2n=
(1) 16 17 (2x, x = 8). - Far East (N), Alaska, Canada. - Numerous reports.
(2) 32 (4x, x = 8). - Far East (East Chukotka). - Yurtsev et al. (1975); Zhukova (1983). These two reports are probably based on the same count.
Not included: Gillett et al. (2007) reported the following chromosome numbers for this taxon: 2n = 14 and 28. The primary sources have 2n = 16 and 32 and Yurtsev commented that x = 7 is characteristic of sect. Gamotion (with H. alpinum and H. americanum) rather than of sect. Multicaulia (with the H. boreale group). Yurtsev assumed that the counts of 2n = 14 and 28 probably reflect a period when the name H. boreale s. lat. was connected to H. hedysaroides. These secondary reports are therefore omitted.
Geography: Amphi-Beringian (E) - North American: RFE ALA CAN.
