92 PRACTICAL FORESTRY. 



their distribution, not only among different trees growing under 

 exactly the same conditions, but on different parts of the same 

 tree. Sometimes the leaves on a single branch will change to 

 an intense crimson or scarlet, while those on other branches wiU 

 retain their normal color until cut by frosts. Then, again, one 

 tree in a row will assume the scarlet or crimson color, and those 

 adjoining will show very little, if any coloring, except perhaps 

 a faded red or yellow ; but the veiy next season these colors 

 may be reversed. 



The Red Maple is not only a handsome tree, but well worth 

 cultivating, both for ornamental and useful pui-poses. There 

 are several varieties in cultivation, but not sufficiently distinct 

 as to have attracted much attention. Acer rubrum fulgens is a 

 dwarf variety, and A. r. globosum is a variety with a globose, or 

 round head, while A. r. pyramidalis is a very distinct i^yrami- 

 dal form. 



A. Spicatnni. — Mountain Maple. — Leaves slightly three-lobed; 

 coarsely toothed ; downy beneath, with dense, upright racemes 

 of flowers appearing very late in the spring, succeeded by small 

 seeds with narrow wings. It is only a small shrub, six to ten 

 feet high, found in the Northern Border States and on some of 

 the higher mountains southward. 



A. PennsylTanicnui. — Striped-bark Maple, Moose-wood, Striped 

 Dog-wood. — Leaves large, thin, somewhat heart-shaped, but 

 with three-pointed, serrated lobes. Flowers greenish, in tenni- 

 nal racemes, appearing after the leaves. Seeds with large, diver- 

 gent wings. A small tree, with light-green bark, striped with 

 darker lines. Sometimes cultivated as an ornamental shrub or 

 small tree. 



A. (irdnatam. — Round-leaved, or Vine Maple. — Leaves rounded; 

 seven to nine lobes ; serrate. Flowers purplish, in small clus- 

 ters. The wings of the seed diverging in a straight line. A taU 

 shrub, but in some situations reaching a bight of thirty to forty 

 feet. A native of Northern California, and northward to 

 British Columbia. Wood very hard and fine-grained, but not 

 plentiful enough of large size to be worthy of much attention. 



A. macropiiyllnni. — Large-leaved Maple, California Maple. — 

 Leaves very large, deeply five to seven-lobed, with very coarse 

 teeth. Flowers of a yellowish color, in a compact raceme. 

 Fruit haiiy, with large, broad wings. A very large tree, 

 sometimes one hundred feet high, with stem five feet or more
