ENUMERATION OF CONIFERS 285 



in 1910 by E. H. Wilson to the Arnold Arboretum where it has proved hardy. 

 The fruiting tree will prove certainly very ornamental with its numerous 

 purple cones. 



A closely related species is P. likiangensis, Pritz. Tree to 100 feet tall; 

 branchlets pale yellow, pubescent, with spreading petioles about -^ inch long: 

 leaves acute or mucronate, beneath with 1 or 2 often incomplete rows of 

 stomata on each side: cone cylindric-oblong, about 3I2 inches long, with 

 rhombic-ovate thin scales denticulate and nearly rounded at apex. Western 

 China. — Introduced to Europe between 1900 and 1910. The related P. 

 hirtella, Rehd. & Wils., is not in cultivation. 



25. P. jezoensis, Maxim. (P. ajanensis, Fisch. Abies jezoensis, Sieb. & 

 Zucc. Abies Alcockiana, Veitch, partly). Yeddo S. Tree 100-150 feet tall 

 or occasionally higher, with horizontally spreading slender branches; bark 

 dark gray, scaly, deeply fissured in old trees; branchlets glabrous, shining, 

 yellowish-brown or yellowish-green, the leaf-cushions slightly swollen, with 

 usually recurved petioles; winter-buds conical, resinous, lustrous: leaves 

 compressed, slightly curved, acute, slender, slightly ridged on both sides, 

 dark green and shining below, silvery-white above, J^-^ inch long : flowers 

 carmine: cones oblong, light brown, \}/2-^Y2 inches long; scales thin and 

 flexible, oval-oblong, erose. Northeastern Asia to northern Japan. — Intro- 

 duced in 1878 by Charles Maries. 



Var. hondoensis, Rehd. (P. hondoensis, Mayr. P. ajanensis var. viicro- 

 sperma, Beiss., not Mast.). Hondo S. Tree to 100 feet tall; branchlets light 

 reddish-brown with much swollen leaf -cushions : leaves shorter, more obtuse, 

 dull green below. Central Japan. — Introduced to England by Veitch in 

 1860. It is hardy as far north as Massachusetts and is a handsome orna- 

 mental tree of broad-pyramidal habit and bright green dense foliage. The 

 typical form is rarely cultivated and is not doing well in the eastern States; 

 it is of thinner habit and is liable to suffer from late frosts on account of its 

 early leafing. 



A hybrid between P. jezoensis and P. mariana is P. Moseri, Mast. 

 Branchlets smooth, olive-brown: leaves quadrangular, acute, H-^ inch 

 long, slightly compressed, glaucous above, green beneath. Originated in 

 France sometime before 1900. 



26. P. sitchensis, Carr. (P. sitkaensis, Mayr. Abies Menziesii, Lindl.). 

 Sitka S. (Tideland S.). Tree usually 100, occasionally 200 feet high, with, 

 slender horizontal branches, forming a broad pyramid in young trees; in 

 old trees the upper branches short and ascending, the lower ones slender and 

 spreading, clothed with slender branchlets; bark bright or dark red-brown; 

 branchlets rigid, light brownish-yellow, glabrous; winter-buds conical, 

 acutish, light brown, resinous, the terminal bud at base with a few acuminate 

 scales: leaves bright green, shining and rounded on the lower side, flat.
