Sesleria apennina Ujhelyi
Sesleria argentea (Savi) Savi
Sesleria autumnalis (Scop.) F.W.Schultz

Sesleria caerulea (L.) Ard. subsp. caerulea
Sesleria calabrica (Deyl) Di Pietro
Sesleria insularis Sommier subsp. barbaricina Arrigoni
Sesleria insularis Sommier subsp. insularis
Sesleria insularis Sommier subsp. morisiana Arrigoni
Sesleria italica (Pamp.) Ujhelyi – Note: According to Ubaldi (2016), S. italica subsp. mariculensis Ubaldi would differ from the typical Sesleria italica for a number
of quantitative character states, mainly concerning panicle length and leaf width. Considering the high morphological variability in the whole genus Sesleria,
the continuous variation and the absence of any ecological or geographical discontinuity between the two putative subspecies, it is very difficult to justify
their recognition. The study of the type specimens designated by Ujhelyi (1959), kept in BP and FI, and of living and dried specimens collected in Galeata
(locus classicus of S. italica) confirmed that the features putatively diagnostic of S. italica subsp. mariculensis are also shown by S. italica s.str.
Sesleria juncifolia Wulfen ex Suffren subsp. juncifolia
Sesleria kalnikensis Jáv.
Sesleria nitida Ten. subsp. nitida
Sesleria nitida Ten. subsp. sicula Brullo & Giusso
Sesleria pichiana Foggi, Gr.Rossi & Pignotti
Sesleria pulchella (Chiosi) Ubaldi – Note: The taxonomic value of this taxon is doubtful. Apparently, S. pulchella is mainly related to S. italica (Pamp.) Ujhelyi,
and, at a first glance, it seems simply marked by extremely reduced dimensions. Waiting for further karyological, molecular and biometric studies, we provisionally
accept S. pulchella as a good species.
