Trees of Great Britain and Ireland, Vol. II. p. 202 (1907). 



A tree attaining in Japan a height of 40 to 100 feet, with reddish 

 bark scaling off in longitudinal shreds. Branches in false whorls or 

 scattered, giving off secondary branches, which terminate in flattened, 

 frondose, tripinnate branchlet-systems disposed in horizontal planes. 



Leaves persisting several years, in four ranks, in decussate pairs, 

 coriaceous ; ventral and dorsal leaves flattened, ovate or spathulate ; 

 lateral leaves carinate, more or less spreading, with an acute in- 

 curved apex ; foliage green on the upper side of the branchlets, 

 with conspicuous white stomatic depressions below. 



Flowers monoecious ; the staminate flowers on separate lateral 

 branchlets, cylindric, \ inch long, with six decussate pairs of sta- 

 mens. Cones globular or broadly ovoid, ^ inch in diameter, com- 

 posed of 8 to 10 woody scales in decussate pairs, thickened at the 

 apex. Seeds winged, 3 to 5 on each scale. 



Thujopsis dolabrata was discovered by Kaempfer in Japan, where 

 it occurs in a wild state north of about latitude 35. In the southern 

 part of this area it is a mountain tree only, ascending to an alti- 

 tude of 6,000 feet. 



A plant was introduced into England by T. Lobb in 1853 

 but this specimen died. In 1861 supplies of seed were sent from 

 Japan by J. G. Veitch and Fortune, from which plants were raised 

 and generally distributed. 



The specimen figured was obtained from Ullapool, Scotland.
