36 BET. H. T. LOWE'S LTST OF PLANTS 



Madeira, in correspondence with the geographical position of the 

 place. 



In confirmation of this last deduction, it appears, so far as may 

 be concluded from this list, that whilst Mogador has 37 or 38 

 plants in common with Algeria alone, it has only 4 or 5 peculiarly 

 Canariau, and not one peculiar Madeiran plant. 



The relative numbers or proportions of species in the different 

 families or orders range as follows : — 

 Composites 20, or about \. 

 Leguminosce 13, or about y 1 ^. 

 Graminaceoi the same. 

 Labiates 10, or y^. 

 Scrophulariacece 7, or about ^.

 Of single genera, Plantago has the greatest number of species. 

 In the foregoing list the names of several unrepresented orders, 

 belonging to the Canarian and Madeiran Floras, are inserted ior 

 the mere sake of comparison. 



Notes on particular species in the preceding list. 



No. 2. Delphinium macropetalum, DC. Syst. i. 350 ; Prodr. i. 

 53. — Flowers full, rather than deep, blue. Ovaries 3. Two lower 

 petals stipitate, the limb orbicular-obovate, and gradually atte- 

 nuated at the base into its stalk. 



The habitat " circa Mogador, Broussonet," ascribed by De 

 Candolle in the former of the works above quoted to his D. macro- 

 petalum, agrees no less than his description with my plant, which 

 I found commonly in waste garden-ground or cornfields up the 

 river, three or four miles from Mogador. It seems to differ scarcely, 

 even varietally, from D. junceum, DC. = D. peregrinum, Desf. i. 

 426 ? ; Sibth. Fl. Gr. t. 506 ; Keichenb. Ic. Fl. Germ. iii. t. 68. 

 f. 4672 (not Linn. !). It has perhaps, however, more the lax 

 spreading or straggling habit of D. Consolida, L., though the main 

 stem is erect. 



5. Fumaria agraria, Lag. (not Koch.). — Habit of F. officinalis, 

 L., but larger, with stouter stiffer stems. Fl. rather large, 4-6 

 lines long, full rose-purple tipped with black ; sep. ovate toothed 

 A- length of cor. Fr. large, distinctly verruculate, orbicular com- 

 pressed, strongly carinate, with a distinct broad compressed short 

 truncate or slightly notched beak. 



This agrees exactly with F. agraria, Lag., of the Hookerian
