Cinara Cupressivora W Atson & Voegtlin, 1999 Other Scientific Names: Order and Family: Hemiptera: Aphididae Common Names: Giant Cypress Aphid; Cypress Aphid
O R E ST E ST PE C IE S R O FIL E F P S P November 2007 Cinara cupressivora W atson & Voegtlin, 1999 Other scientific names: Order and Family: Hemiptera: Aphididae Common names: giant cypress aphid; cypress aphid Cinara cupressivora is a significant pest of Cupressaceae species and has caused serious damage to naturally regenerating and planted forests in Africa, Europe, Latin America and the Caribbean and the Near East. It is believed to have originated on Cupressus sempervirens from eastern Greece to just south of the Caspian Sea (Watson et al., 1999). This pest has been recognized as a separate species for only a short time (Watson et al., 1999) and much of the information on its biology and ecology has been reported under the name Cinara cupressi.

Contributions to the Life-History of Tetraclinis Articu- Lata, Masters, with Some Notes on the Phylogeny of the Cupressoideae and Callitroideae
Contributions to the Life-history of Tetraclinis articu- lata, Masters, with some Notes on the Phylogeny of the Cupressoideae and Callitroideae. BY W. T. SAXTON, M.A., F.L.S., Professor of Botany at the Ahmedabad Institute of Science, India. With Plates XLIV-XLVI and nine Figures in the Text. INTRODUCTION. HE Gum Sandarach tree of Morocco and Algeria has been well known T to botanists from very early times. Some account of it is given by Hooker and Ball (20), who speak of the beauty and durability of the wood, and state that they consider the tree to be probably correctly identified with the Bvlov of the Odyssey (v. 60),1 and with the Ovlov and Ovia of Theo- phrastus (' Hist. PI.' v. 3, 7)/ as well as, undoubtedly, with the Citrus wood of the Romans. The largest trees met with by them, growing in an un- cultivated state, were about 30 feet high. The resin, known as sandarach, is stated to be collected by the Moors and exported to Europe, where it is used as a varnish. They quote Shaw (49 a and b) as having described and figured the tree under the name of Thuja articulata, in his ' Travels in Barbary'; this statement, however, is not accurate. In both editions of the work cited the plant is figured and described as ' Cupressus fructu quadri- valvi, foliis Equiseti instar articulatis '. Some interesting particulars of the use of the timber are given by Hansen (19), who also implies that the embryo has from three to six cotyledons. Both Hooker and Ball, and Hansen, followed by almost all others who have studied the plant, speak of it as Callitris qtiadrivalvis. -

J., Martínez J. F., Buhagiar J. (2013). Genetic structure of Tetraclinis articulata, an endangered conifer of the western Mediter- ranean basin. Silva Fennica vol. 45 no. 5 article id 1073. 14 p. Highlights • The employment of ISSR molecular markers has shown moderate genetic diversity and high genetic differentiation in Tetraclinis articulata. • Genetic structure of populations seems to be influenced by the anthropogenic use of this species since historical times, or alternatively, by the complex palaeogeographic history of the Mediterranean basin. • Results could be used to propose management policies for conservation of populations. Abstract Tetraclinis articulata (Vahl) Masters is a tree distributed throughout the western Mediterranean basin. It is included in the IUCN (International Union for Conservation of Nature) red list, and protected by law in several of the countries where it grows. In this study we examined the genetic diversity and genetic structure of 14 populations of T. articulata in its whole geographic range using ISSR (inter simple sequence repeat) markers. T. articulata showed moderate genetic diversity at intrapopulation level and high genetic differentiation. The distribution of genetic diversity among populations did not exhibit a linear pattern related to geographic distances, since all analyses (principal coordinate analysis, Unweighted pair group method with arithmetic mean dendrogram and Bayesian structure analysis) revealed that spanish population grouped with Malta and Tunisia populations. -
Eastern North American Plants in Cultivation
Eastern North American Plants in Cultivation Many indigenous North American plants are in cultivation, but many equally worthy ones are seldom grown. It often ap- pears that familiar native plants are taken for granted, while more exotic ones - those with the glamor of coming from some- where else - are more commonly cultivated. Perhaps this is what happens everywhere, but perhaps this attitude is a hand- me-down from the time when immigrants to the New World brought with them plants that tied them to the Old. At any rate, in the eastern United States some of the most commonly culti- vated plants are exotic species such as Forsythia species and hy- brids, various species of Ligustrum, Syringa vulgaris, Ilex cre- nata, Magnolia X soulangiana, Malus species and hybrids, Acer platanoides, Asiatic rhododendrons (both evergreen and decidu- ous) and their hybrids, Berberis thunbergii, Abelia X grandi- flora, Vinca minor, and Pachysandra procumbens, to mention only a few examples. This is not to imply, however, that there are few indigenous plants that have "made the grade," horticulturally speaking, for there are many obvious successes. Some plants, such as Cornus florida, have been adopted immediately and widely, but others, such as Phlox stolonifera ’Blue Ridge’ have had to re- ceive an award in Europe before drawing the attention they de- serve here, much as American singers used to have to acquire a foreign reputation before being accepted as worthwhile artists. Examples among the widely grown eastern American trees are Tsuga canadensis; Thuja occidentalis; Pinus strobus (and other species); Quercus rubra, Q. palustris, and Q. -

XXX CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ____________________ Eighteenth meeting of the Conference of the Parties Colombo (Sri Lanka), 23 May – 3 June 2019 CONSIDERATION OF PROPOSALS FOR AMENDMENT OF APPENDICES II1 A. Proposal To list the species Widdringtonia whytei in CITES Appendix II without annotation specifying the types of specimens to be included, in order to include all readily recognizable parts and derivatives in accordance with Resolution Conf. 11.21 (Rev. CoP17). On the basis of available trade data and information it is known that the regulation of trade in the species is absolutely necessary to avoid this critically endangered species, with major replantation efforts underway, becoming eligible for inclusion in Appendix I in the very near future.

Public Lands Profile: Big Hammock
Public Lands Profile: Big Hammock A Land of Dramatic Contrasts Across its 800 acres, Big Hammock Natural Area showcases a fascinating diversity of natural communities of the Lower Atlantic Coastal Plain. For this reason, it was secured by the State of Georgia in 1973, and in 1976 was designated a National Natural Landmark. Despite past harvest of the native longleaf pine and extensive livestock grazing, significant habitat for rare plant and animal species remains intact. A hammock is a rise in elevation of an otherwise flat landscape. Big Hammock Natural Area is dominated by an ancient sand dune that rises from the Altamaha River floodplain to 100 feet above sea level. Between 15,000 to 30,000 years ago, water levels of the Altamaha River fluctuated more than they do now. The river was composed of many smaller braided channels in a sandy bed. During times of drought, the sands would be exposed and transported by dominant winds to the northeast side of the river, forming the dunes that remain today. Similar riverine dunes are occasional throughout Georgia’s Atlantic Coastal Plain on other rivers, such as the Ohoopee and the Ocmulgee, and form a unique part of Georgia’s landscape. It is this sand dune which underlies the natural diversity of Big Hammock NA. The ancient topography causes extreme environmental conditions that morph the vegetation into dramatic contrasts. Evergreen hardwood forest dominates the deep sands of the hammock. Natural fire is suppressed by the Altamaha River on the south side, encouraging the persistence of this fire-intolerant forest type.
