| Bupleurum triradiatum Adams ex Hoffm. | |
| Publ. & Syn. | Hoffm., Gen. Pl. Umbell.: 115 (1814). Described from the Lake Baikal area (Siberia). |
| Notes | Murray and Elven: We identify some plants from the Arctic in South Chukotka with Bupleurum triradiatum (specimens seen from Mount Dionysia 20 km south-southeast of Anadyr town). These plants differ from the southern Siberian ones only in being smaller and conform to B. triradiatum in Krasnoborov's key and diagnostic characters. Compared with the two other species below, B. triradiatum is characterized by few rays in the main umbel (very rarely as many as five), broadly clasping upper leaves and main bracts, and broadly ovate to obovate, rhombic bractlets. It differs distinctly from the other northern plants. |
| Chromosomes | 16 (2x, x = 8). - Far East. - Arano and Saito (1977); Krogulevich and Rostovtseva (1984). Several of the other numbers and reports included for the aggregate above probably belong to this species. |
