Printed by Premier Graphics: www.premiergraphics.biz FREMONTIA VOLUME 35:1, WINTER 2007 CONTENTS THE “NOSE” OF CALIFORNIA: AN IMPORTANT PART OF THE STATE’S PLANT DIVERSITY by Sarah J. De Groot........................................................ 3 The Whipple Mountains are the easternmost part of California. Surprisingly, this distinc- tive mountain range had not been the subject of a thorough botanical inventory until Sarah De Groot undertook the project for her recent Master’s thesis. In this article she shares some of her discoveries about unusual plants from the “nose” of California. INVASIVE PLANTS IMPACT CALIFORNIA NATIVE PLANTS USED IN TRADI- TIONAL BASKETRY by Jeanine M. Pfeiffer & Elizabeth Huerta Ortiz .......... 7 This innovative article connects the biological issue of invasive species to the cultural concerns of traditional basketry. Invasive plants are causing many problems affecting both production and producers of traditional baskets—from elimination of habitat for desirable plants to health problems for artisans caused by chemicals used to control weedy species. NATIVE GRASSES IN SOUTHERN CALIFORNIA GARDENS by Barbara Eisenstein .................................................................................. 14 Interest in gardening with perennial grasses continues unabated. These grasses can and should be a part of all gardens as they bring movement, form, and texture to the landscape. The author-photographer of this issue’s photo-essay demonstrates the beauty and dynamic nature of these easily grown and essential components of Southern California gardens. GRADY LINDER WEBSTER: 1927-2005 by Marcel Rejmánek ................... 16 Grady Webster was a prominent botanist at the University of California, Davis, for 39 years. He is widely known and published in botanical circles, particularly for his work with the Euphorbiaceae (including a highly regarded monograph of the genus Phyllanthus, and a realignment of the family into five subfamilies). Grady also inspired many students with his field-based California Floristics class. GROWING NATIVES: CALIFORNIA BUCKEYE AS BONSAI by Elmer Grossman ...................................................................................... 19 One might not expect that California buckeye would be a satisfactory bonsai subject, but the author shares his 40 years of experience with such a specimen. This discussion of such an unusual horticultural use of one of our native plants may lead others to further sharing and experimentation. RE-VISITING THE “SPARKLERS” OF CORTE MADERA by Lucy A. Dueck ...20 The 1980 discovery of a disjunct population of Spiranthes porrifolia in San Diego County leads the author on a hunt to find these plants.

This is the second largest family in the flora area after Asteraceae. A total of 97 taxa in 46 genera of grasses are included in this publication, which includes ones established and reproducing in the modern flora (86 taxa in 43 genera), some occurring at the margins of the flora area or no long known from the area, and ice age fossils. At least 28 taxa are known by fossils recovered from packrat middens, five of which have not been found in the modern flora: little barley ( Hordeum pusillum ), cliff muhly ( Muhlenbergia polycaulis ), Paspalum sp., mutton bluegrass ( Poa fendleriana ), and bulb panic grass ( Zuloagaea bulbosa ). Non-native grasses are represented by 27 species, or 28% of the modern grass flora.

A. 2Current address: Division of Biological Sciences and Bond Life Sciences Center, University of Missouri, Columbia, Missouri 65211, U. S. A. Authors for correspondence ([email protected]; [email protected]) Abstract—Cryptantha, an herbaceous plant genus of the Boraginaceae, subtribe Amsinckiinae, has an American amphitropical disjunct distri- bution, found in western North America and western South America, but not in the intervening tropics. In a previous study, Cryptantha was found to be polyphyletic and was split into five genera, including a weakly supported, potentially non-monophyletic Cryptantha s. s. In this and subsequent studies of the Amsinckiinae, interrelationships within Cryptantha were generally not strongly supported and sample size was generally low. Here we analyze a greatly increased sampling of Cryptantha taxa using high-throughput, genome skimming data, in which we obtained the complete ribosomal cistron, the nearly complete chloroplast genome, and twenty-three mitochondrial genes. Our analyses have allowed for inference of clades within this complex with strong support. The occurrence of a non-monophyletic Cryptantha is confirmed, with three major clades obtained, termed here the Johnstonella/Albidae clade, the Maritimae clade, and a large Cryptantha core clade, each strongly supported as monophyletic. From these phylogenomic analyses, we assess the classification, character evolution, and phylogeographic history that elucidates the current amphitropical distribution of the group.

Milchunas General Technical Report RMRS-GTR-169 April 2006 Milchunas, Daniel G. 2006. Responses of plant communities to grazing in the southwestern United States. Gen. Tech. Rep. RMRS-GTR-169. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 126 p. Abstract Grazing by wild and domestic mammals can have small to large effects on plant communities, depend- ing on characteristics of the particular community and of the type and intensity of grazing. The broad objective of this report was to extensively review literature on the effects of grazing on 25 plant commu- nities of the southwestern U.S. in terms of plant species composition, aboveground primary productiv- ity, and root and soil attributes. Livestock grazing management and grazing systems are assessed, as are effects of small and large native mammals and feral species, when data are available. Emphasis is placed on the evolutionary history of grazing and productivity of the particular communities as deter- minants of response. After reviewing available studies for each community type, we compare changes in species composition with grazing among community types. Comparisons are also made between southwestern communities with a relatively short history of grazing and communities of the adjacent Great Plains with a long evolutionary history of grazing. Evidence for grazing as a factor in shifts from grasslands to shrublands is considered. An appendix outlines a new community classification system, which is followed in describing grazing impacts in prior sections.

The basin is bounded by Havasu Lake on the east and by nonwater-bearing rocks of the Sacramento Mountains on the north, of the Chemehuevi Mountains on the northeast, of the Whipple Mountains on the southeast, of the Turtle Mountains on the west and south (Bishop 1963). The valley is drained by Chemehuevi Wash to Havasu Lake. Annual average precipitation ranges from about 4 to 6 inches. Hydrogeologic Information Water Bearing Formations Groundwater in the basin is found in alluvium and the Bouse Formation. Alluvium. Holocene age younger alluvium, which is found in washes and the floodplain of the Colorado River, is composed of sand, silt and gravel (Metzger and Loeltz 1973). Older alluvium consists of unconsolidated, fine- to coarse-grained sand, pebbles, and boulders with variable amounts of silt and clay. Bouse Formation. The Pliocene age Bouse Formation is composed of a basal limestone bed overlain by interbedded clay, silt, and sand. Thickness of the formation reaches 254 feet (Metzger and Loeltz 1973). The formation is underlain by locally derived fanglomerate and overlain by alluviums of the Colorado River and its tributaries. Restrictive Structures An unnamed fault crosses a portion of the southern side of the basin (Bishop 1963), but it is not known whether or not this fault impedes groundwater flow in the basin.

    Flora of the San Pedro Riparian National Conservation Area, Cochise County, Arizona

    Flora of the San Pedro Riparian National Conservation Area, Cochise County, Arizona Elizabeth Makings School of Life Sciences, Arizona State University, Tempe, AZ Abstract—The flora of the San Pedro Riparian National Conservation Area (SPRNCA) consists of 618 taxa from 92 families, including a new species of Eriogonum and four new State records. The vegetation communities include Chihuahuan Desertscrub, cottonwood-willow riparian cor- ridors, mesquite terraces, sacaton grasslands, rocky outcrops, and cienegas. Species richness is enhanced by factors such as perennial surface water, unregulated flood regimes, influences from surrounding floristic provinces, and variety in habitat types. The SPRNCA represents a fragile and rare ecosystem that is threatened by increasing demands on the regional aquifer. Addressing the driving forces causing groundwater loss in the region presents significant challenges for land managers. potential value of a species-level botanical inventory may not Introduction be realized until well into the future. Understanding biodiversity has the potential to serve a unifying role by (1) linking ecology, evolution, genetics and biogeography, (2) elucidating the role of disturbance regimes Study Site and habitat heterogeneity, and (3) providing a basis for effec- tive management and restoration initiatives (Ward and Tockner San Pedro Riparian National 2001).
