Jepson Flora Project: Jepson Interchange for California Floristics    
Opuntia curvispina Griffiths
CACTACEAE
Initial Editorial Analysis 3 Dec 2019
Source of Report for California The Jepson Manual [Ed. 1], as minor variant of Opuntia chlorotica
Initial Editorial Comments stabilized hybrid between Opuntia chlorotica and Opuntia phaeacantha according to The Jepson Manual [Ed. 1]; possibly to be replaced with hybrid form of name, Opuntia X curvispina
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 18 Feb 2005 Interchange Feedback from Bruce D. Parfitt see Comment 1
Editorial Comments 1 Correspondence 1 indicates that the spelling of this name has been corrected in Flora of North America to Opuntia àcurvispina (instead of curvo...).---an orthographic correction. [Therefore, spelling of epithet corrected to Opuntia curvispina Griffiths, from Opuntia curvospina Griffiths previously in this Index, 22 Feb 2005.]
Correspondence 2 Treatment and author notes submitted for The Jepson Manual [Ed. 2] see Comment 2
Editorial Comments 2 Correspondence 2 indicates that for The Jepson Manual [Ed. 2] Opuntia curvispina Griffiths is to be treated as a synonym of Opuntia X curvispina Griffiths, which is to be treated as an unresolved variant, of Opuntia chlorotica Engelm. & J.M. Bigelow, for which the matter of taxonomic recognition or not requires further study, and therefore remains tentative.
Correspondence 3 7 Sep 2016 email from Marc Baker see Comment 3
Editorial Comments 3 Correspondence 3 indicates that, according to Marc Baker, author of Opuntia in The Jepson Manual [Ed. 2], this taxon is well-established, "much more than simply spontaneous", so that it is more appropriate to use the non-hybrid form of the name.
Correspondence 4 16 Feb 2018 email from Marc Baker see Comment 4
Editorial Comments 4 Correspondence 4 indicates that, according to Marc Baker, author of Opuntia in The Jepson Manual [Ed. 2], the general consensus now is that Opuntia curvispina Griffiths should be regarded as a good species, not as a nothospecies, although it may or may not be of hybrid origin, and that he is ready to "write up a species description and include the species in the key".
