Brief Summary of Changes in Revision 1
Arida (Asteraceae): Arida changed to Leucosyris, which has nomenclatural priority; Arida changed to Leucosyris in keys to genera of Asteraceae: in key to genera of Asteraceae, Group 6, A. carnosa changed to L. carnosa at key lead 15 and the leads reversed for alphabetical order (p. 217 in TJM2); in key to genera of Asteraceae, Group 14, A. arizonica changed to L. arida at key lead 26, and the leads reversed for alphabetical order (p. 227 in TJM2). Note under Machaeranthera changed to: Other taxa in TJM (1993) moved to Arida in TJM2 (2012); taxa included in Arida in TJM2 (2012) moved to Leucosyris. Arida names included in illustrations on page 247 in TJM2 to be changed to follow revised taxonomy.
Asclepias (Apocynaceae): A. linaria deleted (previous inclusion based on faulty locality data), with removal from key to members of Asclepias as well.
Atriplex (Chenopodiaceae): Three taxa moved to new genera Extriplex and Stutzia, the rest retained in Atriplex, with incorporation of new genera into key to genera of Chenopodiaceae.
Cyatheaceae: Sphaeropteris cooperi added to flora as naturalized, requiring treatment of Cyatheaceae as well as its placement in Family Key, Group 3.
Dodecatheon (Primulaceae): Dodecatheon transferred to Primula, expanding the latter in California from one to twelve taxa.
Euphorbiaceae: Chamaesyce transferred to Euphorbia, with unification under the latter in key to genera of Euphorbiaceae, and incorporation into one key of taxa treated in keys to members of Chamaesyce and Euphorbia in TJM2, into one key; the revision for Supplement I also includes addition of a species new to science, E. jaegeri, as well as partial treatment of taxa shown to occur as waifs in the state, E. myrsinites and E. rigida, which previously had not been included at all on the grounds that they were garden weeds that had not escaped cultivation.
Gamochaeta (Asteraceae): One species newly naturalized in California, G. argyrinea, added to treatment, with incorporation of that species into key to species of Gamochaeta.
Helianthemum (Cistaceae): All members of Helianthemum transferred to Crocanthemum, with change from Helianthemum to Crocanthemum in key to genera of Cistaceae. Helianthemum scoparium split into four terminal taxa.
Hyptis (Lamiaceae): Hyptis emoryi becomes Condea emoryi, leaving no Hyptis in California.
Navarretia (Polemoniaceae): Navarretia sinistra and N. intertexta recircumscribed and new taxa described.
Phacelia (Boraginaceae): Segregation of P. dalesiana to Howellanthus, as H. dalesianus; thorough revision of remainder of Phacelia including some taxonomic changes.
Phoradendron (Viscaceae): Ruling by nomenclature committee resulted in change from P. serotinum and subspp. to P. leucarpum and subspp., with corresponding changes in key to members of Phoradendron.
Thysanocarpus (Brassicaceae): Thysanocarpus curvipes divided into five subspecies. Varieties of T. laciniatus elevated to species.
