[EN] Chromosome counts are reported for 15 species of the family
Asteraceae from Inner Mongolia (People’s Republic of China). This study
includes representatives of the tribes Anthemideae (Artemisia, Chrysanthemum,
Filifolium, Hippolytia and Neopallasia), Astereae (Heteropappus) and Cardueae
(Echinops and Olgaea). The significance of the chromosome counts is discussed
for each species. Within the Anthemideae, chromosome counts for Hippolytia
alashanensis (2n=36) and the tetraploid level of Artemisia eriopoda (2n=36) are
reported for the first time. The chromosome number of Heteropappus altaicus
(Astereae) agrees with previous reports of one (4x) of the two ploidy levels
reported for this taxon. As a complement to the karyological data, genome size of
the Cardueae representatives was assessed using flow cytometry. Within this tribe,
Echinops gmelini (2n=26) and its sister taxon E. acantholepis (2n=14) show
strongly divergent karyological patterns of difficult interpretation, whereas the
count of E. przewalskyi (2n=32), assigned here for the first time, coincides with
those of its close relatives. In Olgaea tangutica, the chromosome count (2n=24)
and genome size (2C=3.01 pg) given here are the first reports for both the species
and the genus.
