Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 Treatment and author notes submitted for The Jepson Manual [Ed. 2] see Comment 1
Editorial Comments 1 Correspondence 1 evidently does not address Linum trigynum L..
Correspondence 2 26 and 31 Aug 2013 e-mails from Peter Warner, including previous e-mails from Warner and Joshua R. McDill, author of Linaceae for The Jepson Manual [Ed. 2] see Comment 2
Editorial Comments 2 Correspondence 2 indicates: that Warner has collected plants he identified as Linum trigynum from a population at Jenner Headlands in Sonoma County, in a grassland of annual and perennial, native and alien taxa, that he estimates to be in excess of 1 million individuals; that Warner also reports seeing (but evidently not collecting) this taxon at Fort Ross, in upland pastures, as well as being aware of its having been observed at Sea Ranch previously; that Warner believes its persistence along the Sonoma County coast is "hardly waif-like" [i.e., he believes is it naturalized there]; and that McDill had originally included this species in the treatment he submitted for The Jepson Manual [Ed. 2], albeit as a waif [which meant it should have been included in the key to members of Linum in The Jepson Manual [Ed. 2], but fully treated online only, in the Jepson eFlora], even though he never was able to see any collections of the taxon from California.
