Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by Mihai Costea, and 14 Jul 2006 e-mail from Fred Hrusa to Costea see Comment 1
Editorial Comments 1 Correspondence 1 indicates that, according to Fred Hrusa, Cuscuta japonica (identity confirmed by Mihai Costea) is being found "all over the state now", "would appear to be spreading vegetatively", and "rarely forms flowers".
Correspondence 2 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by Mihai Costea, and 21 Nov 2006 e-mail from Fred Hrusa to Costea see Comment 2
Editorial Comments 2 Correspondence 2 indicates that, according to Fred Hrusa, specimens of Cuscuta japonica (identity confirmed by Mihai Costea) from California "are so far all urban or close by", and that, according to Mihai Costea, the plants may be spread by birds through stem fragments and therefore could be expected in wildlands, and that they belong to Cuscuta japonica var. formosana (although Cuscuta japonica var. japonica may occur in California as well).
