| Pachypleurum alpinum Ledeb. | |
| Publ. & Syn. | Ligusticum mutellinoides auct., non (Crantz) Vill. (1779). |
| Notes | Elven and Murray: The relationship between Pachypleurum alpinum and the central European Ligusticum mutellinoides (transferred to Pachypleurum by Holub 1983b) remains to be clarified. Tutin (1968b) considered them one species with the comment: "The Russian populations are sometimes given specific status as L. alpinum ... Plants having the fruit characters of L. alpinum occur sporadically in the Alps; the only reliable distinguishing character of the Russian plants appears to be the somewhat less dissected leaves". We find at least the northern Siberian plants to differ from the Alpine ones. |
| Chromosomes | (1) 22 (2x). - Far East (N). - Gurzenkov and Gorovoy (1971); Zhukova and Petrovsky (1980). (2) 44 (4x). - Siberia (S). - Rostovtseva (1976). (3) 54 (ca. 5x). - Russia (N), Siberia. - At least three reports. Not included: European reports of 2n = 22 referred by Löve and Löve (1975a) under their Pachypleurum alpinum. They synonymized our species with the European Alpine Ligusticum mutellinoides. |
