202 THE CULTIVATED EVERGREENS 



and rounded on back and conspicuously glandular, grayish-green; acicular 

 leaves in 3's, often Yl inch long, inconspicuously glandular: fruit globose or 

 ovoid, H-M inch long, dark blue, bloomy, 1-seeded, rarely 2-3-seeded; the 

 seeds sometimes exserted, pale chestnut-brown, obtuse and prominently 

 ridged. Colorado to Nevada, western Texas and northern Mexico. — Intro- 

 duced about 1900 to Germany. Of little ornamental value and probably not 

 hardy north of the Middle Atlantic States. 



A related species is !• mexicana, Schlecht. (J. sabinoides, Nees. J. tetra- 

 gona, Schlecht.). Tree to 30 or occasionally to 100 feet tall: leaves obtuse or 

 acute, thickened and keeled on back, usually eglandular: fruit M-H inch 

 long; seed ovoid, acute, slightly ridged. Western and southern Texas to 

 central Mexico. — Introduced to Europe in 1841; hardy only in the Southern 

 States. 



Also the following species, not or scarcely known in this coimtry, belong 

 to this affinity, having dark blue fruit and ciliolate leaves: 



J. Wallichiana, Hook. Tree to 60 feet tall, with spreading branches, or 

 shrub; branchlets slender: scale-like leaves free at the acute tips, bright 

 green, furrowed and glandular on back; acicular leaves in 3's: flowers dioe- 

 cious: fruit upright, ovoid, about 3^ inch long, 1-seeded, Himalayas. — 

 Introduced to England in 1849. 



J. pseudosabina, Fisch. & Mey. Low shrub closely related to the pre- 

 ceding, but leaves less acute and fruit smaller, recurved, often globose. 

 Altai Mountains, Turkestan. — Introduced some time before 1900. Hardy 

 north. 



J. saltuaria, Rehd. & Wils. Tree to 50 feet tall: leaves bright green, 

 closely appressed, slightly incurved at the acute or obtusish apex, slightly 

 glandular: flowers monoecious: fruit erect, subglobose or ovoid, about 3<^ 

 inch long, black, not bloomy, 1-seeded. Western China. — Introduced in 

 1904. 



J. thurifera, L. (J. sabinoides, Griseb., in part. Sabina thurifera. Ant.). 

 Tree to 40 feet, usually narrow-pyramidal in cultivation ; branchlets pinnately 

 ramified, slender: leaves scale-like, free at the acuminate apex, glandular, 

 like the acicular ones opposite: fruit subglobose, about }4 inch across, 2-4- 

 seeded. Southwestern Europe, northern Africa. — Introduced before 1750 

 to Great Britain. This differs from all the preceding species of the section 

 Sabina in having also the acicular leaves opposite and from No. 12 and the 

 four preceding species in the 2-4-seeded fruit. 



13. J. excelsa, Bieb. Greek J. Pyramidal tree to 60 feet tall, with upright 

 or spreading branches: leaves usually scale-like, on smaller branchlets op- 

 posite, closely appressed, rhombic-ovate, with incurved acute apex, glandular 

 on back, dark or bluish-green, on leading shoots usually in 3's, acute, free at 

 apex; acicular leaves opposite, with 2 glaucous bands above, -g-y^ inch long:
