522 SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. SO 



Series MICROCARPAE 



According to Schumann, characterized by the small fruit. The 

 two species which he refers here probably do not belong to the 

 same series. 



OPUNTIA STRIGIL Engelm. 



Opuntia strigil Engelm. Proc. Am. Acad. 3:290. 1856. 



Type locality: Between the Pecos and El Paso, Texas. 



Distribution: Texas. 



Illustration: Cact. Mex. Bound, pi. 67. 



OPUNTIA MICRO CARP A Schum. 



Opuntia microcarpa Schum. Gesamtb. Kakteen 714. 1899. 



Type locality: Cul de Sac, Haiti. 



Distribution : Known only from the type locality. 



Not seen by us. Probably not at all related to O. strigil. 



This name is a homonym of O. microcarpa Engelm. 1 If the 

 species proves to be a good one a new name must be proposed. 

 Opuntia macracantha Griseb. 2 from maritime situations in Cuba, was 

 supposed by Professor Schumann to be of this relationship.
