GIBRALTAR PLANTS. 93 



Sarothamnus boeticus, Boiss.

 Hab. South of Spain. Barbary. 



OBS. This species, known also as the Cytisus arboreus of Salzm.

 it, I shall quote here Boissier's remarks on this elegant species. 

 " Petite plaute de 1 a 2 pieds de haut, a epines rameuses, 

 courtes, nombreuses et un peu courbees ; a feuilles lineaires, et 

 le plus souvent changees aussi en epines. Elle est voisine du
