chromosomes. A further karyotype analysis was performed by Benedf i Gonzalez (1987)<br />
who indicates the chromosome formula 12m + 2M + 2st-sat + 2t-sat for plants from near<br />
Barcelona. Karyotype analyses performed for the present study yielded a chromosome<br />
formula <strong>of</strong> 10m + 4sm + 4st-sat for two Moroccan populations and a more symrnetric<br />
karyotype with 14m + 4st-sat for a S Spanish population (Table 3).<br />

This interesting biennial to perennial subspecies <strong>of</strong> <strong>Anthemis</strong> arvensis endemie to the<br />
mountains <strong>of</strong> Sicily and S Italy, had been studied cytologically only once, by Brullo & al.<br />
(1978a) who found a diploid chromosome set <strong>of</strong> 2n = 18 chromosomes (12m + 4sm + 2tsat)<br />
in a Sicilian population. <strong>The</strong> present count from the Calabrian mountains corroborates<br />
this data.<br />

<strong>The</strong> haploid and diploid chromosome numbers mentioned above were already reported<br />
earlier (<strong>Oberprieler</strong> 1994). <strong>The</strong> karyotype was found to be very symrnetrical, consisting <strong>of</strong><br />
5 pairs <strong>of</strong> metacentic, 2 pairs <strong>of</strong> submetacentric, and 2 pairs <strong>of</strong> satel\ited subtelocentric<br />
chromosomes (10m + 4sm + 4st-sat, Table 4).<br />
