1528 Galium spurium L.

This species occurs in most of Eurasia and in parts of N. America. The map includes G. vaillantii DC. (syn.: G. spurium var. vaillantii [DC.] Gren. & Godr.). These taxa are sometimes referred to G. aparine (no. 1514). G. spurium s. lat. belongs to the circumpolar plants (Hultén, Circumpol. II, p. 280 and map 271). In the Mediterranean region var. tenerum (Gaud.) Gren. & Godr. also occurs. It has spread for instance to C. Africa and New Zealand. In N. America probably both native and introduced taxa occur.
