CHAPTER XXIV. 



INTRODUCED PLANTS OF SOUTHERN ARABIA. 



If the Interior mountains of Yemen be excepted, agriculture, is 

 very sparingly carried on in Arabia; and only, by means of irrigation 

 from wells. In the details of this process, maintained with great 

 labour in the midst of a Desert, weeds, which in other countries 

 accompany the footsteps of man, rarely obtain foothold. 

 Rhapliaims sativus. Radishes, were seen in market, both at Mocha, 



and at Muscat. 



Gossypium herbaceiim, a few stocks, observed growing in a court-yard 

 in the outskirts of Mocha. 



Hibiscus esculentus, the fruit, abundant in the market at Mocha. 



Thespesia populnea, a single tree, planted in a court-yard, in the out- 

 skirts of Mocha. The leaves were in demand, as an external ap- 

 plication to wounds. 



Citrus Medica, the Sweet Lemon, cultivated in the environs of Mus- 

 cat; and I have never seen it elsewhere. It is an insipid fruit. 



Citrus limonum, the lime, was seen at Muscat. 



Citrus, the lemon ; the fruit, seen in the market at Mocha. 



Citrus aurantium. I did not meet with oranges ; but I was informed, 

 that they are sometimes imported into Mocha, fiom Egypt. 



Vitis vinifera. Grapes of excellent quality, were unexpectedly met 

 with, both at Aden and at Muscat. 



Zizijphus, a species of lote-tree, planted in gardens at Muscat. 



Pistacia vera. Pistacliio nuts, were said to be sometimes brought to 

 the market at Mocha. 



Mcmgifera Indica. The mangoes brought to the market at Mocha, 

 are small, and of inferior quality. 



Pai'kinsonia aculeata, planted for ornament, in the vicinity of Mocha. 

 According to the Arabs, the tree was brought from India.
