it reaches a height of 25—30 m., according to REHDER & 
Witson, but A. E. PRATT observed specimens west of Ta- 
tsien-lu as high as 40 m. (Engl. Bot. Jahrb. XLVIII, 1913, 
p. 746). The crown is more slender in shape than that of 
L. Griffithiana, the branches of the first order being des- 
cribed as rather short. Branches of the second order are, 
on the contrary, pendulous in both species. 
Single individuals of the species attain their best growth 
in the fertile, lower-lying, forest districts, but it only occurs 
scattered among other conifers and deciduous-leaved trees, 
and is more specially found along the sides of water- 
courses. It becomes more and more common as the ground 
rises, and in the highest-lying districts whole forests are 
composed of it. 
It was introduced into Germany in 1899 under the 
name of L. chinensis. Seeds of it were sent to BEISSNER, and 
plants were successfully raised (BEISSNER: Nadelholzk. 1909, 
p. 305; vide ELwes & HENRY: Trees Gr. Brit. and Irel. II, 
1907, pp. 346—347). It was subsequently introduced into 
England, when Witson in 1904 sent seeds from Szechuan 
to Veitch’s Nursery Gardens. It is not found under cultiva- 
tion in Denmark.
