 Very variable in habit: the staminate plant usually 

 forms a much-branched, upright, pyramidal bush, 

 often almost columnar, while the pistillate has slender, 

 spreading branches. They are therefore often dis- 

 tinguished as var. mascula and var. femina (var. 

 Reevesii, Hort.). The first one is the most desirable as 

 an ornamental plant. Var. albo-variegata, Beissn. 

 (var. argentea, Hort.). Dwarf, dense form, with 

 dimorphic lvs. : tips of branchlets mostly white. Gn.M. 

 6:292. Var. a&rea, Beissn. (var. mascula aiirea, Hort.). 

 Upright form, with the young branchlets golden yellow, 

 the color becoming more brilliant in the full sun. Var. 

 pendula, Hort. With spreading branches, pendulous 

 at the extremities. Var. Pfitzeriana, Spaeth. Forming 

 a broad pyramid with horizontally spreading branches 

 and nodding branchlets, grayish green. G.W. 5, p. 403. 

 Var. pyramidalis, Carr. Narrow, pyramidal form, with 

 bluish green, mostly needle-shaped foUage. Var. 

 procumbens, End!. (J. prociimbens, Sieb. J. japdnica, 

 Carr.). Dense, low shrub with spreading, sometimes 

 procumbent branches and mostly acicular lvs. in whorls, 

 with 2 white lines above, longer and stouter than in 

 the type. S.Z. 127, fig. 3. G.W. 13, p. 618. Var. 

 procumbens afirea, Beissn. Branches robust and long, 

 decumbent, with rather few branchlets, young growth 

 golden yellow at first, changing to light green. Var. 

 prociimbens a&reo-variegata, Beissn. Dwarf, dense 

 form, variegated with golden yellow. 



15. sphierica, Lindl. {J. Fdrtunei, Van Houtte^lt,^ 

 Similar to the former. Densely branched shrub or tree, 

 to 30 ft., with upright branches: branchlets short, 

 rather thick, quadrangular: lvs. acicular and whorled, 

 but less rigid than those of the former, or scale-like, 

 rhombic-oblong, somewhat spreading: fr. globular, 

 about J^sin. across, not bloomy, 3-seeded. N. China. 

 Probably not specifically different from the preceding 

 species. Var. gla&ca, Gord. (J. Shephardii, Hort.). 

 Dense form, with usually needle-shaped glaucous 

 fohage.

 a. Trees hardy, sometimes shrubby. 



16. virgmiana, Linn. Red Cedar. Savin. Fig. 2025. 

 Tree, to 100 ft., with conical head and spreading or up- 

 right branches: lvs. acicular, spiny-pointed, spreading 

 or scale-hke, rhombic, acute or subacute, imbricate, 

 very small: fr^hrownish violet, bloomy, globular or 

 ovoid. CanaHa'to Fla., east of the Rocky Mts. S.S.

 540.^A very variable species. Some of the most 

 important varieties are the following: Var. albo-spi- 

 cata, Beissn. Tips of branchlets white. Var. albo-varie- 

 gata, Beissn. Branchlets variegated with white; 

 a very similar more constant form is "Triomphe d' 

 Angers." Var. afireo-variegata, Hort. With golden 

 yellow variegation. Var. Cannartii, Beissn. A com- 

 pact, ovate-pjTamidal form, dark green, with bloomy 

 bluish fr. Var. Chamberlaynii, Carr. With spreading 

 branches and elongated, pendulous branchlets: lvs. 

 dimorphic, grayish green. Var. dumosa, Carr. Dense 

 shrub, forming a rounded pyramid, with mostly needle- 

 shaped, bright green lvs. Var. elegantissima, Hort. 

 Tips of young branchlets golden yellow. ^ j.: . giauca, 

 Carr. Vigorous-growing form, with glaucous fohage. 

 Var. globdsa, Beissn. Compact globose form with 

 bright green scale-like foliage. Var. pendula, Carr. 

 With spreading limbs and sler .or, pendulous branches: 

 lvs. usually scaie-like. Var plumdsa, Hort. A graceful 

 pyramidal form with neef'-.e-shaped lvs., the tips whitish 

 (var. plumdsa alba or plumdsa argentea, Hort.), or pure 

 white (var. plumdsa ivea, Schwendt.). Var. pyram- 

 idalis, Carr. Deii"_, columnar form, with the foliage 

 glaucous (var " iramiddlis giauca) or bright green (var.
