Upper surface of a first-year shoot [C.J. Earle]. Lower surface of the same shoot [C.J. Earle]. Distribution map ( USGS 1999 Taxus brevifolia Nuttall 1849 Common Names Pacific or western yew, mountain mahogany ( Peattie 1950 Taxonomic notes Syn: Taxus baccata Linnaeus subsp. brevifolia (Nuttall) Pilger; T. baccata var. brevifolia (Nuttall) Koehne; T. baccata var. canadensis Bentham; T. bourcieri T. lindleyana A. Murray bis. The name T. baccata Hooker has been misapplied to this species ( Hils 1993 Description Hils 1993 Peattie 1950 , and my pers. obs.). Range Hils 1993 ). See also Thompson et al. . In most of its range it grows as a tree beneath a closed forest canopy in late-successional forests dominated by large conifers such as Pseudotsuga menziesii and Tsuga heterophylla , but in drier open forests of the eastern Cascade Range in Washington (and perhaps elsewhere) it adopts a shrub habit similar to Juniperus communis , forming broad mats that may be several times wider than tall. Big Tree Height 16 m, dbh 146 cm, crown spread 9 m, located near Packwood, Washington ( American Forests 1996 ). I have heard anecdotal reports of larger trees being logged within the past decade.

New Erowid T-shirts available! Join today to get yours. Ethnobotany and Economic Botany of the North American Flora by Charles B. Heiser Jr. When Europeans first arrived, in both eastern and southwestern North America north of Mexico, they found people who were practicing agriculture, much of it with crops from Mexico. Consequently, the use of native wild plants received scant attention. This changed, however, when the Europeans penetrated the areas inhabited by hunters and gatherers. According to R. I. Ford (1986), "the traditional use of plants and animals by American Indians is better documented than for the early peoples of any other continental area of the world." Ford has brought together a number of the significant papers dealing with the use of plants and animals by the native people. Furthermore, archaeological investigations, particularly in the last half century, have also contributed greatly to our understanding of the plants used by the native North Americans. The immigrants to North America from Europe brought the Old World crops to North America, and those plants soon came to be the dominant cultivated crops in northern North America. Many weeds, a few of which were found to serve useful purposes, were also introduced unintentionally.

Dietrich 1824 Common Names abies Taxonomic notes The genus is related most closely to Pinus , but differs markedly even from that. It is a very uniform genus, clearly monophyletic with no aberrant species, so generic segregation has never been suggested ( Farjon 1990 ). There are 33 species treated here, though a careful re-evaluation of the poorly-studied East Asian taxa would probably reduce this number ( Farjon 1990 Sigurgeirsson and Szmidt 1993 ). Classification within the genus is problematic, and no fully satisfactory phylogeny has yet been worked out despite numerous attempts ( Wright 1955 Bobrov 1970 Liu 1982 Page and Hollands 1987 ... Sigurgeirsson and Szmidt 1993 ). Extensive hybrid introgression and gene exchange between a number of species complicates the research; few spruces have well-established barriers to hybridisation.

Luiseño Ethnobotany Home Fall Spring/Summer AIS ... Anthro The Luiseño are the most Southwestern group of Shoshonean people in the greater North American desert. The name Luiseño came from their having lived in close proximity to the Spanish mission San Luis Rey (1798-1834) which is located in northern San Diego County near Oceanside, California. Originally, the Luiseño may have been called Payomkawichum ('The Westerners') by neighboring people and Ataxum ('The People') by themselves. The Luiseño occupied parts of north coastal San Diego County and Riverside County in pre-Hispanic (before 1769) Southern California. It is theorized that the Luiseño came into Southern California approximately 5,000-7,000 years ago during severe altithermals (drought periods) from the Basin areas east of the Sierra Nevada Mountains. Their Shoshonean neighbors like the Cupeño, Cahuilla, Serrano, Gabrieliño and Chemehuevi were part of this migration. The Southern California environment was dominated by scrub plant communities that include the following : COMMUNITY SLOPE GROWTH HABITS TYPICAL PLANTS Coastal Sage Scrub(0-1500') South-facing Drought-decidious;small lvs;phytotoxins

Is Guaiacum sanctum Effective Against Arthritis? An Ethnobotany Case by Eric Ribbens Barbra Burdett , and Angela Green Department of Biological Science Western Illinois University Figure 1: Seeds of Guaiacum sanctum Dr. Beth Tonoany is a tropical population ecologist who has been studying an unusual tree, Guaiacum sanctum , which once grew throughout the dry tropical forests of Central America as well as on some of the Caribbean islands. Guaiacum sanctum produces a wood called lignum vitae , and is known in Costa Rica and other Spanish-speaking countries as . The wood is extremely heavy because it contains extensive deposits of resin ( Howes, 1949 ) and it will sink if placed in water ( Wilson and Eisner, 1968 ). During World War I and II it was extensively harvested for use in the ship-building industry because the wood, which does not split easily, is self-lubricating due to its high resin content. The wood is very durable, and was in high demand for constructing bearing sleeves to support ship propellor shafts ( Scurlock, 1987

CASE TEACHING NOTES for Is Guaiacum sanctum Effective Against Arthritis? An Ethnobotany Case by Eric Ribbens Barbra Burdett , and Angela Green Department of Biological Science Western Illinois University INTRODUCTION / BACKGROUND We designed this case to explore aspects of the process of screening and testing the medicinal value of plants identified by ethnobotanists as having potential health benefits. Specifically, this case is designed to encourage students to apply basic scientific methods of experimentation, analyze the results, and plan subsequent steps. Additionally, we hope that as a result of exploring this case students will have a better understanding of why we cannot use a plant product medicinally simply because anecdotal evidence indicates it has medicinal value. Finally, this case is an illustration of the repeated design, analysis, and hypothesis reevaluating that is central to experimental scientific work. Objectives Specifically, the goals of this case are: to encourage students to think about the lengthy process required before a drug can be made available in Western medicine; to give students practice in designing experiments and analyzing data; and
