Initial Editorial Comments in no way mentioned in The Jepson Manual [Ed. 1]; indicated for southern tier of states in Kartesz & Meacham; according to Source c, status uncertain, although conditions of cited occurrences (e.g., in mung bean crop, in Botanic Garden) seem not to qualify for inclusion in the flora according to criteria employed by Jepson Flora Project (14 Feb 2003).
