 



[Primus Armeniaca L. and Eriobotrya japonica Lindl. are only 

 cultivated.] 



[Granatace^.] 



[Punica granatum L., as the remains of cultivation, looks 

 native in several places on the Rock and in Spain.] 



MYRTACEiE. 



Alyrtus communis L. Bushy places and woods; frequent or 

 common ; 6-7. III. i. Foot of Chair ! Alcadeza Crags ! Cork 

 Woods ! ii. Palmones Playazo ! iii. Palmones Sands !

 var. rather frequent ; 6-9. III. i. Behind Almendral, K. 



Var. tomentosum DC. More canescent, spikes dense, villous 

 tomentose. III. i. By Lajo in many places! Cork Wood Sotos! 

 ii. Palmones Playazo! Carnero Hills! iii. Guadacorte Marshes, 

 sometimes 6-8 ft. high ! 



L. Grceffcri Ten. (L. fiexuosiim Lag.). Damp grassy places, 

 roadsides, and ditches; very common ; 4-8. II.! III.! 



Var. Preslii Deb. Stem erect, simple, lower leaves rounded 

 or subcordate at base, upper narrow. II. and III., K., D. 



L. Hyssopifolia L. In drier places ; common ; 4-6. Annual, 

 flowers smaller, petals paler, 5-6, also stamens. II. ! III. i. and 

 ii. ! My 1196, from sands near Pedrera, is small, subsimple, 

 2-3 in. high, and looks different. 



L. thymifolia L. Dry light soil ; rare ; 5-6. Smaller and 

 more slender, petals very small, 4, stamens 2. III. i. Near San
