Notes | Aiken: Aiken et al. (1994) investigated the possibility of recognizing taxa within what they regarded as Arctagrostis latifolia subsp. arundinacea and found no reason for accepting any of the approximately eight taxa that have been named, mainly by Nash. There are very good reasons for reducing all the Nash taxa to synonymy (Aiken and Lefkovitch 1990; Aiken et al. 1994; Aiken 1999). As to A. angustifolia, this is one of three species besides [A. macrophylla and A. "pooides"] described in the genus by Nash. Aiken et al. (1994) considered this to be merely part of the phenotypic plasticity that can be expressed in A. latifolia subsp. arundinacea, and they found no reason to recognize the taxon at any rank. Elven: We assume that also the numerous species described from Asia belongs within A. arundinacea: A. anadyrensis V.N. Vassil., A. aristulata Petrov, A. caespitans V.N. Vassil., A. calamagrostidiformis V.N. Vassil., A. festucacea Petrov, A. glauca Petrov, A. parviflora Petrov, A. stricta Petrov, A. tenuis V.N. Vassil., A. tilesii Petrov, and A. viridula Petrov. |
Chromosomes | (1) 28 29 30 (4x). - Far East (N), North America. - Several reports. The Alaskan reports of Bowden (1960a), Mitchell and McKendrick (1975), and Mitchell (1992) almost certainly belong to this taxon. (2) 42 (6x). - Far East (N). - Two reports. (3) 56 (8x). - North America. - Bowden (1960a, omitted by Löve and Löve 1975a). Arctagrostis arundinacea is predominantly but not exclusively tetraploid. |
