ENUMERATION OF CONIFERS ^55 



lustrous, yellowish-gray: leaves spreading at nearly right angles on the 

 middle ranks and partly more or less recurved, pectinate below, linear, 

 I -13^2 inches long, shorter on fertile branches, acutish or sharply pointed, 

 lustrous or bluish-green above, paler green beneath: cones oblong-ovoid, 

 2-4 inches long, violet-purple before maturity, finally grayish-brown; scales 

 about I inch wide; bracts hidden. Western China. — Introduced in 1910 

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

 handsome fir, very distinct on account of the partly recurved spiny leaves. 



12. A. holophylla, Maxim. Needle F. Tree to 100 feet tall; winter-buds 

 slightly resinous; branchlets yellowish-gray, glabrous, slightly grooved: 

 leaves spreading at nearly right angles outward and upward, pectinate 

 below, linear, entire at apex and spiny-pointed in young plants, acute or 

 obtusish in older trees, lustrous bright green above, with grayish or slightly 

 whitish bands beneath: cone cylindric, 5-6 inches long, green when young, 

 finally dull light brown; scales lJ^-2 inches wide; bracts hidden. Manchuria 

 and Korea. — Introduced in 1905 to the Arnold Arboretum where it has 

 proved hardy and promises to become a handsome and distinct tree of 

 pyramidal habit with bright green lustrous foliage. 



13. A. finna, Sieb. & Zucc. (A. bifida, Sieb. & Zucc. A. Momi, Sieb.). 

 MoMi F. Tree to 120 feet tall; bark dark gray, soon becoming scaly, fissured 

 on old trees; buds small, slightly resinous; branchlets brownish, slightly 

 grooved, short-pubescent in the grooves: leaves pectinate, linear, broadest 

 about the middle, with bifid pungent apex on young plants, obtuse and 

 emarginate on older plants, up to 13^ inches long, lustrous dark green above, 

 not keeled and with grayish bands beneath :. cone cylindric, gradually nar- 

 rowed toward the apex, 4-5 inches long, yellowish-green before maturity; 

 bracts exserted, not reflexed. Japan. — Introduced to Great Britain in 1861 

 by J. G. Veitch and the following year by Dr. G. R. Hall to this country. 

 It is hardy as far north as New York and can be grown in sheltered positions 

 in eastern Massachusetts. It is not doing as well as the other Japanese 

 firs in the Eastern States, and is likely to become a thin, rather scraggy tree 

 when older. 



14. A. homolepis, Sieb. & Zucc. {A. hrachyphylla, Maxim.). Nikko 

 F. Fig. 06 and Plate XXV. Tree to 120 feet tall; bark scaly; winter-buds 

 ovoid, resinous; branchlets deeply grooved, particularly on two- and three- 

 year-old branchlets, grayish, glabrous: leaves spreading outward and upward, 

 separated in the middle by a V-shaped depression, pectinate below, those of 

 the outer ranks about 1 inch long, of the middle ranks shorter, linear, rounded 

 and slightly bifid at apex, shining dark green above, with broad white bands 

 beneath: cones cylindric, slightly narrowed at the ends, about 4 inches long, 

 purple before maturity; scales about f inch wide, entire at the margin; bracts 

 hidden. Japan. — Introduced in 1861 to Great Britain by J. G. Veitch.
