(b) Subsp. curvisepala (Lindman) Franco View in CoL , Feddes Repert. 79: 39 (1968)
(C. curvisepala Lindman): Fruit ellipsoid to subglobose, dark red, crowned by deflexed sepals. Woods. E. C. Europe, extending to S. Russia and W. Bulgaria; S. Sweden and S. Finland.
C. x kyrtostyla Fingerli. , Linnaea 4: 372 (1829) ( C. calycina x monogyna , C. heterodonta Pojark. ), found in the lowlands of N.W. Europe, is like 9 (a) but differs mainly in the cuneate leaves with oblong, acute lobes with only a few teeth at the apex, main veins curving downwards and fruits crowned by deflexed sepals.
C. plagiosepala Pojark. , Nov. Syst. Pl. Vase. (Leningrad) 1965: 135 (1965), from S.E. Poland, is very like 9 (b) but has longcuneate, usually 3-lobed leaves and patent or erecto-patent sepals 4-5-5-5 mm; its status is uncertain.
