NOTES
Synonymie : It is a highly polymorphic species, which is generally divided into different subspecies [i.e. Th. pulegioides subsp. chamaedrys (Fr.) Guşul., subsp. effusus (Host) Ronniger, subsp. montanus (Benth.) Ronniger and subsp. pannonicus (All.) Kerguelen] on the basis of calyx length, leaf length and width, inflorescence length and leaf hairiness. Considering the morphological variability observed in the putative diagnostic characters, the constant presence of intermediate forms, the absence of any ecological or geographical discontinuity, it is impossible to justify any subdivision of Th. pulegioides in subspecies. Waiting for further studies, we can recognize just two varieties: the glabrous plants pertain to var. pulegioides (Th. glaber Mill., Th. ovatus Mill., Th. chamaedrys Fr., Th. pulegioides subsp. montanus (Benth.) Ronniger, incl. Th. istriacus Heinr. Braun, Th. alpestris auct. Fl. Ital.) and hairy plants pertain to var. vestitus (Lange) Jalas (Th. lanuginosus Mill., Th. pannonicus All., Th. froelichianus Opiz, Th. carniolicus Borbas ex Desegl., Th. valderius Ronniger) (Bartolucci et al. 2013).
