Our analysis further revealed that the traditionally used characters (glabrous vs. hairy adaxial surface and presence vs. absence of a scarious margin to the tip of the lowermost bracts) are not taxonomically informative. The characters best differentiating the species include indument on the lowermost vernal internodium, length of mature stylodia, length of glandular hairs on sepals and maximum diameter of mature seed. A key for identification of both species is also provided. A revision of almost 1600 specimens deposited in 16 Central European herbaria revealed that the species show different distribution patterns in Central Europe and partial habitat segregation. Specimens from the Czech Republic previously assigned to C. litigiosum were identified as C. pumilum; consequently, C. litigiosum must be removed from the Czech flora.
