Summary A karyological analysis on Italian populations of 3 species, belonging to the genera Cephalanthera and Listera (Orchidaceae: Neottieae tribe) and characterized by asymmetrical karyotypes, was undertaken. Karyomorphological and C-banding data strongly suggest that in 2 species, namely C. damasonium and L. cordata, chromosomal rearrangements involving the large and medium-large chromosomes constituted the principal mechanism of chromosome evolution. This process is particularly evident in L. cordata, where karyotype evolution occurred by means of centric fission along with an increase in chromosome number and in the overall chromosomal heterochromatin content. Altogether the present observation on Italian specimens of the Neottieae corroborate previous proposals of a central role of Robertsonian rearrangements and quantitative heterochromatin variation in karyotype reorganization.

“…ex Aiton fil. The observed chromosome number of 2n=34 in all individuals from different localities, coincides with previously reported data (Kliphuis 1963, Meili-Frei 1966, Scrugli 1980, moreover examination of metaphase I in embryo sac mother cells revealed 17 bivalents. Some authors reported different chromosome numbers, i.e.…”

Résumé.· Treize taxons de la famille des Orchidées (tribu des Neottiae Lindl.) ont été étudiés d'un point de vue caryologique. Les nombres chromosomiques précédemment cités chez huit d'entre eux, de même que l'aneuploïdie signalée chez Epipactis atrorubens, E. helleborine, Goodyera repens et Listera cordata ont été retrouvés dans les populations du sud de la France. A l'exception de Goodyera repens et Spiranthes spiralis diploïdes et caractérisés par un caryogramme symétrique, toutes les autres espèces sont remarquables par leur état tétraploïde et des caryogrammes fortement dissymétri· ques.Summary.· Thirteen taxons from the Orchids family ( tribe of Neottiae Lindl.) were studied for their caryology. Chromosome numbers were confirmed for eight of them and also the aneuploidy previously mentioned for Epipactis atrorubens, E. hel/eborine, Goodyera repens and Listera cordata in populations from the south of France. Except for Goodyera repens and Spiranthes spiralis which are diploids and characterized by a symetrical karyogram, ali the species are characterized by their tetraploidy and highly non symetrical karyogram.
