Alopecurus glaucus Less. | |
Publ. & Syn. | Alopecurus roshevitzianus Ovcz., Fl. URSS 2: 154, 745 (1934). Type: Siberia: the Kolyma area, "inter Pochorskoje et Panteleevskoje, in declivibus fl. Kolyma", 28. July 1905, leg. I. Schulga 1396. |
Notes | Elven and Murray: Tzvelev (PAF proposal and comment) recognized the northern Alopecurus roshevitzianus apart from the more southern A. glaucus s. str. Pending further investigations, we enter the more widely circumscribed species. Alopecurus glaucus (including A. roshevitzianus) differs in several characters from A. borealis and is without transitions towards it in the material we have inspected (northwestern North America, ALA). We accept it as species. On the American side, this species is mainly interior and alpine, and only one arctic occurrence is yet documented at Cape Prince of Wales (COLO, CAN-472963) on the Seward Peninsula, western Alaska. |
Chromosomes | (1) 70 (10x). - Avdulov (1931, for A. alpinus var. elatus). (2) ca. 100-ca. 120 (ca. 14-ca. 17x). - Siberia (S), Far East (N), Canada/U.S.A. - At least five reports. |
