CH. XIII. A NEW CACTOID EUPHOEBIA. 337 



rounds the western extremity of Anti-Atlas, through a hilly 

 and populous country, which appears to be safe enough for 

 any but Christian travellers. 



Among other articles exported from ]Mogador is the 

 brown gum arable of commerce, which comes chiefly from 

 Demnet, and elsewhere on the skirts of the Atlas east of 

 Marocco. If native testimony is to be credited, the Acacia 

 producing this gum is not different from that which we 

 saw growing abundantly in Haha and elsewhere through 

 the hilly country,' though we did not hear of any gum 

 being exported from the western provinces. It seems un- 

 likely that this plant, named by Wildenow Acacia gurw- 

 nnifera, should be the only one of a group of allied species 

 extending across Northern Africa that produces no gum. 

 We were interested in finding that the parcel shown to 

 us, sent for export from Mogador, was packed in the dry 

 stems and leaves of a Geratophyllum, a genus of aquatic 

 plants not hitherto seen in Marocco. 



During the afternoon the two natives who were de- 

 spatched two days before returned safely from Haha, 

 driving before them a donkey laden with the Agadir 

 Euphorbia. Hooker's suspicion was at once verified. The 

 plant of the coast region is quite different from the gum- 

 producing species of the inland region, but in appearance it 

 comes near the East Indian species, JE. offLcinarwm of Lin- 

 naeus. Under the name E. Beaumieriana, the coast plant, 

 which has yet not been collected in flower or fruit, along 

 with E. resinifera from Demnet, and another new species 

 brought by a native collector from the southern borders of 

 Sous, has been careftilly described by our friend M. Cosson. 

 In the course of the evening we went by invitation to 

 a Jewish wedding, which was celebrated in the house of 

 one of the chief Israelite families in the town. The pro- 

 ceedings were quite in accordance with the descriptions 

 given by other travellers in Marocco. The bride, who sat 

 cross-legged, arrayed in gorgeous attire, had regular fea-
