    EENY-360 Cypress Weevil, Eudociminus mannerheimii (Boheman) (Coleoptera: Curculionidae)1 Albert E. Mayfield, III2 Introduction The cypress weevil, Eudociminus mannerheimii (Boheman), is a native insect that breeds primarily in scarred, weak- ened, or fallen bald cypress (Taxodium distichum [L.] L.C. Rich) and pond cypress (T. ascendens Brongn.). In Florida, adult feeding has caused limited wounding and girdling of pond cypress stump sprouts and planted seedlings. Small diameter bald cypress nursery stock has also been damaged by larvae tunneling through the main stem and root collar. Apart from entries in species checklists and catalogs, published information about the cypress weevil is extremely limited (Hopkins 1904, Blatchley and Leng 1916, Baker and Bambara 1999). Although the cypress weevil has not been a frequent pest of major economic importance, its occasional damage should be recognized, and the lack of information regarding its biology, potential hosts, and management, warrants further research. Figure 1. Adult cypress weevil, Eudociminus mannerheimii (Boheman), dorsal view. Distribution Credits: Lyle Buss, University of Florida The cypress weevil is reported to range from New York to Florida and Louisiana (AL, DC, FL, GA, LA, MS, NC, NJ, NY) (O’Brien and Wimber 1982).

(May 2007) Geoffrey Carlile Denny, B.S., Texas A&M University; M.A., The University of Texas Chair of Advisory Committee: Dr. Michael A. Arnold Taxodium distichum (L.) Rich. is a widely adaptable, long-lived tree species for landscape use. It is tolerant of substantial soil salt levels, but tends to defoliate in periods of extended or severe drought, when leaves come into contact with salty irrigation water, and tends to develop chlorosis on high pH soils. The purpose of this research was to identify provenances which may yield genotypes tolerant of these stresses. The appropriate name for baldcypress is Taxodium distichum (L.)

Grimm et al.; Fables and Foibles of the Coexistence Approach Abstract The “Coexistence Approach” is a mutual climate range (MCR) technique combined with the nearest-living relative (NLR) concept. It has been widely used for palaeoclimate reconstructions based on Eurasian plant fossil assemblages, most of them palynofloras (studied using light microscopy). The results have been surprisingly uniform, typically converging to subtropical, per-humid or monsoonal conditions. Studies based on the coexistence approach have had a marked impact in literature, generating over 10,000 citations thus far.

  • Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part I Cunninghamioideae, Athrotaxoideae, Taiwanioideae, Sequoioideae, Taxodioideae
    1 2 Bull. CCP 3 (3): 117-136. (12.2014) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part I Cunninghamioideae, Athrotaxoideae, Taiwanioideae, Sequoioideae, Taxodioideae Summary Seed cone morphology of the basal Cupressaceae (Cunninghamia, Athrotaxis, Taiwania, Metasequoia, Sequoia, Sequoiadendron, Cryptomeria, Glyptostrobus and Taxodium) is presented at pollination time and at maturity. These genera are named here taxodiaceous Cupressaceae (= the former family Taxodiaceae, except for Sciadopitys). Some close relationships exist between genera within the Sequoioideae and Taxodioideae. Seed cones of taxodiaceous Cupressaceae consist of several bract-/seed scale-complexes. The cone scales represent aggregation of both scale types on different levels of connation. Within Cunninghamia and Athrotaxis the bulges growing out of the cone scales represents the distal tip of the seed scale, which has been fused recaulescent with the adaxial part of the bract scale. In Athrotaxis a second bulge, emerging on the distal part of the cone scale, closes the cone. This bulge is part of the bract scale. Related conditions are found in the seed cones of Taiwania and Sequoioideae, but within these taxa bract- and seed scales are completely fused with each other so that vegetative parts of the seed scale are not recognizable. The ovules represent the only visible part of the seed scale. Within taxodiaceous Cupressaceae the number of ovules is increased compared to taxa of other conifer families. It is developed most distinctly within the Sequoioideae, where furthermore more than one row of ovules appears. The rows develop centrifugally and can be interpreted as short-shoots which are completely reduced to the ovules in the sense of ascending accessory shoots.

Mill3 Trees evergreen, semievergreen, or deciduous, monoecious; trunk straight; main branches ± whorled. Leaves spirally arranged or scattered (decussate in Metasequoia), monomorphic, dimorphic, or trimorphic on same tree, lanceolate, subulate, scalelike, or linear. Microsporophylls and cone scales spirally arranged (decussate in Metasequoia).

Seed cones terminal or borne near apex of previous year’s growth, ripening in 1st year, persistent or late deciduous; cone scales developing after ovules originate in bract axils; bracts and cone scales usually spirally aranged (decussate in Metasequoia), sessile, opening when ripe (falling in Taxodium), semiconnate and free only at apex, or completely united; bracts occasionally rudimentary (in Taiwania); ovules 2–9 per bract axil, erect or pendulous; cone scales of mature cones flattened or shield-shaped, woody or leathery, 2–9-seeded on abaxial side. Seeds flat or triangular, wingless (in Taxodium), narrowly winged all round or on 2 sides, or with a long wing on proximal part. Cotyledons 2–9. 2n = 22*.

However, the two groups are kept as separate families here for pragmatic reasons.

The total solvent extract solutions were analyzed as the free and derivatized products by gas chromatography-mass spectrometry to identify the compounds, which comprised minor mono- and sesquiterpenoids, and dominant di- and triterpenoids, plus aliphatic lipids (e.g., n-nonacosan-10-ol). Ferruginol, 7α-p- cymenylferruginol, and chamaecydin were the major characteristic markers for the Taxodioideae conifer subfamily. The mass spectrometric data can aid polar compound elucidation in environmental, geological, archeological, forensic and pharmaceutical studies.

Introduction Natural products, especially terpenoids or their derivatives, are preserved in the ambient environment or geological record.

  • 26 Extreme Trees Pub 2020
    Publication WSFNR-20-22C April 2020 Extreme Trees: Tallest, Biggest, Oldest Dr. Kim D. Coder, Professor of Tree Biology & Health Care / University Hill Fellow University of Georgia Warnell School of Forestry & Natural Resources Trees have a long relationship with people. They are both utility and amenity. Trees can evoke awe, mysticism, and reverence. Trees represent great public and private values. Trees most noticed and celebrated by people and communities are the one-tenth of one-percent of trees which approach the limits of their maximum size, reach, extent, and age. These singular, historic, culturally significant, and massive extreme trees become symbols and icons of life on Earth, and our role model in environmental stewardship and sustainability. What Is A Tree? Figure 1 is a conglomeration of definitions and concepts about trees from legal and word definitions in North America. For example, 20 percent of all definitions specifically state a tree is a plant. Concentrated in 63% of all descriptors for trees are four terms: plant, woody, single stem, and tall. If broad stem diameter, branching, and perennial growth habit concepts are added, 87% of all the descriptors are represented. At its most basic level, defining a tree is not species based, but is a structural definition. A tree is represented by a type of plant architecture recognizable by non-technical people. The most basic concepts for defining a tree are — a large, tall, woody, perennial plant with a single, unbranched, erect, self-supporting stem holding an elevated and distinct crown of branches, and which is greater than 10 feet in height and greater than 3 inches in diameter.
