 with a transversal line and a little or not elevated 

 obtuse umbo: seed % in. long. Mediterranean region. 

 G. C. II. 22:553; III. 3:629.-Not hardy north and of little 

 ornamental value, but recommended for seaside plant- 

 ing. Trunk usually slender and destitute of branches 

 for a considerable height: foliage thin and sparse, in 

 tufts at the end of branchlets. Var. Pithyusa, Stev., is 

 a smaller tree with slenderer branches, longer Ivs. and 

 smaller cones. W. Asia.

 to 80 ft., with slender, spreading branches: branchlets 

 yellowish brown: Ivs. very slender and thin, light 

 green, 5-8 in. long: cones oblong-ovate or ovate, dull 

 brown, 2-3 in. long; apophysis flattened, slightly keeled, 

 with a small, flat, unarmed umbo: seed 1-5 in. long.

 founded with P. Thunbergi and P. densiflora. 



43. densiflora, Sieb. & Zucc. JAPANESE RED PINE. 

 Tree, to 100 ft., with spreading branches forming an 

 irregular, rather broad head : branchlets orange-yellow, 

 bloomy: buds oblong -ovate, chestnut -browns Ivs.

 the base sometimes elongated ; umbo small, with a short 

 prickle or obtuse: seed grayish yellow, % in. long. Jap. 

 S.Z. 2:112. Ornamental hardy tree, rapidly growing 

 when young, often very picturesque when older. Many 

 garden forms are cult, in Japan, several of them with 

 variegated Ivs. The best are perhaps var. aurea, Mayr, 

 with yellow foliage; var. albp-terminata, Mayr, with the 

 tips of the Ivs. yellowish white, and var. Oculus draconis, 

 Mayr, like var. variegata, Mayr, similar to the vars. of 

 the same name under P. Thunbergi.

 dark gray, 1-6 in. long. Eu. to W. and N. Asia. Gn. 36, 

 p. 167; 38, p. 455; 49, p. 296. -One of the most impor- 

 tant timber trees of Europe. It is quite hardy, but has 

 little to recommend it as an ornamental tree. Several 

 geographical and garden forms have been distinguished. 

 Var. argentea, Stev. Foliage light bluish green, with 

 silvery hue. Var. aurea, Hort., with the young Ivs. 

 golden yellow. Var. colunmaris compacta, Bailly.

 has been divided according to the cones into the follow- 

 ing 3 vars. or subspecies. Var. uncinata, Willk. (in- 

 cluding var. rostrdta arid rotunddta, Ant.). Cone very

 often reflexed umbo. Often arborescent. Var. Pumilio. 

 Willk. (P. Pumilio, Hsenke. P. Carpdtica, Hort.).
