Bermudas. — Indigenous ? Common — Jones. 



West Indies and Tropical America. 



This species is also cultivated, and Engelmann (Synop. Cact. U.S. in Proc. Am. Acad., 

 iii. reprint, p. 34) states that specimens gathered on the coast of South Carolina ("pro- 

 bably introduced ") may belong to this species, 



Opuntia vulgaris, Mill.

Bermudas. — Indigenous ? Without locality — Lane. 



This species, according to Engelmann, ranges from the south-eastern coast of Massa- 

 chusetts to Georgia and Florida. 



As is set forth more fully in the introduction, one or more species of "prickly 

 pear" were found in abundance by the first Englishmen who visited the islands; but 

 we have seen no specimen of any species from the Bermudas, hence we can only give 

 the names cited by the different writers. From their continental and West Indian dis- 

 tribution, there is no reason why all four of the species enumerated should not be wild 

 in the Bermudas ; yet as great confusion prevails in the names of Cactacece, it may be that 

 there are only two, or at most three, species concerned. In his list, Rein includes only 

 Opuntia pes-corvi and Opuntia Jicus-indica, while in his description of the vegetation 

 of the islands he mentions Opuntia tuna, in conjunction with the former, as one of the 

 two species occurring in a wild state. Further, Opuntia tuna is included on the authority 

 of Jones alone.
