Curto 635, 25 Apr 1990, Cuesta Pass, San Luis Obispo Co.); indicated for CA, OR, NV, UT, AZ in Kartesz & Meacham (Kartesz & Meacham citation = The Jepson Manual [Ed. 1]); in no way mentioned in Munz, Munz Supplement, The Jepson Manual [Ed. 1] (despite Kartesz & Meacham citation). | |||||

| Correspondence and Comments Subsequent to Initial Analysis | ||||||
| Correspondence 1 | 14 Nov 2005 e-mail from Jeff Greenhouse see Comment 1 | |||||
| Editorial Comments 1 | Correspondence 1 indicates that Bromus "Berterianus" was the original spelling used by Luigi (Aloysius) Colla (Colla in Authors of Plant Names) when he published the name in Memorie della Reale Accademia delle Scienze di Torino 39: 25, t. 58. 1836; that Colla indicated in the title of his article that the plants described were recently discovered in Chile by M. D. Bertero; that the epithet termination used by Colla indicates his intention to create an adjectival epithet, the spelling of which is required by ICBN 2000 (St. Louis Code) Art. 60.11 and Rec. 60C.1(c) to be "berteroanus"; and that "berteroanus" is the spelling in the TROPICOS and International Plant Names Index databases, as well as in the treatment submitted for The Jepson Manual [Ed. 2] by J. M. Saarela and P. M. Peterson. [Therefore, spelling of epithet corrected to "berteroanus", from "berterianus" previously in this Index, 14 Nov 2005.] | |||||
| Correspondence 2 | 17 Apr 2008 e-mail from David J. Keil see Comment 2 | |||||
| Editorial Comments 2 | Correspondence 2 indicates that Dave Keil again has collected Bromus berteroanus Colla from southern San Luis Obispo County, in a wildlands habitat (grassland understory of foothill woodland), that there are [presumably, at Cal Poly] several additional specimens from scattered localities in the county, and that the sp. is mapped from various other areas of California in Flora North America. | |||||
| Correspondence 3 | 8 Apr 2012 e-mail from David J. Keil see Comment 3 | |||||
| Editorial Comments 3 | Correspondence 3 indicates that, according to Keil, Bromus berteroanus Colla is native to South America and naturalized, not native, in CA. | |||||
| Correspondence 4 | 10 Apr 2012 e-mail from Jeff Saarela, senior author of Bromus for The Jepson Manual [Ed. 2] see Comment 4 | |||||
| Editorial Comments 4 | Correspondence 4 indicates that Jeff Saarela, senior author of Bromus for The Jepson Manual [Ed. 2], agrees to changing the status of Bromus berteroanus Colla to naturalized in CA, from native as indicated by font in The Jepson Manual [Ed. 2]. | |||||
| Correspondence 5 | 5 Apr 2013 e-mail from Dave Keil, including forwarded emails from Fred Roberts, Andrew G. Sanders, and Tom Chester see Comment 5 | |||||
| Editorial Comments 5 | Correspondence 5 includes circumstantial evidence for and against the idea that Bromus berteroanus Colla is not native in CA. That it is not native is suggested by the fact the earlier records of the species in CCH are all from coastal areas where human introduction would be most likely [but see below], and that collections of undoubtedly native grasses in CCH tend to appear at least 20 years earlier than those of Bromus berteroanus and some but not all of the undoubtedly not native taxa that were collected from areas of California that were botanized early [Keil]. That it is native is supported by the idea that in most habitats Bromus berteroanus behaves more like a native [e.g., not particularly aggressive], that on the "coastal slope" of s California the species "collapsed" after the arrival of weedy grass species (in the Riverside area, with the arrival of Bromus rubens in particular) [Sanders], and that there are, despite the statement above to the contrary, early collections of the species from non-coastal areas in California (1 CCH record from the Sierra Nevada in 1864: Brewer 2800, GH); 1 Smithsonian record from the Panamint Mtns. in 1891: Coville & Funston 522) [Roberts]. The last email in the thread suggested that molecular evidence would be needed to resolve this matter, in part because the circumstantial evidence is equivocal. | |||||
