200 THE CULTIVATED EVERGREENS 



Var. Wilsonii, Rehd. Wilson J. Upright shrub to 6 feet, densely 

 clothed with short branchlets recurved at the tips : leaves shorter and broader, 

 crowded, broadly lanceolate, about }/q inch long. Western China. — Intro- 

 duced to the Arnold Arboretum by E. H. Wilson in 1909. 



Var. Meyeri, Rehd. Meyer J. Upright shrub much branched with 

 short, straight branclilets : leaves narrow-lanceolate, straight, }/i-\^ inch long, 

 very glaucous on back. China. — Introduced in 1914 by F. N. Meyer through 

 the Department of Agriculture. Very handsome on accoimt of its dense 

 habit and the bluish-white color of its foliage. 



A closely related species is J. recurva, Ham. A small tree to 30 feet tall, 

 with spreading, curved branches and pendulous branclilets: leaves very 

 concave above, grooved beneath below the middle: fruit ovoid, }/^-}/2 inch 

 long. Himalayas. — Introduced about 1830 to Great Britain. A graceful 

 tree, hardy probably only in the Southern States. 



8. J. procumbens, Sieb. (J. chinensis var. procumbens, Endl.). Low 

 spreading shrub with stiff ascending branclilets, about 2 feet high: leaves in 

 3's, linear-lanceolate, spiny-pointed, concave above and glaucous with a 

 green midrib toward the apex, below bluish with 2 white spots near the base 

 from which 2 glaucous lines run down the edges of the pulvini, }/i-}/i inch 

 long: fruit subglobose, 2-3-seeded, about f inch across. — Cultivated in 

 Japan and introduced in 1843 to Europe and in 1862 to America. Hardy as 

 far north as Massachusetts; sometimes planted as ground-cover, particularly 

 in California. 



9. J. pachyphloea, Torn (Sabina pachyphloea. Ant.). Alligator J. Tree

 ellipsoidal, tuberculate, reddish-brown, bloomy, about 3^ inch long, with 

 3-4 seeds. Arizona and New Mexico to southwestern Texas and Mexico. — 

 Introduced to Europe before 1875. One of the handsomest of the American 

 junipers, remarkable for its checkered bark; the acicular foliage of young 

 plants is usually glaucous to nearly silvery-white. Not hardy north of the 

 Middle Atlantic States.
