Information from the Index of California Plant Names (ICPN)
Misapplications Cited in The Jepson Manual Hemizonia congesta DC. subsp. congesta
Initial Editorial Analysis Nov 1 2001
Source of Report for California The Jepson Manual [Ed. 1]
Initial Editorial Comments according to Baldwin (Systematic Botany 26: 184-194, 2001), the types of Hemizonia congesta subsp. congesta and Hemizonia congesta subsp. leucocephala have been found to belong to the same taxon, with the name Hemizonia congesta subsp. congesta having priority, so that Hemizonia congesta subsp. leucocephala is a later synonym of Hemizonia congesta subsp. congesta
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 1 Dec 2004 e-mail from Misa Ward see Comment 1
Editorial Comments 1 Correspondence appended verbatim is pertinent to The Jepson Manual [Ed. 2] account: "Move to List 1B? Precise location, rarity, and endangerment information needed. Intergrades with subsp. congesta; dried plants may be indistinguishable. Many herbarium collections are misidentified. Threatened by agriculture and urbanization. See Bulletin of the Torrey Botanical Club 110:15 (1983) for original description, and Phytologia 73(3):259-260 (1992) for revised nomenclature."
