A detailed description, illustrations, and discussion concerning morphologically similar and phylogenetically closely related species are provided for each species. From light and scanning electron microscopy observations C. diebuensis is characterized by the nailhead to peltate aeciospores, with separated stilt-like base. C. zhuoni- ensis differs from other known Chrysomyxa species in the annulate aeciospores with distinct longitudinal smooth cap at ends of spores, as well as with a broken, fissured edge. Analysis based on internal transcribed spacer region (ITS) partial gene sequences reveals that the two species cluster as a highly supported group in the phylogenetic trees. Correlations between the morphological and phylogenetic features are discussed. Illustrations and a detailed description are also provided for the aecia of C. succinea in China for the first time. Keywords: aeciospores, molecular phylogeny, spruce needle rust, taxonomy Introduction Picea asperata Mast.is native to western China, widely distributed in Qinghai, Gansu, Shaanxi and western Sichuan. -
Japanese Maples – Acer Spp
Japanese Maples – Acer spp. Known for their astounding variety in color, texture and habit, Japanese Maples are easygoing and adaptable and belong in every garden. If you already have one, think about adding another! for every site, a japanese maple! • Botanists count twenty-three species to include under the common heading of Japanese Maple. The largest group is Acer palmatum and its cultivars, followed by Acer japonicum. The numerous cultivars of Acer palmatum are further divided into seven groups which are mostly defined by leaf-shape. • In addition to variation in leaf-shape, Japanese Maples come in an array of sizes, growth habits, color ranges, and full sun to part shade preference. They add structure, contrast, texture, and beauty to any garden. • Carefully evaluate your chosen planting spot: Japanese maples require a slightly acid, sandy loam, with medium moisture and good drainage. Regular leafed varieties take full sun better than laceleaf types, but all Japanese Maples will be happy with at least some afternoon shade, since St. Louis summer sun is hot, strong and humid. • Remember that plants grow outwards as well as upwards and site appropriately. Take into account proximity to any buildings and any overhead limits. Some pruning is possible but should not be a necessary task. • The main requirement of a Japanese Maple is a uniform supply of water. They are not happy with very wet periods followed by long, dry periods or vice versa. Most will need supplemental water in the St. Louis summers. Japanese Maples in planters have this same need for consistency – be careful that they do not become waterlogged! prepare your site, plant your tree • Japanese Maples are easy to plant. -

Fagus Sylvatica (Common Beech)
Fagus sylvatica Common Beech Fagus sylvatica is a large deciduous tree with smooth grey bark and a broad, spreading crown, leaves are corrugated, broadly elliptic, changing colour from yellow-green in spring, to a rich copper-russet in autumn. Few plants, except fungi, will survive under it due to the close spacing of its foliage which casts a dense shade in the summer. Flowers are small and green which are followed by a bristly fruit called beech mast which are popular with a variety of wildlife. It makes a superb hedge/ screen as its dense green foliage holds well and often the brown leaves of autumn will hang onto the branches until new foliage emerges giving year round screening. The tree is a good choice for woodland or parkland planting.

Non-Native Trees and Large Shrubs for the Washington, D.C. Area
Green Spring Gardens 4603 Green Spring Rd ● Alexandria ● VA 22312 Phone: 703-642-5173 ● TTY: 703-803-3354 www.fairfaxcounty.gov/parks/greenspring NON - NATIVE TREES AND LARGE SHRUBS FOR THE WASHINGTON, D.C. AREA Non-native trees are some of the most beloved plants in the landscape due to their beauty. In addition, these trees are grown for the shade, screening, structure, and landscape benefits they provide. Deciduous trees, whose leaves die and fall off in the autumn, are valuable additions to landscapes because of their changing interest throughout the year. Evergreen trees are valued for their year-round beauty and shelter for wildlife. Evergreens are often grouped into two categories, broadleaf evergreens and conifers. Broadleaf evergreens have broad, flat leaves. They also may have showy flowers, such as Camellia oleifera (a large shrub), or colorful fruits, such as Nellie R. Stevens holly. Coniferous evergreens either have needle-like foliage, such as the lacebark pine, or scale-like foliage, such as the green giant arborvitae. Conifers do not have true flowers or fruits but bear cones. Though most conifers are evergreen, exceptions exist. Dawn redwood, for example, loses its needles each fall. The following are useful definitions: Cultivar (cv.) - a cultivated variety designated by single quotes, such as ‘Autumn Gold’. A variety (var.) or subspecies (subsp.), in contrast, is found in nature and is a subdivision of a species (a variety of Cedar of Lebanon is listed). Full Shade - the amount of light under a dense deciduous tree canopy or beneath evergreens. Full Sun - at least 6 hours of sun daily. -
Genetic Diversity and Conservation of Picea Chihuahuana Martínez: a Review

Received 20 January, 2014; Accepted 16 June, 2014 The conservation of genetic diversity in tree populations is an essential component of sustainable forest management. Picea chihuahuana Martínez is an endemic conifer species in Mexico and is considered to be endangered. P. chihuahuana covers a total area of no more than 300 ha at the Sierra Madre Occidental, a mountain range that harbor a high diversity of tree species. There are 40 populations of the species that have been identified in the region, and it cannot be found elsewhere. These populations form clusters within gallery forests and are usually associated with eight other tree genera. The P. chihuahuana community is mostly well preserved. Owing to its remarkable characteristics and high conservation value, P. chihuahuana has been the subject of several studies aimed at learning more about the genetic structure, ecology and potential effects of climate change. However, the overall applicability of such studies is to confirm a dataset to develop management tools to help decision makers and to implement preservation and conservation strategies using genetic diversity. -
