46 Oberprieler: Anthemis in N Africa
The finding of n = 9 and 2n = 18 chromosomes for this variety of Anthemis secundiramea
agrees with a report by Brullo & al. (1977, sub A. secundiramea subsp. intermedia)
. Brullo (in Bartolo & al. 1979) later found two pairs of satellited chromosomes in
plants from Lampedusa which he considered to represent a separate subspecies,
A. secundiramea subsp. lopadusana, on account of its karyogram (12m + 2sm + 4st-sat),
as he had found that A. secundiramea subsp. secundiramea lacked satellites. The Tunisian
plant material studied here shows two pairs of satellited subtelocentric chromosomes
(Table 8), exaetly as the morphologieally similar plants from Lampedusa. This supports
the inc1usion of A. secundiramea subsp. lopadusana in A. secundiramea varo cossyrensis
deseribed from Pantellaria.

-Me, Paradise Bay, 27 Feb 1994, Mevert & Seifert s.n. (Herb. Oberprieler).
This taxon, endemie to Malta, had been studied eytologically by Brullo & al. (1997).
The ehromosome number reported here is in agreement with their findings.
