Plantago psyllium L. nom. rej.

Information from the Index of California Plant Names (ICPN)
Initial Editorial Analysis 25 Mar 2005
Source of Report for California The Jepson Manual [Ed. 1], as cited in Kartesz & Meacham
Initial Editorial Comments in no way mentioned in The Jepson Manual [Ed. 1] (despite Kartesz & Meacham citation); indicated for California to BC and ne NA in Kartesz & Meacham; Plantago indica said to be "reported from...many parts of the state, as it is often a constituent of commercial bird-seed, poultry-feed, etc. Native of Old World...often identified as P. psillium L....", in Munz; Plantago psyllium itself, somewhat inaccurately, said to be "known from many parts of California because it is often a constituent of commercial bird-seed (Munz)" in Rosatti (JAA 65:547. 1984)
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 25 Mar 2005, from Editor of this Index see Comment 1
Editorial Comments 1 Most treatments, dating from Fl. Europaea (1976, Vol. 4, p.43) and possibly earlier, treat Plantago psyllium L. 1753, Plantago indica L. 1759, and Plantago arenaria Waldst. & Kit. 1801 as conspecific, under Plantago arenaria. According to Parnell (2003, An Account of the Plantaginaceae in Thailand, Thai. For. Bull. Bot. 31:53-64): Rahn's work on phylogeny of the group (1996. A phylogenetic study of the Plantaginaceae. Bot. J. Linn. Soc. 120: 145-198) remains the most up-to-date summary; Panigrahi (1975, Kew Bull. 30: 669-673) showed that the name Plantago indica was coined by Linnaeus in 1759 as a new name for a species he had already described in 1753 as Plantago psillium, rendering Plantago indica superfluous and invalid; Verdcourt (1969, Kew Bull. 23: 509; 1971, in Milne Redhead & Polhill, eds., Flora of Tropical East Africa) has shown that Plantago psillium is a nomen ambiguum and therefore cannot [should not?] be used, a view also held by Rahn (1996); the first available, valid epithet therefore is that of Waldstein & Kitaibel (1801, Pl. Rari Hung. 1: t. 51); under current rules, a proposal should be submitted to reject Plantago psillium, as until this is done it remains the correct name for this taxon [or, under Art. 9.7, an epitype for Plantago psillium should be designated]; and "psillium" is a taxonomically confusing epithet due to its use in Asian pharmaceutical preparations. [Despite the foregoing, Parnell and most other current workers use Plantago arenaria for this species, a practice that will be adopted in this Index at least until the matter is formally resolved to the contrary. Whatever the status of the three names involved, there is general acceptance at present that only one taxon is represented by them.]
Correspondence 2 3 Aug 2015 e-mail from Dave Keil see Comment 2
Editorial Comments 2 Correspondence 2 indicates that a proposal (Taxon 55(1):235-236. 2006) to reject the name Plantago psyllium L. has been approved (Taxon 60(4):1211-1214. 2011). [Therefore, Plantago psyllium L. nom. ambig., previously in this Index, changed to Plantago psyllium L. nom. rej., 3 Aug 2015.]
