INTRODUCED PLANTS OF AFRICA 



345 



Vitis vinifera, the grape ; the fruit produced at Zanzibar, was said to 



be of inferior quality. 

 Amijgdalus Persica, the peach. A single tree, which Avas " brought 



from America," seemed to be in a thriving condition ; but it had 



not produced fruit. 

 Jambosa Malaccensis, was seen growing on the Imaum's plantation. 

 Caryophyllus aromaticiis, cloves ; are now extensively cultivated, and 



form an important article of export from Zanzibar. 

 Lactuca sativa, lettuce, according to the traders, had been introduced 



from America ; but I did not meet with the plant. 

 Durio zibethinus, several trees, were seen on the Imaum's plantation. 

 Solanum tuberosum. Potatoes, are well known at Zanzibar ; and are 



principally imported from India; but I once saw the plant under 



cultivation. 



Myristica moschata, the nutmeg : trees, in a thriving condition, were 

 seen on the Imaum's plantation. 



Ficus carica, the fig. A single tree, having unripe fruit and unu- 

 sually large leaves, was seen in a garden at Zanzibar. 



In conclusion, it should be observed; That domestic animals and 

 plants of African origin, are not altogether wanting on the island 

 of Zanzibar. Such as : 

 The domesticated guinea fowl, abounding. 



Adanso7iia, perhaps, originally introduced; although young stocks 

 were seen, that had been spontaneously disseminated. The shell 

 of the fruit, is used by the Soahili as a substitute for water-buckets. 



Erythrina. A large and magnificent tree, perhaps of African origin, 

 growing on a plantation on the island of Zanzibar. 



Momordica balsamina, the fruit, brought to the market at Zanzibar. 

 This plant also, is possibly of African origin. 



Jatropha curcas, naturalized around houses at Zanzibar : as likewise 

 at Bombay. — I first met with the Jatropha curcas at the Cape Verd 

 Islands; where it had the appearance of being indigenous. And I 

 observed a corresponding species, truly wild, in Yemen.
