Abstract
In this contribution, new chromosome data regarding two taxonomically critical genera of the Italian flora, namely Plantago and Sesleria, are presented. All the specimens analysed in this paper were collected in the Italian territory and include three chromosome counts for Plantago (P. albicans, P. crassifolia, and P. subulata) and two counts for Sesleria (S. caerulea and S. nitida).
Highlights
A few examples of polyploidy have been reported so far (Gremaud 1979). It is the first chromosome count for this species in Italy (Bedini et al 2010 onwards), and it represents a new cytotype for the C. personata, for which the following chromosome numbers were reported for other countries so far: 2n = 16, 18, 22 (Rice et al 2014)
The chromosome number found in plants from Alpe della Luna is the same as that found in plants from other Italian localities (Favarger 1973, Brullo et al 1978, Bellomaria and Hruska 1983) and from populations of Eastern Europe (Rice et al 2014)
The chromosome number found is typical for this subspecies, and was reported for other localities from central Italy (Bartolucci and Peruzzi 2014)
Summary
It is the first chromosome count for this species in Italy (Bedini et al 2010 onwards), and it represents a new cytotype for the C. personata, for which the following chromosome numbers were reported for other countries so far: 2n = 16, 18, 22 (Rice et al 2014). It is the first chromosome count for this species in Italy (Bedini et al 2010 onwards).
