34 Nr. 2. C. H. OSTENFELD and C. SYRACH LARSEN: 
upon the basis of his own observations (Wırson: 1916, 
pp. 30—31), and he states that is has a tendency to form 
pure growths of considerable extent, otherwise occurring 
only in company with other conifers such as Pinus densi- 
flora, Abies homolepis, A. Veitchti, Picea jezoensis, Tsuga 
diversifolia, and deciduous foliage trees, such as oak, birch, 
hornbeam and beech. SırasawA, however, states that it 
most frequently occurs in mixed forests (SırasawA: 1910, 
p. 307). As a rule, it attains a height of 25—26 m. with a 
girth of 2—3 m.; but it can, under exceptional circums- 
tances, reach 33 m. with a girth of 4 m. In speaking of 
its occurrence upon Fuji-Yama, Wırson remarks, that 
Pinus pumila as a rule is not found here, and consequently 
the light-loving L. Kaempferi is allowed to dominate in these 
greater altitudes, where otherwise Pinus pumila is the only 
ruling tree or shrub. 
The recurved cone-scales, which are generally very 
distinctive, make L. Kaempferi an easily recognisable larch. 
It varies in size, and large cones are common in cultivated 
specimens. Mayr, who may be supposed to have been 
intimately acquainted with the species in its native country, 
states that the cones only attain a length of 1,5—3 cms. 
in their natural habitat, becoming as long as 3,5 cms. 
under cultivation (Mayr: 1890, p. 65). He mentions the 
illustrations in SIEBOLD & ZUCCHARINI: Fl. Jap. II, 1842 
(Plate 105), which reproduce two cones 3,5 cms. in length, 
as an example of a cultivated specimen with large cones. 
Under culture in Denmark, this tree has produced cones 
as long as 4 cms. (Strodam near Hillergd, and Tinning 
Forest near Friijsenborg). 
The female cone in the flowering stage is violet; the 
bracts have a green mid-rib; the species seems to vary
