specimen, though it breaks down in winter storms. At its best it has a some- 

 what freakish, exotic look. At one time a large number of seedlings of this 

 Wier cutleaf maple were grown here and but a small percentage showed 

 good cutleaf cliaracters. The seedlings varied widely in all respects. 



Acer (jinnala, Amur Maple. This ought to be a very hardy si)ecies, but 

 it has not proved so on the campus. If it were hardy and reliable it would 

 be a good small tree or large shrub and could be recommended for shearing 

 into hedges. 



Acer japonicum, Fullmoox Maple. A few specimens of this .Japanese 

 maple have been growing on the grounds for forty years or more. Of nmch 

 the same habit of growth as Acer palmatum varieties and may be treated 

 like them in a planting. 



Acer mit/abel, Miyabe Maple. A medium-sized tree, from Japan, attain- 

 ing to thirty-five feet. Branches abimdantly from a short trunk, producing 

 a large and rather open crown. Leaves much the same pattern as A. camp- 

 estre but larger and very dark green. Suitable for mass plantings in parks 

 or otiier large areas. 



Acer negundo, Boxelder. Small hardy tree or large shrub of no special 

 value. May be used in masses where foliage of coarse texture is desired. 

 Good for low windbreaks. 



Japanese Maple: 



Acer palmatum (itroltneare Bloodveix Maple. 



Acer jKihuitiuni d'atxectum Threadleaf Maple 



Acer palmaturii oriiutum Spiderleaf Maple 



Acer palmatum ruhrum Red Japaxese Maple 



Acer palmatum sanguineum Scarlet Japanese Maple 



Acer palmatum septemlohum Seveni.obe Maple 

 All these varieties of Japanese Maples have been tested. Most of tliem have 

 been growing on the college grounds for forty or fifty years. They are hardy 

 and quite satisfactory, making strong specimens usually ten to fifteen feet 

 tall and about the same diameter. Tlieir bright colors make them conspicu- 

 ous so that it would be possible to overemjiliasize them in naturalistic plant- 

 ing. For those who want sometliing sh(i\\y and out of the ordinary tiiese 

 maples would serve admirably. 



Acer peiinsylvanicum, Striped Maple. A liardy nati\e species common in 

 cold, shady woods; suitable for highly naturalistic underplanting, but not 

 a\ailable as an "onian'.ental" in the accepted sense of the term. 



.Irtr jilataiKiidcs, XoinvAv Maple. A gotd liardy ornan.ental tree, witli 

 stiff trunk and branches, thick, heavy dark foliage; good for street plant- 

 ing and for specimens, especially in crowded city conditions; a good shade 

 tree for park plantings.- An odd variety, tlie Crl^ipeu Norway Maplf (-•/. 

 platanoides cucullatum) has been growing on the grounds for forty years, 

 but has no value except as a curiosity. 



Acer phttiuioidcn ruhrum. Buoadleaf Norway Maple. A red-leafed variety 

 of tiie foregoing, iwteresting only as a rare specimen. 



Acer platanoides schwedleri, Schwedler Maple. A rather popular nursery 

 variety of the Norway maple notable for its very dark red foliage in early 

 spring, which turns a ricli dark color again in the fall. The best tree of this 

 sort, bvit too outsjioken for modest company.
