  • Thierry Lamant
    l1~ternational Oaks ' ' •• e Probl by Thierry Lamant Office National des Forets Conservatoire de Resources Genetiques Ardon, France and Guy Sternberg Starhill Forest Arboretum NAPPC Oak Reference Collectioit Petersburg, Illinois USA he nomenclature of the genus Quercus is a nightmare for non-taxonomists. It can be very difficult even for skilled scienti. ts to navigate the jungle of Latin names and conflicting authors and some may find their research results, botanical collections, herbaria, or nursery catalogs con1promised by confusion. Here is an overview of the situ­ ation, presented by non-taxonomists for the benefit of other non-taxonomists. One of the main difficulties encountered with oak name involves different authors applying the sa1ne name to differ­ ent species. An exan1ple can be found 1n the trees for1nerly known as Q. prinus L. in the United States. This old name covered at ]east two different species (Q.n1ontana Willd. in common usage, but perhaps more correctI y by priority of publication Q.michauxii Nuttall). It is not clear which speci- lnterncztional Oaks tnen Linna eus used for his type. In cur­ rent literature, the name Q. prinus is be­ ing discarded for thi s reason. These species have a close relative, the dwarf chestnut oak Q. prinoides L. Among other names, it has been cal1 ed Q. prinus var. pu1nila Michx.

  • Missouri Environment and Garden Newsletter, March 2015
    Missouri March 2015 Volume 21, Number 3 Mizzou Plant Diagnostic Clinic 2015 The Mizzou Plant Diagnostic Clinic (PDC) is open all year to receive plant samples that are affected by a disease or disorder. The PDC can also identify pesky weeds, plants of interest, mushrooms and insects or spiders. Last year the Clinic processed 445 samples, over 50% of these consisted of ornamentals, turf, and fruit or vegetable producing plants. Diseases ranged the gamut from anthracnose to wilts, making it an interesting year in the Plant Clinic. In 2014, most woody ornamentals were diagnosed with leaf spots and vascular wilt diseases. Bacterial blights and root rots were most problematic in herbaceous ornamentals. On zoysiagrass lawns, both chinch bugs and large patch were most often diagnosed. The food producing plants had a myriad of issues ranging from root rots to leaf spots. The PDC is open all year. It is encouraged that you get a diagnosis before applying pesticides or other controls, as this will allow for selection of a control measure that will most effectively deal with your precise pest problem. The PDC is open for sample drop off, Monday Figure 1: Oak wilt (Ceratocystis fagacearum) on Nuttall oak through Friday from 9am to 4pm. Sample can also be mailed directly (Quercus texana) Photo by Paul A. Mistretta, USDA Forest to the PDC or dropped off at your local extension office. If possible, Service, Bugwood.org take a picture of the sick plant before digging it up; if several plants are affected a picture of the entire planting is also encouraged.

Buckeye is not customarily separated from other species when manufactured into lumber and can be utilized for the same purposes as aspen, basswood, and sap yellow- poplar. The following description is for yellow buckeye (Aesculus octandra). The Tree Buckeye is a tree 30 to 70 ft (9 to 21 m) high and 2 ft (0.6 m) in diameter. It grows best in rich moist soil along the banks of streams and in river bottoms. Buckeye matures in 60 to 80 years. It is one of the initial trees to leaf-out in the spring.

  • Aesculus Californica (Family: Sapindaceae) Common Names: California Buckeye, California Horse-Chestnut
    Aesculus californica (Family: Sapindaceae) Common Names: California Buckeye, California Horse-chestnut Taxonomic Description: The California Buckeye is a large native, deciduous shrub or tree that is recognized by its broad, round shape and gray bark usually with a moss or lichen coating. The entire tree can grow between 10 to 25 feet tall (about 12 meters). Its compound leaves grow in leaflets of 5 that range from 5 to 17 centimeters and petiole from 1 to 12 centimeters. The leaves are tender to protect from severe weather damaging. This tree is the first to grow leaves in the spring, the last to bloom, and the first to lose its leaves. Flowers of the California Buckeye are grown from erect panicles; they smell sweet and are colored from white to pale pink. Fruits of this tree are capsules from 5 to 8 centimeters long, shaped as figs. Inside these fruits are smooth, round, 2 to 5 centimeters big orange- brown seeds that are poisonous. Growth Form/Habitat/Soil: The California Buckeye is adapted to coarse textured soils and medium textured soils for growth. It has no anaerobic tolerance and low CaCO3 tolerance, high drought tolerance and medium fire tolerance and water use. A pH minimum of 5.5 pH, and a maximum of 7.5 pH in the soil is required. Because the trees are able to grow in crowded, or moist, or even semi-shaded environments, they can commonly be found on dry hills, canyon slopes, and borders of streams. Distribution (geographic): The California Buckeye is native to the state, and is widely distributed within it.

    Tobusch Fishhook Cactus Species Status Assessment - Final SPECIES STATUS ASSESSMENT REPORT FOR TOBUSCH FISHHOOK CACTUS (SCLEROCACTUS BREVIHAMATUS SSP. TOBUSCHII (W.T. MARSHALL) N.P. TAYLOR) February, 2017 Southwest Region U.S. Fish and Wildlife Service Albuquerque, NM Tobusch Fishhook Cactus Species Status Assessment - Final Prepared by Chris Best, Austin Ecological Services Field Office, Suggested citation: U.S. Fish and Wildlife Service. 2017. Species status assessment of Tobusch Fishhook Cactus (Sclerocactus brevihamatus ssp. tobuschii (W.T. Marshall) N.P. Taylor). U.S. Fish and Wildlife Service Southwest Region, Albuquerque, New Mexico. 65 pp. + 2 appendices. i Tobusch Fishhook Cactus Species Status Assessment - Final EXECUTIVE SUMMARY Tobusch fishhook cactus is a small cactus, with curved “fishhook” spines, that is endemic to the Edwards Plateau of Texas. It was federally listed as endangered on November 7, 1979 (44 FR 64736) as Ancistrocactus tobuschii. At that time, fewer than 200 individuals had been documented from 4 sites. Tobusch fishhook cactus is now confirmed in 8 central Texas counties: Bandera, Edwards, Kerr, Kimble, Kinney, Real, Uvalde, and Val Verde. In recent years, over 4,000 individuals have been documented in surveys and monitoring plots. Recent phylogenetic evidence supports classifying Tobusch fishhook cactus as Sclerocactus brevihamatus ssp. tobuschii. It is distinguished morphologically from its closest relative, S. brevihamatus ssp. brevihamatus, on the basis of yellow versus pink- or brown-tinged flowers, fewer radial spines, and fewer ribs. Additionally, subspecies tobuschii is endemic to limestone outcrops of the Edwards Plateau, while subspecies brevihamatus occurs in alluvial soils in the Tamaulipan Shrublands and Chihuahuan Desert. A recent investigation found genetic divergence between the two subspecies, although they may interact genetically in a narrow area where their ranges overlap.
