Ttese 202 genera, wMch are absent in tte Canaries, com- 

 prise upwards of 300 Maroccan. species, including Eryngium, 

 ■with eleven species, Coronilla -with eight, Diplotaxis with seven, 

 Narcissus, Anthyllis, Polygala, Passerina, and Quercus five 

 each, besides twenty other genera with three or four each. Not 

 a few of them contain very common and wide-spread species, as 

 do all the above-named, as well as Clematis, Malcolmia, Gar- 

 damine, Dianthus, Hedysarum, Heradeum, Asperula, Achillea, 

 Onopordon, Hyoseris, Scorzonera, Phyllyrea, Fraxinus, Galy- 

 stegia, Anarrhinum, Ballota, Populus, Ghanwerops. That no 

 species of these or of many of the other genera should exist in 

 the Canaries is inexplicable, considering the position and extent 

 of the Archipelago, and the means of migration which must 

 exist between it and the mainland. 



The species common to Macaronesia and Marocco exclu- 

 sively, are in so far as is at present known : — 



Eelianthemum canariense, Jacq. 



Polycarpia nivea. Ait. (also occurs 

 in 0. de Verde) 



Zygophylltun Eontanesii, Weii 



t Cytisus albidus, DC. 



Ononis angustissima, Lam. (? A 

 form of 0. Natrix) 



Astragalus Solandri, Lowe (Ma- 

 deira only) 



Astydamia canariensis, D G. 



Bowlesia oppositifolia 



Odontospermum odorum, Schousb. 



Sonchus acidus, Scluiusi. (In Lan- 



cerotte, only a single plant, 



possibly introduced) 

 Lithospermum microspermum, 



Boiss. 

 Linaria sagittata, Pair. 

 Chenolea canariensis, Moq. 

 Salix canariensis, Chr. Sm. (rather 



uncertain) 

 Romulea grandiscapa, Webb. 



(Perhaps only a var., but Baker 



keeps it) 

 Asparagus scoparius, Z<me. (Not 



quite certain)

 questions raised by this slight sketch of the peculiarities of the
