NEIGHBOURHOOD OF GIBRALTAR. 195 



with Leucojum tricophyllum, Brot., a plant which 

 grows in great profusion on the Spanish race-course, 

 near Gibraltar. Mr. W. also found in the marshes 

 near the Cape, among other plants common to the 

 whole of this district, Ranunculus paludosus, Desf., 

 growing plentifully, as also the Ranunculus flabella- 

 tus, which is a more common plant. Mr. Willkomm, 

 after describing the vegetation of hills near St. Roque, 

 observes of the hilly land near Algesiras, that it is 

 almost " exclusively covered with Calycotome villosa 

 (Spartium villosum) and a Genista ; patches of Cha- 

 mserops humilis are also frequently seen, and, more 

 seldom a Sarothamnus. On somewhat moist places, 

 and under bushes, grow everywhere Allium trique- 

 trum, L., and also Bellis sylvestris, Cyr., B. annua, 

 L., Ranunculus flabellatus, Rumex bucephalophorus, 

 a small blue-flowered Linum,* especially in the scat- 

 tered copses of Pinus picea, also Hedysarum coro- 

 narium, Z/., Ophrys apifera, Huds., more rarely, and 

 only on limestone, Ophrys lutea, Cav., several Carices 

 and grasses, Salvia Verbenaca, Anthyllis tetraphylla, 

 Calendula arvensis, Alyssum maritimum, Cerastium 

 glomeratum, Cerinthe major, Conigiola littoralis, &c. 

 Large patches were covered with Pteris aquilina, 

 especially along the foot of the mountains ; whilst in 

 the moist lowlands and marshes grew Juncus acutus, 

 Heleocharis palustris and Carices in abundance, and, 

 rarely, Alisma ranunculoides." This list may be consi- 

 derably increased by any botanist who can spare more
