(PANCIC)PURK. in the Drin River valley of the Balkan Peninsula, where it grows at altitudes between 600-1400 m (JOSIFOVIC1970, DÉBAZAC 1977).

Picea obovata has the widest distribution in Asia, extending throughout Siberia (SOKOLOV et al. 1977). This species occurs at latitudes up to 68-70°N with a northernmost limit in the Khatanga River valley at 72°15'N. It occurs in several taiga forest types together with species of pine, larch, and fir. It co-occurs with P. jezoensis (SIEB et ZUCC.) CARRIÈRE in northeastern Asia. Several other species of spruce form forests in the far northeastern regions of Asia, including P. glehnii (Fr. Schmidt) Masters, P. polita (Sieb et Zucc.) Carrière, P. alcoquiana (VEITCH ex LINDL.) CARRIÈRE (=P bicolor), and P. koraiensis NAKAI (WANG 1961; KURATA 1964; KURATA and HAMAYA 1971; 1974; OHWI1965; HORIKAWA1976). The southernmost occurrence of the genus is in Taiwan, where the endemic P. morrisonicola HAYATA grows at about 23°N (LI 1975).

More than 30 species of spruce have been reported from eastern and southeastern China and central Asia (REHDER and WILSON 1916; Lee 1935; BOBROV 1970; CHENG et al. 1975; LIU 1982; FARJON 1990, 2001). The taxo-nomic position of a number these species is not clear. Only a dozen or so of the
