PINACE^ 505 



below, marked with a broad, white patch of stomata ; surface 

 without resin glands, giving off a faint odour of turpentine when 

 bruised. Cones |-f in. long ; scales wedge-shaped, leathery 

 or woody, with a prominent, triangular, pointed and often 

 hooked boss near the apex. Seeds five at the base of each fertile 

 scale, thin, rounded, winged on each edge. 



Two well-marked forms of this conifer occur wild in Japan : — 



Var. australis, Henry. 



A tree 40-50 ft. high with a slender trunk and drooping 

 branches, or occasionally found as a shrub in the shade of other 

 trees. Branchlets flat, the lateral leaves with curved, hooded 

 points. Cones broadly ovoid, the scales thickened at the apex, 

 which ends in a blunt, triangular process. 



This is the form known in cultivation and may be regarded 

 as the type. 



Var. Hondai, Makino. 



A tree attaining 100 ft. in height with a trunk up to 10 ft. 

 or more in girth. Branchlets more closely set and overlapping 

 and leaves smaller and more crowded tho.n in the preceding, the 

 lateral leaves blunt and not curved inwards at the apex. Cones 

 globular ; scales not thickened at the apex, the boss reduced to a 

 narrow ridge or short point. Seed ivings broader than in var. 

 australis. This is the northern form of the species. 



Of the garden forms the most noteworthy are : — 

 Var. nana, Carriere. 



Var. latsevirens, Lindley. 



Dwarf and compact in habit with slender, much- divided 

 branchlets and bright green foliage. Introduced by J. G. Veitch, 

 in 1861. 



Var. variegata, Fortune. 



Leaves variegated with creamy white, the variegation often 

 occurring in patches. It is less effective than the normal forms. 

 Introduced by Fortune in 1861. 



T. dolabrata is easily distinguished from all other Thuyas 

 by its stouter branches with distinct pointed terminal buds, 

 by its larger leaves, which are conspicuously white beneath, and 

 by there usually being five seeds to each fertile scale. 



It is an important forest tree in Japan. Wilson ^ saw the 

 type growing wild near Toge Station at about 2,700 ft. altitude 

 on the borders of Uzen and Iwashiro provinces, around Yumoto 

 in the Nikko region, and in the valley of the Kiso-gawa. In the
