Chromosome numbers in the tribes Anthemideae and Inuleae (Asteraceae)
No full text9 p.Twenty-two chromosome counts of 19 taxa (21 populations) in the tribe Anthemideae and one member (one population)
of the tribe Inuleae of the family Asteraceae are reported. The Anthemideae studied belong to the subtribes
Artemisiinae (14
Artemisia
taxa, and one species each of the genera
Dendranthema
,
Filifolium
and
Neopallasia
) and
Tanacetinae (one species each of the genera
Lepidolopha
and
Tanacetopsis
). From the Inuleae, we studied one
Inula
species. Five counts are new reports (including two at generic level), six are not consistent with previous counts
and the remainder are confirmations of very limited (one to four records) previous data. Most of populations of
Anthemideae studied have the basic chromosome number
x
=
9, with ploidy levels ranging from 2
x
to 10
x
. Dysploidy
is also present, with two
x
=
8 diploid taxa. The species of Inuleae studied is a diploid with
x
=
10, also indicating dysploidy,
other members of the same genus
Inula
having basic numbers of
