137 The Trees of Great Britain and Ireland 



P. Glehnii attains its maximum development in Yezo, where, according to 

 Mayr, it is much commoner in the west of the island than in the east. In western 

 Yezo it forms mixed forests in company with P. ajanensis, chiefly on the cooler 

 parts of the mountains, the trees reaching on an average nearly 1 20 feet in height. 

 Mayr mentions a peculiar forest of this species, which occurs on the volcanic Iwo- 

 san (1500 feet elevation) east of Lake Kucharro. In the eastern part of the island, 

 it forms pure forests in the river valleys in swampy situations, which are often 

 several hundreds of acres in extent ; but the trees are of no great size, averaging 

 only 80 ft. in height. This species is known to the Japanese as Shinko matsu or 

 Aka-eso. 



According to Miyabe, it is rare near Sapporo and only found at high elevations 

 mixed with P. ajanensis. Near Lake Shikotsu at 1500 feet elevation, I found it 

 much less abundant than P. ajanensis, and could not procure any fruiting specimens. 

 A self-sown seedling which I brought from here is growing very slowly at Coles- 

 borne and is now only 1 foot high. 



I could not learn whether the wood of the tree is distinguished from that of the 

 common Yezo spruce. Some very broad clean pieces which I saw in the saw-mill 

 at Sunagawa had a close grain and a shiny satiny surface when planed, making it 

 suitable for interior work where strength is not required. 



Cultivation 



According to Beissner ' seeds of this species arrived in Germany before 1891, 

 from which young plants were raised. It is scarcely known in cultivation in England. 

 There are young plants at Kew, about 2 ft. high, which are thriving ; and small 

 specimens at Bayfordbury and Brickendon Grange, Herts, and in the Cambridge 

 Botanic Garden. It is too soon as yet to form any opinion as to the suitability of 

 this species to our climate ; but I do not expect that it will attain any size.
