| Draba subcapitata Simmons | |
| Publ. & Syn. | Simmons, Vasc. Pl. Ellesmereland: 87 (1906). Lectotype (O!): Canada: Nunavut, Ellesmere Island, "ad litus orientale sinus Goose Fjord Ellesmerelandiae meridionalis, Yellow Hill", 23. Aug. 1901, leg. H.G. Simmons 3591. See notes. |
| Notes | Grundt and Elven: In northwestern Europe, Draba subcapitata is common in Svalbard. It is present also in high mountains in northern Scandinavia (Sweden and Norway) but does not reach the Arctic. Mulligan has annotated the specimen above as lectotype of the name D. subcapitata. We have not found any relevant publication. It does not matter much, as the meaning of this Simmons name is unambiguous. The affinity of D. subcapitata has been disputed. Tolmachev assigned it to series Pilosae, whereas he assigned D. fladnizensis to series Lacteae. Petrovsky commented that D. subcapitata should be assigned to series Oblongatae ("Micropetalae"). However, recent investigations of morphology, isoenzymes, and RAPDs (Scheen et al. 1999, 2002) and sequencing of several genes (Grundt et al. 2004) prove a close relationship with D. fladnizensis and also with the central Asian D. altaica Bunge (this name was applied to the arctic plants before Simmons' publication of D. subcapitata). If we apply series, these three species should be included in the same one. |
