Perhaps the most remarkable feature of this list, so far as it goes, 

 i« the large proportion of species characteristic of the hill districts of 

 Central Europe. Hooker and Ball noted the same fact in connection 

 with the mountain flora of the Great Atlas further south. It may 

 therefore be regarded as definitely established that there is a very 

 close connection between the flora of the whole range and that of the 

 hills and mountains of Europe. 



The botany of the Lesser Atlas and the other mountain-masses of 

 Algeria is pretty well known, thanks to the researches of Battandier and 

 Trabut ; and all the plants found by Captain Lynes, with the exception 

 of nine or perhaps ten, are recorded by those authors in their Flore de 

 V Algerie. On the other hand, all we know of the flora of the Great 

 Atlas is derived from Hooker and Ball's Journal o^ a Tour in 

 Marocco and the Great Atlas (1878), and a collection of plants 

 made by J. Thomson in 1888 which is preserved at Kew. Of the 

 plants recorded in Ball's paper on "The Mountain Flora of Two 

 Valle^'S in the Great Atlas " in Appendix G to the Journal, only 88 

 were refound by Captain Lynes in the Middle Atlas, and only 25 

 of Thomson's list. It should, however, be remembered that both 

 Ball and Thomson were able to penetrate into the upper regions above 

 6000 feet, which Captain Lynes found it impossible to reach. 



The following plants require a special note : — 



Potentilla hispanica Zimm. This is the plant which Willkomm 

 and Lange call P. pennsylvanica L., and has been recorded under that 

 name from Southern Spain and Marocco. But Wolf in his Mono- 

 graph of Potentilla has shown that this was a mistake, and that 

 there are three related, but distinct, plants with different areas of 

 distribution: — (1) P. pennsylvanica L. North America and East 

 Siberia. (2) P. sibirica Wolf. Asia. (3) P. hispanica Zimm., 

 which is found in South Spain (1500-1800 metres), and the moun- 

 tains of Algiers, Marocco, and Abyssinia, with a variety in the 

 Caucasus. The material at the British Museum and at Kew bears 

 out his conclusions. It is a very showy species.
