291 



leaves obtuse: cones oblong, 3-4 inches long; scales truncate or slightly 

 emarginate at apex; bracts lanceolate, reflexed. Southwestern China and 

 Himalaya. — Introduced first in 1848 and later repeatedly, but it never 

 succeeded in cultivation. 



3. L. Kaempferi, Sarg., not Carr. (Z. leptolepis, Murr. L. japonica, Carr.). 

 Japanese L. Tree to 90 feet tall, with short horizontal branches; bark gray 

 peeling off in narrow strips leaving red scars; brand Jets yellowish- or reddish- 

 brown, glabrous, usually bloomy the first year; spurs sliort and globular: 

 leaves rather broad, obtuse, soft, K-lH inches long, light or bluish-green: 

 cones ovoid-oblong, K-lK inches long, w^ith emarginate roundish ovate 

 scales. Japan. — Introduced in 1861 by J. G. Veitch to Great Britain. Hardy 

 as far north as Massachusetts and one of the handsomest and most rapidly 

 growing larches. The dwarf form of the high mountains of Japan, var. minor, 

 Sarg. (L. leptolepis var. viinor, Murr.), reverts under cultivation to the 

 normal form. 



A hybrid of this species and L. decidua is L. eiirolepis, 

 Henry {L. Henryana, Rehd. L. hyhrida, Farquhar, not 

 Schroed.). Dunkeld L. Tree of vigorous growth, in- 

 termediate between the parents. From L. Kaempferi 



differs chiefly in the less bloomy young branchlets, yellow 



or grayish-yellow the second year, in the 



shorter and narrower leaves with fewer rows 



of stomata; from L. decidua in the slightly 



bloomy branchlets and in the larger leaves, 



those of the shoots with the stomatic bands 



above composed of 2-4 and the bands beneath 



composed of 5-7 rows o/ stomata, those of the 



spurs with 1 or 2 rows on each side above and 



with 3-5 rows on each side beneath. It origi- 

 nated about 1900 at Dunkeld, Scotland, and 



was introduced to the Arnold Arboretum 



in 1910. 



4. L. decidua, Mill. (Z. europoea, DC. L. 



Larix, Karst.). European L. Fig. 78. Tree 



to 100 feet tall, with pyramidal, later often 



irregular, head; bark dark grayish-brown; /\ ^ 



branchlets slender, glabrous, yellowish: leaves ''//J. .,,
