| Veratrum viride Aiton | |
| Publ. & Syn. | Aiton, Hort. Kew. 3: 422 (1789). Described from eastern North America. |
| Notes | Veratrum viride s. lat. is a tetraploid North American species or species group with two well separated (widely allopatric) taxa: subsp. viride in the east but south of the Arctic, and subsp. eschscholtzii (V. eschscholtzii) in the west and bordering on the Arctic. McNeal Jr. and Shaw (2006) argue for treatment as two races rather than species. |
| Chromosomes | (1) 64 (8x). - Far East (Koryak). - Sokolovskaya (1968). (2) 70-72 (ca. 9x). - Sokolovskaya and Strelkova (1960). (3) 80 (10x). - Far East (N). - Several reports, numerous counts. (4) 96 (12x). - Far East (West Chukotka). - Zhukova and Petrovsky (1976). Not included: A report of 2n = 32 (4x) from Putorana in northern Siberia (Krogulevich 1976a). This count was made on plants from within the range of the tetraploid V. album rather than V. oxysepalum and may be based on a misidentification. There are two other excluded reports of tetraploids, both published in papers dealing with technical cytological questions wherein the identification of the plants is uncertain. |
