CHARACTERISTICS OF TEN TROPICAL HARDWOODS FROM CERTIFIED FORESTS IN BOLIVIA PART I WEATHERING CHARACTERISTICS AND DIMENSIONAL CHANGE R. Sam Williams Supervisory Research Chemist Regis Miller Botanist and John Gangstad Technician USDA Forest Service Forest Products Laboratory1 Madison, WI 53705-2398 (Received July 2000) ABSTRACT Ten tropical hardwoods from Bolivia were evaluated for weathering performance (erosion rate, dimensional stability, warping, surface checking, and splitting). The wood species were Amburana crarensis (roble), Anudenanthera macrocarpa (curupau), Aspidosperma cylindrocarpon Cjichituriqui), Astronium urundeuva (cuchi), Caesalpinia cf. pluviosa (momoqui), Diplotropis purpurea (sucupira), Guihourriu chodatiuna (sirari), Phyllostylon rhamnoides (cuta), Schinopsis cf. quebracho-colorudo (soto), and Tabeb~liuspp. (lapacho group) (tajibo or ipe). Eucalyptus marginatu Cjarrah) from Australia and Tectonu grandis (teak), both naturally grown from Burma and plantation-grown from Central America, were included in the study for comparison. The dimensional change for the species from Bolivia, commensurate with a change in relative humidity (RH) from 30% to 90%, varied from about 1.6% and 2.0% (radial and tangential directions) for Arnburunu cer~ren.risto 2.2% and 4.1% (radial and tangential) for Anadenanthera macrocarpu. The dimensional change for teak was 1.3% and 2.5% (radial and tangential) for the same change in relative humidity. None of the Bolivian species was completely free of warp or surface checks; however, Anadenanthera macrocarpu, Aspidosperma cy- lindrocurpon, and Schinopsis cf. quebracho-colorado performed almost as well as teak. The erosion rate of several of the wood species was considerably slower than that of teak, and there was little correlation between wood density and erosion rate. Part 2 of this report will include information on the decay resistance (natural durability) of these species. -
Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607)
Complete Index of Common Names: Supplement to Tropical Timbers of the World (AH 607) by Nancy Ross Preface Since it was published in 1984, Tropical Timbers of the World has proven to be an extremely valuable reference to the properties and uses of tropical woods. It has been particularly valuable for the selection of species for specific products and as a reference for properties information that is important to effective pro- cessing and utilization of several hundred of the most commercially important tropical wood timbers. If a user of the book has only a common or trade name for a species and wishes to know its properties, the user must use the index of common names beginning on page 451. However, most tropical timbers have numerous common or trade names, depending upon the major region or local area of growth; furthermore, different species may be know by the same common name. Herein lies a minor weakness in Tropical Timbers of the World. The index generally contains only the one or two most frequently used common or trade names. If the common name known to the user is not one of those listed in the index, finding the species in the text is impossible other than by searching the book page by page. This process is too laborious to be practical because some species have 20 or more common names. This supplement provides a complete index of common or trade names. This index will prevent a user from erroneously concluding that the book does not contain a specific species because the common name known to the user does not happen to be in the existing index. -

What can I say, just keep shoveling! So much for a mild win- ter. As most of you are aware, the February meeting was canceled because of weath- er. If you didn't get the email notice, I apologize. It may have gone out on an older mailing list. So that being a situa- tion, if you need to send info out to club members, make sure you have the latest list. You can get it from Randy. If you have bowls yet for "Feed My People " please contact me at [email protected] and I will get them from you. Each of you who are signed up to do a demo at a club meeting, please just move your demo forward one month. If that can't work, let me know. We are always looking for new ideas for demos for club meetings. If you would like a demonstration on a given area of wood turning, let me know and we will try to get in in the schedule. For those of you who like to turn natural edge bowls, now is the time to cut the trees before the sap starts to flow. The bark is less likely to loosen. Obviously because on no meeting this month our letter will be somewhat shorter. I give Tom credit for his creativity in making it informative, Thanks Tom ! Well again as Bugs Bunny sez, "That's all folks" Prez Duane. -
The Wood Cross Sections of Hermann Nördlinger (1818–1897)
IAWA Journal, Vol. 29 (4), 2008: 439–457 THE WOOD CROSS SECTIONS OF HERMANN NÖRDLINGER (1818–1897) Ben Bubner Leibniz-Zentrum für Agrarlandschaftsforschung (ZALF) e.V., Institut für Landschaftsstoffdynamik, Eberswalder Str. 84, 15374 Müncheberg, Germany [E-mail: [email protected]] SUMMARY Hermann Nördlinger (1818–1897), forestry professor in Hohenheim, Germany, published a series of wood cross sections in the years 1852 to 1888 that are introduced here to the modern wood anatomist. The sec- tions, which vary from 50 to 100 μm in thickness, are mounted on sheets of paper and their quality is high enough to observe microscopic details. Their technical perfection is as remarkable as the mode of distribution: sections of 100 wood species were presented in a box together with a booklet containing wood anatomical descriptions. These boxes were dis- tributed as books by the publisher Cotta, from Stuttgart, Germany, with a maximum circulation of 500 per volume. Eleven volumes comprise 1100 wood species from all over the world. These include not only conifers and broadleaved trees but also shrubs, ferns and palms representing a wide variety of woody structures. Excerpts of this collection were also pub- lished in Russian, English and French. Today, volumes of Nördlingerʼs cross sections are found in libraries throughout Europe and the United States. Thus, they are relatively easily accessible to wood anatomists who are interested in historic wood sections. A checklist with the content of each volume is appended. Key words: Cross section, wood collection, wood anatomy, history. INTRODUCTION Wood scientists who want to distinguish wood species anatomically rely on thin sec- tions mounted on glass slides and descriptions in books that are illustrated with micro- photographs. -

Most are seen 8 to 12 feet tall with a beautiful array of multiple trunks and a rounded canopy much like that of a mature crape-myrtle. The one to two-inch-long, leathery, dark green leaves are joined at many times throughout the year by the production of large clusters of bluish purple flowers, the old flowers fading to a light silvery-blue and creating a shimmering haze over the rounded canopy. These flowers are followed by small, heart-shaped, yellow orange berries, appearing on the tree at the same time as the bluish purple flowers and creating a lovely sight.

Carapa Guianensis Aublet Meliaceae Crabwood, Bastard Mahogany, Andiroba
Carapa guianensis Aublet Meliaceae crabwood, bastard mahogany, andiroba LOCAL NAMES English (bastard mahogany,crabwood,carapa); French (cabirma de Guinea,bois rouge,carapa,andiroba); Spanish (andiroba,caobilla,najesi,cedro macho,masábalo,cabrima de guiana); Trade name (bastard mahogany,crabwood,andiroba) BOTANIC DESCRIPTION Carapa guianensis is a deciduous or semi-evergreen, monoecious, medium-sized to large trees up to 35 (max. 55) m tall; bole straight and cylindrical; branchless up to 20 (max. 30) m; up to 100 (max. 200) cm in diameter, sometimes fluted, with short buttresses up to 2 m high. Bark surface flaking into squarish scales or in horizontal strips, light grey to greyish brown or dark brown, sometimes reddish; inner bark fibrous, red or pinkish brown. Young plants produce taproots but the trees tend to become surface rooted. Leaves alternate, paripinnate with a dormant glandular leaflet at the apex, exstipulate; leaflets opposite, entire. Shows gigantic leaves in the monocaulous juvenile stage, decreasing in size when branching is initiated. Flowers small, white, borne in a large, axillary or subterminal thyrse; unisexual but with well-developed vestiges of the opposite sex; tetramerous to pentamerous (max. sextamerous); calyx lobed almost to the base; petals slightly contorted. Fruit dehiscent, 4-lobed, pendulous, subglobose, woody capsule containing 2-4 seeds in each lobe. Seeds smooth, pale brown, angular, with woody sarcotesta. BIOLOGY Flowering period depends heavily on the climate but is usually concentrated in 1 short period per year. Pollination is probably by insects; trees are often found swarming with ants visiting extrafloral nectaries at shoot apices and leaflet tips. Usually only 1-2 fruits in an inflorescence mature in 8-12 months.
