Insert as an Additional Taxa For Quercus macrocarpa: Quercus prinus L. Chestnut Oak (Quercus montana) C This species is also known as Basket Oak, Chêne Châtaignier, Rock Chestnut Oak, Rock Oak, Swamp Chestnut Oak or Tanbark Oak; Chestnut Oak derives this common name from the resemblance of the leaves to those of Castanea spp.; the dark glossy green leaves are oblong to obovate and 5O to 8O (10O) long with coarsely serrate, nearly dentate, margins; these 50N to 60N (90N) tall trees are initially upright oval in habit, becoming more spreading with age; the acorns are fairly large, 1O to 1¼O long, and can create a litter problem in manicured lawns; the bark of Q. prinus is a darker nearly black-brown color compared to the lighter gray bark of Q. michauxii. C Quercus prinus is essentially a more northern version of Q. michauxii that is native predominantly to more upland sites or in well drained soils along stream courses than Q. michauxii; this species is not as tolerant of wet soils as Q. michauxii, but Q. prinus tends to be more drought tolerant. C Chestnut Oak deserves wider testing in the cooler portions of our region; it has a good upright form, rapid growth rate for a Quercus spp., and transplants relatively easily; it is probably useful in USDA zones 5 to 8. C The taxonomy of Q. prinus is somewhat confused with that of Q. michauxii; they are very similar in appearance, but have differing adaptive traits; identification of both species in the trade may be confused, particularly in regions where their native ranges overlap. Quercus michauxii T. Nuttall Swamp Chestnut Oak (Quercus houstoniana, Quercus prinus auct. p.p. non L.) C This species is also known as Basket Oak, Cow Oak, Michaux Oak, Swamp Oak, or White Oak; in our regional landscapes, Q. michauxii is a medium to large, 60N to 70N (120N) tall, deciduous tree that develops an upright oval to rounded crown; some consider the light gray bark to be an asset; the 4O to 7O (10O) long oblong to obovate leaves tend to be broader than those of Q. prinus; they are also coarsely toothed and pubescent beneath; the ¾O to 1¼O long acorns are eaten by wildlife, but may cause litter problems on lawns, sidewalks and drives. C A native of the Southeastern U.S., including East Texas, Q. michauxii is found on wet bottomland sites along water courses or near swamps, hence the common name of Swamp Chestnut Oak; this species may be suitable for use in seasonally poorly drained or compacted soils; plants will tolerate full sun to part shade, but tend to develop chlorosis on high pH soils; trees are useful in USDA zones 6 to 9a(9b). C The specific epithet honors the famous 18th century French plant collector, explorer, and botanist André Michaux. Copyright 2006 with all rights reserved by Michael A.

Beneficial Trees for Wildlife Forestry and Plant Materials Technical Note
United States Department of Agriculture Natural Resources Conservation Service Technical Note No: TX-PM-16-01 August 2016 Beneficial Trees for Wildlife Forestry and Plant Materials Technical Note Background Trees provide shelter and food sources for a wide array of wildlife. White tail deer browse leaves and twigs along with acorns each fall and winter when other food sources are unavailable. More than 100 animal species eat acorns including rabbits, squirrels, wild hog, and gamebirds (Ober 2014). Songbirds and small mammals consume fruits and seeds. Wood peckers (Melanerpes sp.) and red tailed hawk (Buteo jamaicencis) nest in the cavities of hollow or dead trees (Dickson and Connor 1982). Butterflies, moths, and honeybees use trees as larval hosts, nectar sources, and shelter (Hill and Webster 1995). At right is a map illustrating forest types within the Western Gulf Coastal Plain. The Western Gulf Coastal Plain has a diversity of native hardwoods along with three species of southern pines (longleaf (Pinus palustris), shortleaf (Pinus echinata) and loblolly (Pinus taeda). Important native hardwoods used commercially and for wildlife include mockernut hickory (Carya tomentosa), hackberry (Celtis laevigata), green ash (Fraxinus pennsylvanica), black walnut (Juglans nigra), sweetgum (Liquidambar styraciflua), black tupelo (Nyssa sylvatica), white oak (Quercus alba), southern red oak (Quercus falcata), water oak (Quercus nigra), willow oak (Quercus phellos), shumard oak (Quercus shumardii), post oak (Quercus stellata), bald cypress (Taxodium distichum), and American elm (Ulmus americana) (Diggs 2006). 1 Purpose The purpose of this technical note is to assist conservation planners and land managers by providing basic tree establishment information and a list of beneficial wildlife trees (Table 1) when they are planning wildlife and pollinator habitat in east Texas, western Louisiana, southwestern Arkansas, and southeastern Oklahoma.

Quercus Prinus Chestnut Oak1 Edward F
Fact Sheet ST-557 October 1994 Quercus prinus Chestnut Oak1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION Chestnut Oak is a deciduous, native tree which reaches 50 to 60 feet in height with an equal spread when grown in the open (Fig. 1). It is capable of reaching to 100 feet in the woods. The glossy, green, four to eight-inch-long by 1.5 to 3-inch-wide leaves turn to yellow-brown or red-brown in fall before dropping. The large, 1.5-inch-long acorns which fall in October are particularly sweet-tasting, and are relished by many forms of wildlife, such as the grey squirrel, black bear, and white-tailed deer. The attractive dark brown to black bark is deeply ridged and furrowed.

An Updated Infrageneric Classification of the North American Oaks
Article An Updated Infrageneric Classification of the North American Oaks (Quercus Subgenus Quercus): Review of the Contribution of Phylogenomic Data to Biogeography and Species Diversity Paul S. Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L. An Quercus Updated Infrageneric Classification white oaks), the two largest sections of subgenus . We also distill emerging evolutionary and of the North American Oaks (Quercus biogeographic patterns based on the impact of phylogenomic data on the systematics of multiple Subgenus Quercus): Review of the species complexes and instances of hybridization.

Proceedings of the Indiana Academy Of
Analysis of Two Old-growth Forests on Poorly-drained Clermont Soils in Jennings County, Indiana Marion T. Jackson Department of Life Sciences Indiana State University, Terre Haute, Indiana 47809 and William B. Barnes Division of Nature Preserves Indiana Department of Natural Resources, Indianapolis, Indiana 46204 Abstract The canopy tree, shrub and herb strata in Tribbetts and Commiskey Woods in Jennings County, Indiana, were sampled by taking nested 1/40, 1/400 and 1/4,000- hectare rectangular plots, respectively. Both stands have high basal areas (33.6 and 38.2 square meters per hectare) and relatively low stand densities (184 and 242 trees per hectare, respectively). Dominant canopy tree species are Fagus grandifolia Ehrh., followed by Liquidambar styraciflua L. and Acer rubrum L., which collectively com- prise 76 and 69 per cent, respectively, of stand importance. Both stands are very similar in composition to presettlement forests on Clermont soils, and to contem- porary old-growth stands on similar sites. Smilax rotundifolia L., Asimina triloba (L.) Dunal and Lindera benzoin (L.) Blume dominate the shrub layer of both stands. Rhus radicans L., plus the above three shrub species and Nyssa sylvatica Marsh, seedlings dominate the herbaceous stratum. The shrub layer contains 23 and 26 species totally, and the herb layer 39 and 50 species in Tribbetts and Commiskey Woods, respectively. Introduction Interest in locating and describing additional natural areas in Indiana remains at a high level. As a result of this continuing search, some 30 new areas have been reported since Natural Areas in Indiana and their Preservation was published in 1969 (6).

Oaks for the Adelaide Plains: Successful Species in the Waite Arboretum
Treenet Proceedings of the 4 th National Street Tree Symposium: 4 th and 5 th September 2003 ISBN 0-9775084-3-9 Treenet Inc OAKS FOR THE ADELAIDE PLAINS: SUCCESSFUL SPECIES IN THE WAITE ARBORETUM Jennifer Gardner , Waite Arboretum, University of Adelaide, South Australia Abstract The University of Adelaide’s Waite Arboretum is a valuable experimental collection. Species of oaks performing well there under natural rainfall of 625 mm are reported. Most successful are the species from the Mediterranean region, California and Mexico. Many of these oaks have potential for street or amenity planting. Introduction Oaks belong to Quercus, one of eight genera in the family Fagaceae that occurs primarily in temperate Northern Hemisphere. The family also includes sweet chestnuts Castanea (8 spp.), Trigonobalanus (3 spp.), beeches Fagus (10 spp.), Chrysolepis (2 spp.) and two tropical genera Castanopsis (134 spp.) and Lithocarpus (325 spp.) (Govaerts & Frodin, 1998). In Australia the family is represented by the Gondwanan genus Nothofagus (34 spp.) which considered to be in a separate family by Hill & Jordan (1993). Of the 531 species of oaks, about 250 occur in the Americas, 125 in Asia and Malesia and the rest in Europe, N. Africa and Macaronesia (Govaerts & Frodin, 1998). Sierra Madre Occidental, Mexico and East and Southeastern Asia are rich in species. The infrageneric taxonomy of oaks is in a state of flux and various schemes exist. Oaks are widely cultivated, and widespread hybridisation and high variability make the delimitation of some species contentious. The Waite Arboretum The Waite Arboretum is nestled in the foothills of Adelaide, South Australia , 34 o58’S 138 o 38’E at an altitude of 100 – 110m.

MCMILLAN School of Agriculture, Forestry, and the Environment Clemson University Clemson, South Carolina 29634 CHRISTOPHER W. BLACKWELL Department of Classics Furman University Greenville, South Carolina 29613 ABSTRACT John Lawson, surveyor-general of Carolina, published a well-known travelogue and natural history called A New Voyage to Carolina in 1710. He also sent numerous herbarium specimens to James Petiver in London. Petiver’s collections ended up in Hans Sloane’s herbarium, where they are now part of the Sloane Herbarium in the Natural History Museum, London. We have digitally photographed these specimens and placed them online as part of the Botanica Caroliniana project. Here we present determination of the taxa in Lawson’s collections along with observations on Lawson’s movements and other work. John Lawson was one of the great early explorers of North America. Between 1700 and 1711 he visited and mapped a good portion of the colony then called Carolina, staying with Indians and watching his colleagues’ exploits with amusement. He turned this experience into both a good job –– surveyor-general of Carolina –– and a bestselling 1710 travel memoir, A New Voyage to Carolina . He even died a glamorous –– albeit unpleasant –– death, captured and executed by Indians.
