| Alnus incana (L.) Moench | |
| Publ. & Syn. | Moench, Methodus: 424 (1794). - Betula alnus var. incana L., Sp. Pl.: 983 (1753). Lectotype (UPS): Europe. Herb. Burser XXIII:9 (Jonsell and Jarvis 1994: 153). |
| Notes | The situation in Alnus incana resembles that found in A. viridis with several overlapping and intergrading taxa probably best treated as subspecies. |
| Chromosomes | 28 (2x). - Canada (British Columbia). - Taylor and Mulligan (1968). Not included: A report of 2n = 28 from "North America" (Löve 1954b for A. crispa var. sinuata in an untrustworthy paper). For some reason, Löve assumed A. crispa s. str. to be European despite it being described from Canada. |
