A tree attaining in Japan 120 feet in height and 12 feet in girth. 

 Bark reddish - brown, scaling off in longitudinal flakes. Ultimate 

 branchlets flattened. Leaves appressed with spreading mucronate 

 tips ; lateral pair conduplicate, acute ; facial pair flattened, ovate- 

 acuminate, obscurely glandular. Foliage shining green above, 

 marked below with conspicuous white patches. Leaves on the 

 main axes equal, in four ranks, | to ! inch long, with spreading 

 acuminate points. 



Cones on short scaly branchlets, globose, \ inch in diameter, 

 dark brown when mature ; scales usually ten, depressed in the 

 centre with a minute point. Seeds one or two on each scale, 

 brown, ovate, with prominent resin-vesicles and broad lateral wings. 



Cupressus pisifera, which is indigenous in the central and 

 southern parts of the main island of Japan at an elevation of 

 2,000 to 5,000 feet, was introduced into England in 1861 by J. 

 Gould Veitch. It is now common in cultivation. 



The following well marked varieties occur : 



Var. squarrosa (Masters). Retinispora squarrosa (Siebold and 

 Zuccarini). Usually a shrub with glaucous, silvery foliage ; leaves 

 soft in texture, in opposite decussate pairs or in fours, decurrent 

 on the branchlet, sessile, linear, acicular, flattened, {- inch long. 

 This is a variety in which the juvenile foliage is retained in- 

 definitely. It is cultivated in Japan, where it is said to occur also 

 as a wild tree ; and was introduced into Europe in 1843. 



Var. plumosa (Masters). Retinispora plumosa (Veitch). A 

 dense shrub or small tree, usually of conical habit. Branchlet 

 systems crowded, more or less overlapping, bi-pinnate, with the 

 pinnae in one plane. Leaves crowded in decussate pairs, I inch 

 long, subulate, ending in a sharp cartilaginous point, concave from 

 side to side, and whitened on the inner surface. This was intro- 

 duced from Japan by J. Gould Veitch in 1861. 



Var. filifera (Masters). Retinispora filifera (Standish). A shrub 

 or small tree with spreading branches and long pendulous branch- 

 lets, undivided for the greater part of their length and terminating 

 towards the end in bi-pinnate divisions. Leaves in decussate pairs, 

 subulate, sharp-pointed, about \ inch long, decurrent, white on their 

 inner surface.
