incurved at the shortly pointed apex, keeled above and below, 

 overlapping, pressed to the branchlets for about half their length ; 

 bands of stomata on all four surfaces ; leaves of young trees 

 narrowly linear, sickle-shaped, compressed, keeled above and 

 below. CoJies shortly cylindi"ic, \ in. long, with numerous, over- 

 lapping, rounded, mucronate scales, each with a minute bract 

 at the base. Seeds two on each scale, oblong, broadly winged. 



Discovered on the western slope of Mount Morrison, Formosa, 

 at 6,000-8,000 ft. elevation, by Konishi in 1904, and introduced 

 to Kew in 1920, where there are small plants in the Temperate 

 House.

A deciduous or, in one variety, a semi-evergreen tree 100-150 

 ft. high, and 4-6 ft. in trunk diameter, of pyramidal habit when 

 young, but developing a wide and often flattened crown when 

 old. When growing on well-drained land the trunk usually 

 tapers from base to summit, but when in marshy ground or 

 surrounded by water the base becomes conspicuously buttressed 

 or enlarged, and is usually hollow internally. In wet and swampy 

 places, woody, cylindrical, or oval protuberances, known as 

 " cypress knees," often arise from the roots ; these projections 

 are sometimes several feet high, more than a foot in diameter, 

 and hollow. Bark of old trees reddish-brown, fibrous, ridged, 

 peeling off in long strips. On the young wood the bark is 

 at first green or glaucous green, afterwards bright brown and 

 roughened by circular scars left by the fall of deciduous branchlets. 

 Branchlets at the points of shoots persistent, lateral branchlets 

 falling with the leaves in autumn. Buds near the tip of the shoot 

 rounded, with overlapping, sharp-pointed scales. Smaller lateral 

 buds are also present, and from them leafy, budless branches arise 

 which fall in autumn. Leaves spirally arranged on the branchlets, 

 but on the deciduous shoots appearing in two ranks owing to a 

 twist near the base, narrow, short pointed, ^| in. long where 

 they appear in two ranks, shorter and scale-like on the persistent 

 branches, delicate green in spring, yellowish green in summer, 

 rich brown in autumn, with greyish stomata on the under-surface. 

 31 ale and female flowers appearing on the same tree in spring, 

 the former in slender, purplish, tassel-like clusters, 3-6 in. (rarely
