238 THE CULTIVATED EVERGREENS 



long: cone about ^ inch long with about 15 leathery scales; seeds 

 oblong, with the wing about ^ inch long. High mountains of Formosa 

 and southwestern China. — Introduced to the Arnold Arboretmn in 1918 

 by E. H. Wilson; young plants are growing in California and Florida. 

 When young it is a very handsome tree of broad- 

 pyramidal outline with ascending branches and long 

 pendidous branchlets; the foliage is very similar to that 

 of Cryptomeria. 



15. ATHROTAXIS, D. Don. 



Evergreen densely branched trees; bark peeling o£F in 

 longitudinal shreds : leaves homomorphic, small, alternate 

 or indistinctly decussate, either short, blunt, scale-like 

 and appressed, or lanceolate and somewhat loosely 

 disposed: flowers monoecious; staminate flowers in imbri- 

 cated spiral aments, the anthers 2-celled; fertile flowers in 

 spirally imbricated aments, 3-6 ovules under each scale, 

 these aments becoming small globular cones with woody 

 scales which are contracted at base and at apex peltately 

 dilated or pointed; seeds 3-6, winged; cotyledons 2. 

 (Name derived from Greek athroos, crowded, and taxis, 

 arrangement; alluding to the crowded cone-scales and 

 leaves.) — Three species in Tasmania. One or the other of 

 these species which were introduced to Great Britain in 

 1857 by Wm. Archer may be in cultivation in this country 

 either in the open in the Southern States or in California 

 or as a greenhouse plant in the North. (^H^
