MR. J. BALL’S SPICILEGIUM FLORH MAROCCAN®. 293 
short walk along the shore near that town, and add two or three 
species to our list of the coast-flora. 
On reaching Tangier Dr. Hooker’s engagements forced him to 
proceed at once to Gibraltar, and thence return to England. I 
was enabled to spend one day at Tangier, and after an absence of 
not quite two months found the aspect of the vegetation wonder- 
fully altered, since the appearance of a large number of species not 
before seen gave the neighbourhood an aspect of complete novelty. 
The flowers of the Cisti had disappeared; but in their place were 
many Composite and Labiate and other summer-flowering species. 
The most conspicuous was the magnificent Salvia bicolor, which at- 
tains a height of 7 or 8 feet, each of its numerous branches bearing 
the conspicuous white-and-blue flowers to which it owes its name. 
During the period of our stay in the interior we had arranged, 
through the kind assistance of Mr. Carstensen, to send two natives 
to collect plants near Agadir, about 80 miles south of Mogador, near 
to Cape Guer, where the Great Atlas range finally subsides into 
the Atlantic Ocean. The result, which seemed to show that the 
character of the vegetation does not vary much along this part of 
the coast, yet sufficed to prove that with due perseverance some- 
thing might be accomplisbed towards extending our knowledge of 
the Marocco flora through native collectors. 
M. Cosson, having succeeded in securing the active assistance 
of the late M. Beaumier, French Consul at Mogador, and sparing 
on his own side neither trouble nor expense to effect his object, 
has caused two native collectors to travel into the interior for 
several successive seasons. One of these, a very intelligent Jew, 
a native of Akka, a place on the southern side of the Great Atlas 
between the rivers Sous and Noun, has been chiefly employed in 
the region, utterly inaccessible to European travellers, between the 
oasis of Akka and the neighbourhood of the Atlantic coast. The 
other, a Schleuh by birth, and a native of the mountains, has been 
mainly engaged in making collections in a district nearly adjoining 
the portion of the Great Atlas which we were able to explore. 
The collections first sent home were in indifferent condition, and 
the specimens incomplete ; but M. Cosson’s perseverance over- 
came all difficulties, and the collections lately received would do 
credit to a professed naturalist. 
When I consulted my excellent friend M. Cosson on the sub- 
ject of the present publication, he was good enough to suggest 
that we should jointly bring out a work which might bear to the
