Thymbra capitata (L.) Cav.
Thymus carstiensis (Velen.) Ronniger – Note: This species was considered as a hybrid between Th. longicaulis C.Presl and Th. pulegioides L., but it has been
recently revaluated as an independent species (Bartolucci et al. 2017c).
Thymus herba-barona Loisel. – Note: For the taxonomy of this species, see Molins et al. (2011).
Thymus illyricus Ronniger
Thymus longicaulis C.Presl subsp. longicaulis – Note: All the Alpine records of this species have to be referred to other taxa (Bartolucci and Domina 2014).
Thymus moesiacus Velen. – Note: Several records of Th. oenipontanus Heinr.Braun ex Borbás from central and southern Italy should be referred to this species.
Thymus moesiacus [= Th. chaubardii (Boiss. & Heldr. ex Rchb.f.) Čelak. var. subisophyllus Borbás ≡ Th. longicaulis C.Presl var. subisophyllus (Borbás) Jalas] is
closely related to Th. glabrescens Willd. subsp. urumovii (Velen.) Jalas. [= Th. callieri Borbás ex Velen. var. microcalyx Degen & Urum.], and further studies are
needed to establish the systematic relationships among these taxa.
Thymus oenipontanus Heinr.Braun ex Borbás – Note: The distribution of this species needs further investigations. For its nomenclature, see Bartolucci and
Scharfetter (2015).
E Thymus paronychioides Čelak. – Note: For the nomenclature, taxonomy and distribution of this species, belonging to Th. sect. Hyphodromi (A. Kern.) Halácsy,
see Bartolucci and Peruzzi (2014) and Bartolucci and Domina (2015).
E Thymus picentinus (Lacaita) Bartolucci – Note: The records of Th. thracicus Velen. from southern Italy have to be referred to this species (Bartolucci et al. 2013;
Bartolucci and Mráz 2016).
E Thymus praecox Opiz subsp. parvulus (Lojac.) Bartolucci, Peruzzi & N.G.Passal.
Thymus praecox Opiz subsp. polytrichus (A.Kern ex Borbás) Jalas
Thymus praecox Opiz subsp. praecox
T Thymus pseudochamaedrys (Heinr.Braun) Ronniger – Note: The taxonomic identity of this species, closely related to Th. oenipontanus Heinr.Braun ex Borbás,
is still unclear. In addition, both these names are yet to be typified.
Thymus pulegioides L. – Note: 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.) Kerguélen] 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 Borbás ex Déségl., Th. valderius Ronniger) (Bartolucci et al.
2013).
