Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 5 Jun 2003 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Dave Keil (7 May 2003 e-mail to M. Wetherwax) reports "Ceanothus griseus (The Jepson Manual [Ed. 1] p. 936) grows in chaparral near Coon Creek in the San Luis Range", so that chaparral is to be added to the habitats listed in The Jepson Manual [Ed. 1].
Correspondence 2 5 Jun 2003 e-mail from Jeff Greenhouse see Comment 2
Editorial Comments 2 Correspondence 2 indicates that this name was based on Ceanothus thyrsiflorus Eschsch. var. griseus Trel. published in Gray and Robinson, Synoptical flora of north america, 1(1):415--416 (1897); although the work was edited by Robinson, Trelease wrote the account for Rhamnaceae, including the protologue in question, a conclusion shared by D. Wilken (The Jepson Manual [Ed. 2] co-author), in a 3 Jun 2003 e-mail. [Therefore, the author citation is correct as indicated, Ceanothus griseus (Trel.) McMinn]
Correspondence 3 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by Dieter H. Wilken see Comment 3
Editorial Comments 3 Correspondence 3 indicates that for The Jepson Manual [Ed. 2] Ceanothus griseus (Trel.) McMinn is to be treated as a synonym of Ceanothus thyrsiflorus Eschsch. var. griseus Trel..
