Talk:Pelecyphora vivipara

not Coryphantha clorantha
On 16 June 2014‎ FloraWilde moved Escobaria vivipara to Coryphantha clorantha citing a wildflower book, and indicating that the reference to Jebson's Manual was vague, even though the express link was given in references replicated here. The name Coryphantha clorantha does not exist in the IPNI database. No new scientific papers have reclassified Escobaria vivipara. Scientific papers such as, continue to use the name Escobaria vivipara. See Google Scholar for more examples. On this basis I have reverted the edits made by FloraWilde as the source cited is not a reliable source. However, I am open to a discussion based upon scientific papers. --Bejnar (talk) 05:47, 17 June 2014 (UTC)

Coryphantha clorantha does not seem to occur in any publication. Perhaps editor FloraWilde meant Coryphantha chlorantha ((Britton & Rose, 1923), aka desert pin-cushion. In, the author says:
 * Many California botanists and cactus enthusiasts know our native pincushion cacti as varieties of Escobaria vivipara, as treated in The Jepson Manual (Hickman 1993) and The Jepson Desert Manual (Baldwin et al. 2002). The International Cactaceae Systematics Group recognizes Escobaria as a valid genus, and Edward Anderson in The Cactus Family (2001) treats our taxa as distinct species of Escobaria. However, the Flora of North America (Zimmerman and Parfitt 2003) does not recognize Escobaria as a separate genus, and treats the three varieties of E. vivipara as species of Coryphantha. Since the soon to be published second edition of The Jepson Manual will follow this newer treatment (B. Parfitt, personal communication), now is a good time to get to know these small, benign, and beautiful cacti.

The new edition The Jepson manual: vascular plants of California (ISBN 9780520253124) was published in 2012, unfortunately, I do not have immediate access to a copy. Ingram goes on to say that Coryphantha chlorantha is equivalent to Coryphantha vivipara var.  deserti, but Ingram believes that it is a separate species from the rest of Coryphantha vivipara. If the new (2012) Jepson Manual accepts Ingram's reasoning, then this article would become Coryphantha vivipara, and a new article would be needed for Coryphantha chlorantha. Escobaria vivipara var. deserti was originally named Mammillaria chlorantha by George Engelmann. --Bejnar (talk) 06:53, 17 June 2014 (UTC)


 * The 2012 Jepson (p.580) has three varieties of Escobaria vivipara being reclassified as three species of Coryphantha.


 * Escobaria vivipara (Nutt.) Buxb. var. alversonii (J.M. Coult.) D.R. Hunt, is reclassified as species ''Coyphantha alversonii (J.M. Coult.) Orcutt (p. 583) (common name - foxtail cactus)
 * Escobaria vivipara var. desertii (Engelm.) D.R. Hunt, is reclassified as species - Coryphantha chlorantha (Englm. Britton & Rose (common name - desert pincushion)
 * Escobaria vivipara var. rosea (Clokey) D.R. Hunt, is reclassified as species - Coryphantha vivipara (Nutt.) Britton & Rose var. rosea (Clokey) L.D. Benson (p. 583) (common name - viviparous foxtail cactus). Escobaria is not listed as a genus in the new Jepson, but Jepson only covers California. I will write up a Coryphantha genus article, and three new species articles, from the descriptions in Jepson, and unless there is objection. FloraWilde (talk) 16:43, 15 May 2015 (UTC)
 * No objection here. I do like reliable sources, and that seems to be in accord with Zimmerman. --Bejnar (talk) 14:31, 16 May 2015 (UTC)
 * Unfortunately, FloraWilde was blocked indefinitely on 1 July 2015 for abusing multiple accounts, prior to completing this task. --Bejnar (talk) 02:33, 12 October 2015 (UTC)
