Jepson Flora Project: Jepson Interchange for California Floristics    
Plantago heterophylla Nutt.
Initial Editorial Analysis 31 Mar 2005
Source of Report for California Munz, P.A. in collaboration with D. D. Keck. 1968, as cited in Kartesz & Meacham
Initial Editorial Comments indicated as adventive in California in Rosatti (JAA 65: 544. 1984), citing Pilger; said to be "nearly indistinguishable" from Plantago pusilla by Rosatti (JAA 65:543. 1984); indicated for California in Abrams & Ferris, Illustrated Flora of the Pacific States; in no way mentioned in The Jepson Manual [Ed. 1]
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 $ 8 Feb 2002, from Margriet Wetherwax see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Plantago heterophylla listed as misapplied under Plantago elongata in original The Jepson Manual [Ed. 1] treatment, and that in Munz Supplement it was indicated for California but then said to occur only in e US. [Plantago heterophylla in no way mentioned in The Jepson Manual [Ed. 1], but is indicated as misapplied in Dempster's original ms for The Jepson Manual [Ed. 1]. The account in Munz Supplement is contradictory, in that it is stated that, according to Bassett (1966), it occurs in CA, but then it is stated that it occurs only in e US. According to Rosatti (JAA 65:543. 1984), Pilger (Das Pflanzenreich IV. 269 (Heft 102): 1-466. 1937) indicated that it is evidently native to Argentina and Paraguay and adventive in CA, while Bassett (1966) reported it is adventive in ne US.]
Correspondence 2 31 Mar 2005, from Editor of this Index see Comment 2
Editorial Comments 2 Bassett (1966) indicated a distribution for Plantago heterophylla in se US, from OK and TX to the eastern coastline, with introductions as far n as NY. The evidently mistaken idea that it occurs in California might have resulted from two items in Bassett (1966): first, one of the cited specimens (p. 475), collected in Alabama, is indicated as being housed in UC; second, in discussing chromosome numbers, Bassett wrote that Moore (1962, Madrono 16:266-268) "reported a somatic chromosome number of 2n = 22 for P. heterophylla from Santa Rosa Island, California. I was not able to obtain the voucher specimen from this reported count, but as P. heterophylla has not been found in California, I would expect the plant in question to be P. bigelovii subsp. californica."
Correspondence 3 3 Jun 2009 e-mail from Ellen Dean see Comment 3
Editorial Comments 3 Correspondence 3 indicates that 2 of the accessions in CCH (as of 4 Jun 2009) from UCD identified as Plantago heterophylla, UCD35488 and UCD36590, are not assignable to this species, at least on the basis of seed number per fr and seed size, the 2 key characters used to separate it from Plantago elongata and Plantago pusilla in the new key to species of Plantago for The Jepson Manual [Ed. 2] ("a few tan immature seeds per ovary" for UCD35488, and "4 black, mature, pitted seeds per ovary that are each ca. 1.5 mm long" for UCD36590). Correspondence 3 also indicates that there were a total of 9 specimens in UCD identified as Plantago heterophylla, but that all nine have now been annotated by Dean as Plantago elongata. [Despite the existence of 2 additional accessions (UCR16545, RSA643235) in CCH as Plantago heterophylla, both from qualifying conditions, it seems most reasonable at this time to continue to treat this species as not occurring in CA. A note that it has been reported but not documented as alien, possibly naturalized in California (and a note online indicating roughly how to identify it) is to appear in the treatment of Plantago for The Jepson Manual [Ed. 2].]
