122 ERYTHEA. 



Opuntia prolifera Eugelm. Am. Jour. Sci., ser. 2, xiv, 338 

 (^1852). Southward some distance into the peninsula — how far is 

 not yet known. The plant from Guadalupe is doubtfully identified. 



Opuntia cholla Web. 1. c. 6 is the 0. prolifera of Mr. Bran- 

 degee's lists as to the plant of the southern part of the peninsula. 

 To this may belong the specimen from Magdalena Island referred 

 by Prof. Coulter to O.fulgida. 



Opuntia molesta Braudg. Proc. Cal. Acad., ser. 2, ii, 164. To 

 this may belong 0. Calmalliana Coult. 1. c. 453, and 0. clavellina 

 Engelm. in Coult. 1. c. 444 — closely related species. 



Opuntia ciribe Engelm. in Coult. 1. c. 445, "from Comoudu 

 and Loreto northward beyond Rosario." Gabb's fragment appears 

 to be lost, but in our herbarium is a sheet containing two spec- 

 imens, one from Purisima and one from Comondu, which answer to 

 the description. The sheet has the name Opuntia Bigelovli Eugelm. 

 written upon it between the labels and attested by the initials J. M. C. 

 It is also growing in our garden, collected by Captain Porter some- 

 where in the peninsula. 



Opuntia serpentina Engelm. 1. c. . Northern part of the 

 peninsula. 0. serpentina of Mr. Brandegee's list, from Magdalena 

 Bay, is certainly not that species. Cereus (?) Californicus Nutt. in 

 T. & G. Fl. N. Am. i, 555, 1840, is the oldest name of this species, 

 though Nuttall appears to have described the plant of 0. prolifera 

 and the flower of 0. serpentina. 



Opuntia alcahes Web. 1. c. 6 (1895). This species and 0. 

 cholla are the common cylindric Opuntias of the Cape Region. 

 0. alcahes is very near, if not identical with 0. echinocarpa nuda 

 Coult. 1. c. 446. 



Opuntia fulgida Engelm. Syn. Cact. 806, as to Mr. Brandegee's 

 specimen from Calamajuet, has yellow flowers with only a slight 

 reddish tinge on the outside^ as is common in many of the yellow- 

 flowered species. 



Opuntia ramosissima Engelm. Am. Jour. Sci., ser. 2, xiv, 339 

 (1852). 0. tessellata Engelm. Syn. Cact. 309 (1856). This has 

 not been found on the peninsula, so far as I know, but it occurs on 

 San Benito Island.
