Abstract
Caryological data on «Arisarum proboscideum» (L.) Savi. II. – In specimens of «Arisarum proboscideum» (L.) Savi collected near Acerno (Salerno) two different chromosome numbers – 2n = 28 and 2n = 42 – have been found. In two localities of Tuscany (Consuma, in the upper Valdarno, and San-sepolcro, near Arezzo) only the number 2n = 28 has been found, as it was already reported for Reggello (FABBRI 1966a). Moreover, in regard to the number of female flowers present in each spadix, a greater variability has been observed in the Acerno and Avellino populations (1 – 6 fem. flowers; see FABBRI 1966b) than in the Tuscan ones (1 – 3 fem. flowers); this difference in variability could be possibly connected with the different caryological situation.Keywords
