16 FOREST-TREES OF THE UNITED STATES. 



ARALIACEJE. 



No. 147. Aralia spinosa, L. Angelica Tree or Hercules's Club. East- 

 ern United States. 



CORNACEvE. 



No. 148. Cornus florida, L. Flowering Dogwood.. Eastern United 

 States. This is usually a small tree, but sometimes acquires a height of 

 40 or 50 feet, and a diameter of trunk of li feet. It flowers in spring 

 before the full development of the leaves, and then presents a beautiful 

 appearance. It deserves to be more generally cultivated. 



No. 149. Cornus Nuttallii, Aud. White Dogwood. California and 

 Oregon. This species, which is confined to the Pacific coast, has rather 

 larger flowers than the preceding, and is perhaps more showy. The 

 wood of both is hard and valuable. Grows sometimes 50 or 60 feet high. 



No. 150. Cornus pubescens, Nutt. Western Dogwood. California and 

 Oregon. This rarely becomes a small tree, 25 to 30 feet high, on the Pa- 

 cific coast. We have five or six other species of dogwood which do not 

 attain tree size. 



No. 151. Garry a Fremontii, Torr. Tassel- tree. Oregon and Califor- 

 nia. The Garryas are mostly shrubs, though under favorable circum- 

 stances the Garry a elliptica gains a height of 20 to 30 feet. 



No. 152. Garrya elliptica, Lindl. Satin Tassel-tree. California. 



No. 153. Nyssa multiflora, Wang. Black or Sour Gum ; Pepperidge. 

 Eastern United States. A middle-sized tree, growing from Massachu- 

 setts to Illinois and southward. The fibers of the wood are so inter- 

 woven that it is almost impossible to split it; hence it is used for wheel- 

 hubs, rollers, and cylinders. (Bryant.) It is quite ornamental in cul- 

 tivation. 



No. 154. Nyssa aquatica, L. Water Tupelo. Southern States. This 

 species grows in low wet ground, chiefly in the Southern States, but is 

 found also in New Jersey and Pennsylvania. The wood is very tough, 

 and has been used in the manufacture of wooden bowls, &c. 



No. 155. Nyssa uniflora^ Walt. Large Tupelo. Virginia and south- 

 ward. This is the largest tree of the genus. It is confined to the South- 

 ern States, growing in swamps. It bears a dark-blue plum-like fruit 

 nearly an inch long. The wood is soft and extremely light. The roots 

 are also extremely light and soft, and have been used as a substitute for 

 cork. The wood is only used to make bowls and trays. 



No. 156. Nyssa capitata, Walt. Ogeechee Lime. Southern United 

 States. This species is found in swamps in Georgia and Florida and 

 westward near the coast. It bears an oblong red plum-like fruit, which 

 is agreeably acid, and can be employed as a substitute for the lemon. 

 The tree is small and the wood without value. 



CAPRIFOLIACE^E. 



No. 157. Sambucus ylauca, Nutt. California Elder. California and 

 Rocky Mountains. This species ot elder in California forms a low tree, 

 sometimes 30 feet high, with a stem 2 feet in diameter. Indians and 

 birds eat the berries. 



No. 158. Viburnum prunifolium, L. Black Haw. Eastern United 

 States. The haws are small trees or large shrubs, with smooth glossy 

 leaves and handsome flowers. They are worthy of cultivation. 



No. 159. Viburnum Lentago, L. Sweet Viburnum or Sheepberry. 

 Eastern United States. 



No. 160. Viburnum obovatum, Walt. Wild Haw. Virginia and south-
