Native Plants of East Central Illinois and Their Preferred Locations”
OCTOBER 2007 Native Plants at the University of Illinois at Urbana-Champaign Campus: A Sourcebook for Landscape Architects and Contractors James Wescoat and Florrie Wescoat with Yung-Ching Lin Champaign, IL October 2007 Based on “Native Plants of East Central Illinois and their Preferred Locations” An Inventory Prepared by Dr. John Taft, Illinois Natural History Survey, for the UIUC Sustainable Campus Landscape Subcommittee - 1- 1. Native Plants and Plantings on the UIUC Campus This sourcebook was compiled for landscape architects working on projects at the University of Illinois at Urbana-Champaign campus and the greater headwaters area of east central Illinois.1 It is written as a document that can be distributed to persons who may be unfamiliar with the local flora and vegetation, but its detailed species lists and hotlinks should be useful for seasoned Illinois campus designers as well. Landscape architects increasingly seek to incorporate native plants and plantings in campus designs, along with plantings that include adapted and acclimatized species from other regions. The term “native plants” raises a host of fascinating scientific, aesthetic, and practical questions. What plants are native to East Central Illinois? What habitats do they occupy? What communities do they form? What are their ecological relationships, aesthetic characteristics, and practical limitations? As university campuses begin to incorporate increasing numbers of native species and areas of native planting, these questions will become increasingly important. We offer preliminary answers to these questions, and a suite of electronic linkages to databases that provide a wealth of information for addressing more detailed issues. We begin with a brief introduction to the importance of native plants in the campus environment, and the challenges of using them effectively, followed by a description of the database, online resources, and references included below. -

Foundation Arboretum Wespelaar Year Report 2019
Foundation Arboretum Wespelaar Year Report 2019 2019 started with an early spring: by mid-March the early magnolias were in full flower. Temperatures kept rising and the heat record was broken in July, making the summer of 2019 one to be recorded in history books. Luckily, small rain showers and increased irrigation capacities ensured that we lost very few plants. In March 2019, the construction of the Artois Pavilion started in the Artois Meadow, at the end of two important vistas. The design is inspired by the old pavilion along the canal in the Park of Wespelaar. In the new Arboretum de Marche, a total of 189 trees have been planted in the past two years. In collaboration with Natagora, five ponds were created and a 5ha plot was sown with wild seed to create a meadow of native grasses and flowers. The building permit for the visitors centre and technical facilities was obtained. 2019 was a very active year for both Arboretum Wespelaar and Arboretum de Marche, as is described in more detail in this Year Report. Arboretum Wespelaar – Year Report 2019 1 THE COLLECTIONS ‘Patty’ can be planted in the Arboretum in due time. The living collection of woody plants in the Arboretum currently (as of 30 January 2019) Once again, our winter was not worth contains 5,116 specimens representing 2,340 mentioning and by mid-March we could have different taxa (versus 16,376 specimens and opened the Arboretum for our visitors because 4,955 taxa on the whole of the estate).

ARNOLD ARBORETUM BULLETIN POPULAR I~I~'C~~~~A't'ic~I~1
NEW SERIES VOL. IX N0.77 ARNOLD ARBORETUM HARVARD UNIVERSITY BULLETIN OF POPULAR I~i~’C~~~~A’T’IC~I~1 JAMAICA PLAIN, MASS. MAY 28, 1923 American Crab Apples. Among the small North American trees still imperfectly known to botanists and wood-lovers and scarcely known at all to gardeners are the different species, varieties and hybrids of the Wild Apple. Nine species of these trees are now recognized, with several varieties, and two hybrids and their varieties. They have white or pink fragrant flowers which do not open until the leaves are partly or entirely grown, and green or pale yellow fragrant fruit which hangs on slender stems and, with the exception of that of the species from the northwestern part of the country is depressed-globose, usually from an inch to two and a half inches in diameter and covered with a waxy secretion. All the species spread into thickets and are excel- lent plants for the decoration of wood-borders and glades. Some of the species have only been distinguished in recent years, and although the species and many of the varieties a~°e now growing in the Arbore- tum several of these have not yet flowered; only two or three of these Crab Apples can be found in commercial nurseries. Malus glauceseens, which is named from the pale glaucous color of the under surface of the leaves, is the first of the American species to flower here and has been blooming for more than a week. It is a shrub usually rather than a tree, not more than fifteen feet high, with stems four or five inches in diameter. -

Grows vertically with a straight main trunk. The winter buds are a remarkable brownish-red colour and glossy. In the spring the young leaves emerge almost white. Once they are fully grown only the underside remains a remarkable light grey. The leaves are rough and slightly lobed. No other ornamental apple tree has such exceptional autumnal colours as this. With its many shades, from purple and copper through orange to yellow, the tree is a real eye-catcher in the autumn. The (fragrant) flowers and the fruits are much less spectacular than those of the other ornamental apple trees. -

A total of 119 Horticulture and Forestry, decamer primers were initially screened to check these biotypes during the genotypic screening out of Nauni, Solan, Himachal which 94 showed clear and scorable bands. In samples collected from IARI Regional Station, Shimla, Pradesh, India these primers revealed 67.47% of polymorphism and PIC value ranged between 0.497 to 0.867, whereas average number of alleles per primer was 4.84. Jaccard’s similarity coefficient ranged from 0.44 to 0.65 which showed the divergence among the biotypes. Comparatively low percentage polymorphism (53.37%) was observed in seven biotypes maintained at NBPGR, Regional Station, Shimla, while almost similar PIC value range 0.47-0.87 was obtained as in case of former. -
Japanese Apple Rust Gymnosporangium Yamadae Belongs to the Pucciniales, an Order That Includes Rust Fungi That Cause Diseases on Plants
U.S. Department of Agriculture, Agricultural Research Service Systematic Mycology and Microbiology Laboratory - Invasive Fungi Fact Sheets Japanese apple rust Gymnosporangium yamadae belongs to the Pucciniales, an order that includes rust fungi that cause diseases on plants. Gymnosporangium yamadae has been limited in distribution to Asia (China, Japan and Korea) where it can be a serious pathogen of cultivated apples, especially if the host of the telial state, Juniperus spp., occurs in close proximity. This fungus was recently reported from the United States (DE, PA) in its aecial state on the ornamental tree, Malus toringo (Yun et al. 2009). Gymnosporangium yamadae Miyabe ex G. Yamada 1904 Aecia on Malus, foliicolous, then hypophyllous, also less commonly caulicolous, fructicolous; initially developing in a whitish leaf spot that becomes rose red with a distinct margin. Peridium cornute to tubular, 3-7(-8) mm high, retaining this shape at maturity but with lacerate sides that often form a reticulate pattern, apex typically closed to occasionally dehiscent, yellow-brown to brown; peridial cells long-narrow rhomboid to linear-rhomboid, 59-115 µm long, pale yellow, appearing verrucose with long papillae to tuberculate, outer walls smooth, inner and side walls sparsely echinulate. Aeciospores globoid, 16-26 × 18-27 µm, walls dark yellow, 1.0-2.5 µm thick, rarely up to 3.5 µm thick, sparsely echinulate, 4-7 pores scattered on surface. Telia on Juniperus, caulicolous, rarely foliicolous, produced on globoid swellings or small galls, telial horns cylindric-acuminate, 1-3 mm diam, 5-8 mm high or more, orange, gelatinouse. Teliospores two-celled, oblong, ellipsoid or obovoid, 15-28 x 32-56 µm, walls 0.8-2.0 µm thick, yellow or orange, with two pores near septum and one pore toward apex in upper cell, frequently with an obtuse, hyaline papilla at apex. -
Crabapple Malus
Crabapple Malus Throughout the winter, many cultivars of crabapple trees including Malus x 'Red Jade' and Malus x 'Prairiefire’ can be easily identified by their branches bursting with small, bright red fruit. Beside adding color to a stark landscape, the fruit provides an important source of food to birds. When they bloom in late April or early May, crabapples are a crucial species for pollinators, as their early blossoms and month-long flowering season help to sustain bees. When they are in bloom, crabapple trees are effective for pollinating any variety of apple tree within fifty feet. In fact, orchardists used to take their blossoming branches and put them in a bucket of water in the middle of their apple orchards so that bees would visit the crabapple blossoms and then visit the apple blossoms as they opened on the apple trees, improving the fruit set. There are numerous species with the genus Malus, and not all of them have winter fruit. The definition encompasses all wild apples, which are much smaller than those grown commercially and named based on their pinching, sour taste. While wild apples are believed to have originated in Kazakhstan and then spread throughout the Mediterranean and Europe, there are a number of varieties indigenous to North America, including malus angustifolia (narrow-leafed crab apple), malus coronaria (prairie crab apple), and malus ioensis (Iowa crab apple). These were particularly beloved by Henry David Thoreau, who wrote at length about them in his 1862 essay Wild Apples, noting that some fruits were “sour enough to set a squirrel's teeth on edge and make a jay scream.” While some fruits are incredibly tart, they are not toxic aside from the seeds.
