Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by Robert F. Thorne, C. Barre Hellquist, & Robert R. Haynes see Comment 1
Editorial Comments 1 Correspondence 1 indicates that material on which occurrences in California of Limnobium laevigatum (Humb. & Bonpl. ex Willd.) Heine have been based belongs instead to Limnobium spongia (Bosc) Rich. ex Steud. [although Limnobium spongia (Bosc) Rich. ex Steud. is not indicated for California in Flora North America].
Correspondence 2 16 Dec 2011 e-mail from Bruce G. Baldwin, including forwarded e-mails from Robert R. Haynes and Margriet Wetherwax see Comment 2
Editorial Comments 2 Correspondence 2 indicates that, according to Dean Kelch (pers. comm. to Baldwin), Fred Hrusa has determined that relevant California material belongs to Limnobium laevigatum (Humb. & Bonpl. ex Willd.) Heine and not Limnobium spongia (Bosc) Rich. ex Steud., and that the latter name has therefore been misapplied in California [there is one record in CCH labeled Limnobium spongia, but it is from material grown in a greenhouse in CA], a situation opposite that presented in The Jepson Manual [Ed. 2].
