GIBRALTAR PLANTS. 127 



olive and vine are seen flourishing in great perfection. The 

 var. /3. sylvestris is frequently met with on the higher parts of 

 the rock of Gibraltar. About the origin of the cultivated 

 olive, Boissier observes that the var. sylvestris " n'est pas le 

 type sauvage de 1'espece, mais une simple forme venue d'olives 

 cultives et dissemines au hasard. L'olivier n'est spontane 

 dans aucune partie de 1'Europe, et tire son origine d'orient." 

 And in another place he observes, that " la variete sauvage 

 differe de la forme cultivee par un tronc plus court, des rameaux 

 spinescents et un peu quadrangulaires, des feuilles plus etroites 

 et plus courtes, moms blanchatres a la surface inferieure, des 

 fruits plus petits." 



Phyllirea media, L. 

 Hab. South of Europe. North of Africa. 



OBS. Some authors have united the genus Phyllirea with Olea, 

 from its strong resemblance to the wild olive ; the plant in Gi- 

 braltar has been frequently mistaken for it. 



APOCYNE^l, R. Br. 



Vinca media, L. et Hoffin. fit i^<^^i^n ^ 



V. acutiflora, Bertol. 

 Hab. South of France, Portugal, Spain. North of Africa. 



OBS. This beautiful plant adorns the hedges and sides of the 

 walks in the Alameda ; it is likewise found on the higher parts 

 of the rock. Boissier observes that this plant was for a long 

 time confounded with the V. major, Z,., and that he has not 

 seen the V. major in any part of Spain. This plant is known 

 also in Gibraltar as the V. major. The V. rosea is cultivated 

 in gardens, and grows as luxuriantly as I have seen it in 

 Ceylon. 



Nerium Oleander, L. 

 Vulg. Adelfa. 



Hab. Mediterranean region of Europe, &c.
