According the most recent data, the key for
1 | Flowers globular, closed due to overlapping sepal edges; petals, stamens and pistils not visible during flowering |
|
– | Flowers bowl-shaped, saucer-shaped or, if globular, always open: sepal edges do not overlap; petals, stamens and pistils visible during flowering |
|
2 | Petals longer than sepals and protrude from the flower |
|
– | Petals equal to sepals or shorter |
|
3 | Sepals 5–7. Petals 30–40 mm long, 1.5–2 times longer than sepals. Persistent styles 3.5–5 mm long |
|
– | Sepals 8–14. Petals 20–28 mm long, 1.2–1.5 times longer than sepals. Persistent styles 1.5–3 mm long |
|
4 | Petals 1.5–2 times longer than stamens |
|
– | Petals shorter |
|
5 | Persistent styles and stigmas purplish-black or often blackening. Persistent styles 2.5–3 mm long (Plants from the Altai Republic) |
|
– | Persistent styles and stigmas light green or yellow-green. Persistent styles less than 2 mm long |
|
6 | Plants 80–100 cm high. Sepals 5–9 (12) |

|
7 | Sepals reddish-orange. Persistent styles 0.5–1 mm long |

8 | Plants bloom prior to leaf expansion. Sepals white or pale cream, finely dentate along the edge, do not fall long after flowering. Leaflets up to 25 mm long. Persistent styles 8–18 mm long, equal to or longer than the ovary, thin, straight or slightly curved |
|
– | Plants bloom with leaves developed. Sepals from pale yellow to orange, typically smooth-edged, fall at the end of flowering. Leaflets up to 15 (18) mm long. Persistent styles not more than 5 mm long, several times shorter than the ovary, more or less thickened, incurved |
