Bixa orellana, the Arnotto, is now cultivated at the Hawaiian Islands; 

 and, according to Mr. Rich, at Tongataboo. The Arnotto, was also 

 seen in the East Indies, at Zanzibar, at Rio Janeiro, and in Peru. 



Tribulus, a species, perhaps from Mexico, growing in arid situations, 

 in the vicinity of the Hawaiian towns. 



Melia azederach, said to have been " brought by the Vincennes on a 

 former cruise, from the East Indies to the Hawaiian Islands." The 

 tree was also seen at Taheiti. 



Citrus aurantium, the orange, is now cultivated at the Hawaiian 

 Islands, at Taheiti, and at Samoa; and the fruit was seen in one 

 instance, at the Feejee Islands. 



Citrus, the lemon, is now cultivated at Taheiti and at Samoa. And 

 the rough-skinned variety, is so abundant at the Feejee Islands, 

 that I have had doubts as to its alleged European introduction; 

 the question, may probably be decided by the etymology of the 

 name given to the plant by the natives. 



Citrus limonum, the lime, was seen cultivated at the Hawaiian Isl- 

 ands, at Taheiti, and at Tongataboo ; and a single tree, was re- 

 ported to exist at Samoa, the time and mode of its introduction 

 being uncertain. 



Mangifera Indica, the mango, planted at the Hawaiian Islands ; but 

 at the time of our visit, the trees were not full grown. 



Cassia occidentalism naturalized at the Hawaiian Islands, at Taheiti, 

 and at Samoa ; and it was seen, regularly planted, at Tongataboo. 



Cassia tora, naturalized at Taheiti. 



Cassia scandens, cultivated at Oahu, in the gardens of the resident 

 Whites. 



Vachellia, apparently the Chilian species, introduced into Taheiti. 

 Indigofera, a shrubby species, naturalized at the Hawaiian Islands and 



at Taheiti ; and planted by the missionaries at Samoa. The same 



species, perhaps, was seen in Peru, and in the East Indies. 

 Inga Sinemariensis ? The pacai bean of Peru ; some stocks were 



seen growing at Taheiti. 

 Cajanus Indicus, cultivated at the Hawaiian Islands. And also, in 



the East Indies, and at Zanzibar. 

 Desmodium, a low herbaceous species, said to have been brought from 



the Mexican coast, is naturalized in the environs of Honolulu. 

 Crotalaria, a species, abundantly naturalized at Taheiti. 

 Poinciana, already noticed, as apparently of aboriginal introduction in 



the central groups. — But at the Hawaiian Islands, the plant was
