Abstract: This disclosure concerns a new and distinct variety of Acer saccharum (commonly known as sugar maple tree) characterized by its exceptional growth habit with thick, leathery leaves, a tight compact crown with a heavy distribution of leaves which are not subject to tatter, and its extreme ease of propagation.

Abstract: A new and distinct variety of a new cultivar of sugar hackberry tree characterized by a well balanced, spreading crown having more branches than other sugar hackberry trees in the stand, a fast growth habit, freedom from Witches Broom disease found in native hackberry trees in the same growing area, and its being very hardy even in temperatures below -20.degree. F.

Abstract: This disclosure concerns a new and distinct variety of Acer saccharum (commonly known as sugar maple tree) characterized by its exceptional growth habit with thick, leathery leaves, a tight, compact, oval shaped crown with a heavy distribution of leaves which are not subject to tatter, and its extreme ease of propagation.

Abstract: A new and distinct variety of cultivar of Ginkgo tree of the Ginkgo biloba type characterized by a more compact habit of growth and a more desirable arrangement of branches growing at a favorable angle from the trunk and the crown having a full, dense, moderate spread.

Abstract: This disclosure concerns a new and distinct variety of Grandiflora Amelanchier characterized by its exceptional vigorous growth habit with an abundance of pure white flowers in the spring, and thick, glossy leaves turning a brilliant red color in the fall of the year all substantially simultaneously.

Abstract: A new and distinctive variety of Fraxinus pennsylvanica lanceolata having shorter internodes, usually less than four inches long on first year stems, tighter crown being pyramidal symmetrical that maintains its shape, by leaflets of dark green above and silvery underneath, by a thicker bark on the trunk and by being disease and insect resistant.

Abstract: A silver linden tree having a compact form, relatively smooth bark, few flowers and fruits, and healthy foliage.

Abstract: A new Thornless Honeylocust being seedless and having a rapid rate of growth and dense crown.

Abstract: A new and novel Tilia cordata having exceptionally straight branches, a definite central leader; the tree assuming a more broadly pyramidal shape than other trees of the specie. Growth rate is exceptionally rapid. The fall foliage coloration is yellow.

Abstract: A unique Quercus robur denominated `Wandell`, characterized primarily by having an extremely fastigiate, upright, attractive appearance; resistance to powdery mildew; and, dense, concentrated and strongly ascending branching habit.

Abstract: A new variety of Acer rubrum of attractive, pyramidal growth habit, medium size, and early, uniform brilliant scarlet fall coloration. The tree has a full, dense and heavily leaved crown.

Abstract: A new and distinct Pyrus betulaefolia pear tree which is superior in mature leaf glossiness, coloration, a longer petiole and placement, when compared to other trees of the specie. The new trees named `Southworth` has strongly ascending branches which develop into a tree of symmetrical, ovoid crown.

Abstract: A male green ash tree having a strong central leader, strongly ascending uniformly spaced scaffold branches, uniform crotch angles, and heavy stems, forming an attractive, narrowly oval tree of compact appearance and low pruning requirements; further, the subject tree develops a heavy furrowed protective bark at an early age on the bole and branches progressing from smooth juvenile ash-gray bark slightly tinged with red. Fall foliage color is ephemeral turning to bronze-red with heavy autumn frosts.

Abstract: This new varietal sport of Fraxinus pennsylvanica summit green ash has been produced asexually from a sport branch of `Summit` green ash (Fraxinus pennsylvanica `Summit`) found growing on a tree at Madison, Wis. with the characteristic of many lateral branches growing from a main branch or limb axis. Propagation by me asexually from this sport produced vigorous straight-growing trees with a strong central leader, an adnormally high number of lateral branches, many appearing at three inch intervals on the main stem. These laterals grew in a strongly ascending manner producing semi-lustrous dark green foilage, turning yellow in the fall, and tree crown with a ratio of 15 to 20% of the height in width, much narrower than asexual progeny of Summit ash of the same age and size.

Abstract: This new variety of Acer.times.freemani was discovered in Urbana, Ill.; it shares some of the characteristics of both parent trees Acer rubrum and Acer saccharinum is a dense crown, heavy leaf population, substantial limb scaffold, rapid rate of growth, resistance to drought and winter crown damage, and a brilliant red fall color each October on all parts of the leaves on all ages of trees.

Abstract: This is a variety of Syringa pekinensis and has been reproduced asexually from a tree found growing at Milwaukee, Wisconsin with the characteristics of an upright growth habit of 12 feet wide and 18 feet tall without the benefit of cultural pruning and trimming. Propagated by me asexually it produced straight-growing progeny with a strong central leader; a tree crown producing an abundance of fine textured deep green leaves and large cream colored flower trusses annually. The bark is a lustrous reddish-brown with many very horizontal lenticels. Progeny produced show rapid and sustained growth.

Abstract: A new variety of Oak tree, which is named `Crimschmidt`, has a narrow fastigiate growth habit, a red fall color and demonstrated resistance to powdery mildew.

Abstract: This is a variety of Pyrus calleryana.times.betulifolia and has been reproduced asexually from a tree found growing in a cultivated area in Du Page County, Ill. with a growth habit of 20' wide and 25' tall without benefit of cultural pruning and trimming. When propagated by me asexually it produced straight-growing progeny with a strong central leader; a tree crown producing annually an abundance of substantially deep green leaves and flowers followed by small persistent fruit. The bark is gray-brown with reddish underbark with elongated scales broken by shallow longitudinal fissures.
