| Gentianopsis barbata (Froel.) Ma | |
| Publ. & Syn. | Ma, Acta Phytotax. Sin. 1: 8 (1951). - Gentiana barbata Froel., Gentiana: 114 (1796). Described from the Tom River (Siberia). - Gentianella barbata (Froel.) Bercht. & J. Presl, Prir. Rostlin. 1: 22 (1823). |
| Notes | We accept two races of Gentianopsis barbata for the Arctic, one Asian and amphi-Beringian and one geographically much more restricted northwestern North American. |
| Chromosomes | (1) 44 (4x, x = 11). - Europe (Iceland). - D. Löve (1953); Löve and Löve (1956b). (2) 78 (6x, x = 13). - Europe (Iceland). - Löve (1983b); Löve and Löve (1986a). The chromosomal information is ambiguous. Löve and Löve (1975a) stated the base number in Gentianopsis to be x = 11 and the number in this species to be 2n = 44 and tetraploid, based on two counts from Iceland. Subsequent works, also by the Löves, have rather indicated x = 13, and for northern material the hexaploid number of 2n = 78, in both G. detonsa and G. barbata (see below). The difference is rather large. None of the two reported numbers have been confirmed by any independent source we are aware of. We are tempted to reject the earlier reports of 2n = 44. Not included: A report of 2n = 26 for a plant named in the publication (Vasudevan 1975) as G. detonsa from the western Himalayas. Gentianopsis detonsa should not occur in the Himalayas, whereas many other species of the genus do. The report, however, gives support to x = 13 as the base number of this genus. |
