as evidence against this it must be pointed out that the supposed 

 hybrid shows an arborescent habit, altogether lacking in the parents, 

 nor are there any clear data as to the presence of both supposed 

 parents at the locaHty, at which 5". arborea is found. The author 

 admits the hybrid character of the Orotava garden pkint, which con- 

 stitutes Perez's evidence, but considers the parents to be typical

 is now extinct; it inhabited during the last llOyears two very small 

 areas (Burgado Cove andDautd) on the N. coast ofTeneriffe, 

 whilst a third equally small area on the El Freyle, still harbours 

 a much stunted form of this species (S. arborea f. fnitescens = vS. 

 frntescens). The cultivated specimens of 5". arborea (at Teneriffe 

 and Kew) are descendants of the extinct species with a distinct 

 strain of 5". macrophylla. F. E. Fritsch.
