Fragaria collina, Ehrhart. 



Hill-Strawberry. In various parts of Europe. Cutivated in 

 Norway to lat. 67 56' (Schuebeler); may be regarded as a mere 

 variety of F. vesca. Fruit of a somewhat musky odor. 



Fragaria grandiflora, Ehrhart. (F. Ananas, Miller.) 



Ananas-Strawberry. Various colder parts of America. Closely 

 allied to F. Chiloensis. Many of the large-fruited varieties have been, 

 derived from this species. 



Fragaria Illinoensis, Prince. 



North-America. Hovey's seedling and the Boston-kind from 

 this plant. Is regarded by Professor Asa Gray as a variety of F. 

 Virginiana. 



Pragaria pratensis, Duchesne. (F. elatior, Ehrhart.) 



Cinnamon- Strawberry. Hautbois. In mountain-forests of Europe. 

 F. moschata (Duchesne) is a variety of this species. 



Fragaria vesca, Linne". 



Wild Wood- Strawberry. Naturally very widely dispersed over the 

 temperate and colder parts of the northern hemisphere, extending 

 northward to Lapland and Iceland, southward to the mountains of 

 Java, ascending the Himalayas to 13,000 feet (J. D. Hooker). From 

 this typical form probably some of the other Strawberries arose. 

 Middle forms and numerous varieties now in culture were produced by 

 hybridization. These plants, though already abounding in our gardens, 

 are mentioned here, because they should be naturalized in any ranges. 

 Settlers, living near some brook or rivulet, might readily set out 

 plants, which, with others similarly adapted, would gradually spread 

 with the current. The minute seeds will retain their vitality for fully 

 three years. A highland-variety, F. alpina (Persoon), furnishes fruit 

 throughout the warm season, long after the other varieties cease 

 bearing in gardens (Vilmorin). 



Pragaria Virginiana, Miller. 



Scarlet Strawberry. Eastern North-America, extending northward 

 to 64 (Sir J. Richardson), therefore adapted for the coldest climates 

 also, yet even fruiting well in Bermuda (Sir J. Lefroy). 



Fraxinus Americana, Lhme".* 



The White Ash. Eastern North- America, extending from Florida 

 to Canada. A large tree, which delights in humid forests. Trunks 

 have been found 75 feet long without a limb, and 6 feet in diameter 

 (Emerson). It is the best of all American Ashes, and of compara- 

 tively rapid growth. In Nebraska the stem attains to about 32 inches 

 circumference at 2 feet from the base in 22 years (Furnas). Resisting 

 extreme heat better than the common Ash. Timber largely exported ; 

 it assumes a red tint in age ; much valued for its toughness, lightness 

 and elasticity, excellent for work subject to sudden shocks and strains,
