Synonyms Artemisia abrotanoides Nuttall; A. fischeriana Besser; A. foliosa Nuttall; Crossostephium californicum (Lessing) Rydberg (FNA 2017). C. Common name California sagebrush. The common name refers to its strong, sage-like aroma and endemism to California and Baja California. Other names include: coastal sage, coast sage, coast sagebrush (Painter 2016). D. Taxonomic relationships The FNA (2017) places this species in subgenus Artemisia . The molecular phylogeny of the genus has improved the understanding of relationships among the many species of Artemisia and has, at times, placed the species in subgenus Tridentadae; morphology of the inflorescences and flowers alone does not place this species with its closest relatives (Watson et al. 2002). The detailed phylogeny is not completely resolved (Hayat et al. 2009). E. Related taxa in region There are 18 species and a total of 31 taxa (including infrataxa) of Artemisia in southern California, all of which differ clearly from A. californica in habitat affinity, structure, or both (Munz 1974, Jepson eFlora 2017). Within subgenus Artemisia (as per FNA 2017), A. nesiotica from the Channel Islands is the most similar and was once considered part of A. californica ; it can be distinguished by its wider leaves with flat leaf margins (not rolled under).

    Acmispon Helleri Notes

    Sorrie, B.A. 2015. Notes on morphology of Acmispon helleri (Fabaceae). Phytoneuron 2015-44. 1–3. Published 15 July 2015. ISSN 2153 733X NOTES ON MORPHOLOGY OF ACMISPON HELLERI (FABACEAE) BRUCE A. SORRIE University of North Carolina Herbarium North Carolina Botanical Garden Chapel Hill, North Carolina 27599-3280 ABSTRACT Recent field observations of Acmispon helleri in North Carolina point out a number of discrepancies or omissions regarding published descriptions, including stem color and pubescence, leaflet morphology and vestiture, and corolla color. Degree of foliation strongly corresponds with phenology –– loss of leaves and leaflets over time appears to be common. Acmispon helleri (Britt.) A.A. Heller is the eastern segregate of the western and midwestern A. americanus (Nutt.) Rydb. and is restricted to scattered locations in the piedmont of south-central Virginia, North Carolina, South Carolina, and northeastern Georgia (Weakley 2015). It was formerly placed within Lotus, sometimes as a full species, sometimes as a variety (see Brouillet 2008 and Weakley 2015 for synonymy). Observations of living plants at sites in the lower piedmont of Union County, North Carolina, in 2010 suggest that several morphological characters are at variance with published descriptions. The most detailed description available is that of Wilbur (1963); also very helpful are the illustrations in Chafin (2007). Radford, Ahles, and Bell (1968) followed Wilbur in writing their description. 1. Stem color. Neither Wilbur nor Radford, Ahles, and Bell mention this. In the Union County plants, stems are wholly reddish brown. Branches are green, but often reddish brown basally. 2. Pubescence of stems and branches. Wilbur: stems and branches are "glabrate (especially below) to moderately spreading villous-pubescent." In the Union County plants, stems are sparsely to moderately villous throughout and branches moderately to densely villous.

    Outline of Angiosperm Phylogeny

    Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report.

Chaparral species of California, USA, exhibit three life history types in response to fire: non-sprouters (NS), facultative sprouters (FS), and obligate sprouters (OS). Adult non-sprouters are killed by fire; thus populations reestablish only through fire- stimulated seed germination and seedling recruitment. Facultative sprouters reestablish by both vegetative sprouting and seed germination. Obligate sprouters reestablish only by vegetative sprouting and do not recruit seedlings post-fire. Previous data suggest that post-fire NS and FS seedlings reestablish as open-canopy gap specialists, whereas OS seedlings primarily reestablish in deep shade during fire-free intervals. Their non-refractory seeds are killed by fire. We hypothesized that these differences in life history, compared within the same taxonomic group, would result in a range of relative resistance to water stress such that NS . FS . OS. To test our hypothesis, we estimated resistance to water stress using resistance to xylem cavitation (the water potential at 50% loss in hydraulic conductivity; W50) for stems and roots in nine species of the family Rhamnaceae: Ceanothus megacarpus, C.
