BRITTOI^-^D ROSE] OPUNTIOIDEAE OF NORTH AMERICA 519 



OPUNTIA PYCNANTHA Engelm. 



Opuntia pycnantha Engelm. ; Coult. Contr. Nat. Herb. 3:423. 1806. 



Type locality : Magdalena Bay, Lower California. 

 Distribution : Lower California. 



OPUNTIA PYCNANTHA MARGARITANA Coult. 



Opuntia pycnantha margaritana Coult. Contr. Nat. Herb. 3:424. 1896. 



Type locality : Santa Margarita Island, Lower California. 



Distribution : Lower California. 



An examination of the material in the Brandegee herbarium, both 

 of pycnantha and its variety as well as of O. comonduensis, showed 

 that they all have pubescent joints and should therefore be trans- 

 ferred to the series Pubescentes. 



OPUNTIA COMONDUENSIS (Coult.) Britton & Rose 



Opuntia angustata comonduensis Coult. Contr. Nat. Herb. 3:425. 1896. 



Type locality : Comondu, Lower California. 



Distribution : Southern Lower California. 



As pointed out by Mrs. K. Brandegee, this plant has nothing to 

 do with true O. angustata, and, as it appears not to have been pub- 

 lished as a species heretofore, we now raise Coulter's variety to 

 specific rank. Through the kindness of Mr. Hall and Mr. Brandegee, 

 we have been permitted to examine the type now in the Brandegee 

 herbarium at the University of California. Coulter has labeled two 

 sheets as such, both collected by Mr. Brandegee at Comondu in 1889. 



One of these has hairy joints and the other is glabrous. The 

 former is selected as the type.

OPUNTIA PILIFERA Weber 



Opuntia pilifera Weber in Bois, Diet. Hort. 894. 1898.

OPUNTIA CRINIFERA Salm-Dyck 



Opuntia crinifera Salm-Dyck; Pfeiff. Enum. Cact. 157. 1837.
