ENUMERATION OF CONIFERS 221 



handsome Thuja-like tree of narrow-pyramidal or columnar habit with deep 

 green lustrous foliage, the upper branchlet-systems in vertical planes. A 

 few garden forms are cultivated in Europe. 



The following species are occasionally seen in European collections, but 

 are apparently unknown in American gardens; they are all tender and could 

 be grown only in the Southern States and California; L. chilensis may be 

 somewhat hardier than the others, 



L. chilensis, Endl. Chilean I. Tree to 60 feet tall, with compact pyram- 

 idal head; branchlets much compressed: facial leaves minute, obtuse, glandu- 

 lar, the lateral ones much larger, boat-shaped, keeled, acute and spreading 

 at apex, with a silvery line beneath: cones ovate-oblong, 3^ inch long. Chile. 

 — Introduced in 1847 to Great Britain. 



L. cupressoides, Sarg. (L. tetragona, Endl.). Tree to 100 feet tall, with 

 compact pyramidal head, sometimes shrubby; branchlets almost tetragonal: 

 leaves all alike, spreading, ovate or ovate-lanceolate, acute or obtuse, -^-^ inch 

 long: cones ovate; scales with a large curved spine on the back. Chile to 

 Patagonia. — Introduced in 1849 to Great Britain. 



L. macrolepis, Benth. & Hook. Tree to 100 feet tall; branchlets com- 

 pressed, glaucous below with white markings: leaves of equal length, acute, 

 the lateral strongly keeled, the facial ones obovate, apiculate: cones obovate- 

 oblong, about ^4 inch long, consisting of 6 truncate scales. Southwestern 

 China, Formosa. — Introduced to Great Britain in 1899. 



L. plumosa, Sarg. {L. Doniana, Endl.). Tree to 100 feet tall, with dense 

 pyramidal head; branchlets much compressed: facial leaves ovate, acute, 

 scarcely glandular, lateral leaves longer, spreading and acute at apex, with a 

 white band below: cone about ^2 "^ch long; scales 4, with a large curved spine 

 on the back. New Zealand.— Introduced to Great Britain in 1847. 



A related genus not in cultivation in this country is Fokienia; it is inter- 

 mediate in its characters between Chamsecyparis and Libocedrus, resembling 

 the latter in the foliage and in the seeds having -i very unequal lateral wings; 

 the cone is subglobose and composed of numerous peltate scales, each bearing 

 2 seeds. — Two species in southeastern China. F. Hodginsii, Henry & 

 Thomas (Cupressus Hodginsii, Dunn). Tree to 40 feet; brancldets much 

 flattened: the lateral leaves with spreading acute apex, green above and 

 with white markings below: cone 1 inch across, ripening the second year. — 

 Introduced into England in 1909 by Captain Hodgins. 



6. THUJA, L. ARBOR- VIT^ 



Evergreen aromatic trees with thin scaly bark and short branches; the 

 flattened branchlets arranged frond-like: leaves decussate, scale-like, ap- 

 pressed, usually glandular on the liack: flowers moncecious, globose, small,
