1838 The Trees of Great Britain and Ireland 



It seems likely to succeed as well and to grow larger in this climate than the 

 common balsam poplar. Those which I have planted in a cold heavy soil and a 

 situation where severe spring and autumn frosts occur regularly, grow very fast and 

 are perfectly healthy. I received them from Messrs. Meehan of Philadelphia in 

 1903, and one of those measured in 191 1 no less than 32 ft. high by 1 ft. 5 in. in 

 girth, though its branches have been cut several times to propagate. On account 

 of its large handsome leaves, which in hot weather diffuse a most fragrant smell for 

 some distance, this is one of the best of all poplars for ornamental planting. 



The largest tree on the continent, appears to be one in the Dresden Botanic 

 Garden, which Mr. Bean 1 in 1908 estimated to be 70 to 80 ft.. high, with a trunk 

 5 ft. 10 in. in girth. In the Copenhagen Botanic Garden it is 30 ft. high, and very 

 thriving. A small tree in the Christiania Botanic Garden was also doing well in 

 1908. (H. J. E.) 



POPULUS MAXIMOWICZII 



Populus Maxim owiczii, A. Henry, in Gard. Chron. liii. 198, fig. 89 (1913). 



Populus suaveolens, Regel, Tent. Fl. Ussur. 132 (1861); Maximowicz, in Bull. Soc. Nat. Mosc. liv. 



51 (1879) ; Komarov, Fl. Manshurice, ii. pt. i. 17 (1903) (not Fischer). 

 Populus balsamifera, Linnaeus, var. suaveolens, Burkill, in Journ. Linn. Soc. (Pot.) xxvi. 535 (1899) 



(not Loudon); Shirasawa, Icon. Ess. Forest. Japon, i. text 37, t. 18, figs. 11-24 (1900). 



A tree, attaining 100 ft. in height and 10 ft. in girth. Branchlets densely 

 pubescent. Leaves (Plate 410, Fig. 24), about 4 in. long, and 3 to 3^ in. broad, 

 nearly orbicular, oval, or broadly elliptic ; subcordate at the rounded base ; cuspidate 

 at the apex ; pubescent on the midrib, nerves, and veinlets of both surfaces, whitish 

 or tinged with rusty red beneath ; densely ciliate and sharply serrate in margin ; 

 petiole densely pubescent. Fruiting catkins 7 to 10 in. long ; capsules glabrous, 

 sub-sessile, 3- to 4-valved. 



This species, owing to the peculiar shape and pubescence of the leaf, is remarkably 

 distinct from P. suaveolens, with which it has been confounded, and is most closely 

 allied to the Himalayan P. ciliata. It is the common balsam poplar in eastern Asia, 

 extending from Kamtschatka southwards through Saghalien to Japan, Amurland, 2 

 Manchuria, and Korea. (A. H.) 



This is the only poplar which attains a large size in Japan, where it is 

 common in Hokkaido and in the north-eastern district of Honshu, and is called 

 doro-noki. I saw it in the central parts of Hokkaido, the largest near Lake 

 Shikotsu being about 100 ft. by 12 ft., growing on river banks and also mixed 

 with other trees in deciduous forests ; 8 but in some parts of the country there

8 Elwes found what he believes to be this tree planted at the railway stations on the Siberian Railway near Harbin in 

 May 1912, and brought home cuttings which have rooted at Colesborne. It is recorded for Saghalien by Koidzumi in Journ. 

 Coll. Sci. Tokyo, xxvii., art. 13, p. 44 (1910). 



3 Such a forest is figured in Forestry 0/ Japan, 96, issued in 1910 by the Bureau of Forestry, Department of 

 Agriculture and Commerce, Tokyo. Jack, in Milt. Dtut. Dtnd. Ges. 1909, p. 282, fig. 285, gives an illustration of an old 

 tree in Hokkaido with deeply furrowed bark.
