  • 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. For further information, see the references on the last page.

Fraga ABSTRACT: We present an annotated catalogue of the vascular flora of the upper Santa Ana River watershed, in the southern San Bernardino Mountains, in southern California. The catalogue is based on a floristic study, undertaken from 2008 to 2010. Approximately 65 team days were spent in the field and over 5,000 collections were made over the course of the study. The study area is ca. 155 km2 in area (40,000 ac) and ranges in elevation from 1402 m to 3033 m. The study area is botanically diverse with more than 750 taxa documented, including 56 taxa of conservation concern and 81 non-native taxa. Vegetation and habitat types in the area include chaparral, evergreen oak forest and woodland, riparian forest, coniferous forest, montane meadow, and pebble plain habitats.

Photos by ODA staff (left and center) and Thomas Kaye (right). If downloading images from this website, please credit the photographer. Family Nyctaginaceae Taxonomic notes Synonyms: Abronia umbellata ssp. breviflora, Abronia umbellata ssp. acutalata, Abronia umbellata var. acutalata, Abronia breviflora, Abronia acutalata The number of taxa included within the Abronia umbellata complex has varied with different treatments of the group. Based on genetic and morphometric studies of A. umbellata populations, we consider A. umbellata var. acutalata to be included within var. breviflora. Plant description Pink sandverbena can be either an annual or occasionally a short-lived perennial. It is a tap-rooted glandular-puberulent forb with few to several prostrate branches up to 1 m (-1.5) long. Leaf blades are fleshy, light green, oval to oblong-ovate with somewhat irregular margins, 2-6 cm long, with slender petioles about as long as the blades. Flowers are grouped in ball-like clusters of 8-20 (average 14-15) subtended by 5 (4) lanceolate involucral bracts, with clusters born at the ends of stalks growing out from the stems. Individual plants produce from one to thousands of flower clusters, depending on conditions. The perianth is glandular-puberulent, the perianth tube greenish or yellowish to pink and 0.6-0.8 cm long. The corolla limbs are pinkish-purple to deep reddish-magenta, 0.5-0.8 cm broad. Flowers have a yellowish-white eyespot 0.25-0.3 cm in diameter surrounding the throat.

    SPECIES Abronia maritima Nutt. ex S. Wats. Family: Nyctaginaceae; NRCS CODE: Gary A. Monroe @ USDA-NRCS PLANTS Database ABMA2 Order: Caryophyllales; Subclass: Caryophyllidae; Class: Magnoliopsida Subspecific taxa None. Synonyms None listed. Common name red sand verbena (CalFlora, USDA PLANTS), sticky sand verbena (CalFlora) Taxonomic relationships Abronia latifolia Eschsch. and A. umbellata Lam. are closely related species (Blancas 2001). Related taxa in region May co-occur with A. latifolia and A. umbellata where distributions overlap. All three occur between Point Arguello, Santa Barbara Co., to Morro Bay in San Luis Obispo Co. (Tilllett 1967). Other CNPS list 4.2, limited distribution. Endemic to California and Baja California. There has been concern that hybridization with the two more widespread, co-occurring species of Abronia together with rapid loss of its coastal dune habitat are making the plants vulnerable to extinction (Blancas 2001). Genetic and morphological studies by Blancas (2001) were consistent with there being a high rate of hybridization with A. umbellata within a few small populations.
