Description

I currently have only this description for var. gracilis: Tree to 15 m tall with a dense pyramidal crown. Leaves dark-green, to 3 cm long and 2 mm wide. Cones cylindrical, to 5 cm long. Seeds with one wing (Harkevich and Kachura 1981).

Distribution and Ecology

Russia (Sakhalin, S. Kuril Isls, one small stand on Kamchatka), Japan (Vladimir Dinets e-mail, 2-Jan-1998). Var. gracilis is only known from one small grove (0.2 sq.km) in Semyachik valley, Eastern Kamchatka (within Kronotsky Zapovednik). Probably introduced by native people few hundred years ago (Harkevich and Kachura 1981). Hardy to Zone 5 (cold hardiness limit between -28.8°C and -23.3°C) (Bannister and Neuner 2001).

Wilson (1916) says it is abundant in Hokkaido, occasionally in pure stands but usually with Picea jezoensis and deciduous hardwoods, or, in the northern part of the island, with Picea glehnii. In Sakhalin (which at the time was Japanese, south of 50°N), he found that it "covers enormous areas" with Picea jezoensis and Larix gmelinii var. japonica, chiefly on low mountain slopes.

Big tree

Wilson (1916) says the largest trees he found were "on the slopes of Shiribeshi-san near the town of Kutchan up to 1000 m. altitude" and were up to 250 cm girth (about 80 cm dbh) and 30 m tall.
