Abstract: | ABSTRACT Eight endangered species of the Veneto region were examined from the karyological and micromorphological points of view. Their geographical distribution, the exsiccata of Herbarium Venetum (HV-PAD) and conservation problems were also considered. These species are: Cortusa matthioli L., a taxon sporadically distributed in Veneto with 2n=24 chromosomes; Calianthemum kernerianum Freyn ex Kerner, only known on Mt. Baldo (Verona) and with 2n=4x=32; Scrophularia vernalis L. with 2n=28; Kosteletzkya pentacarpos (L.) Ledeb., an entity with no regional conservation regulations and with 2n=34; Athamanta vestina A.Kerner, endemic to Italy and with 2n=22; Hottonia palustris L. with 2n=20 and in danger because of the destruction of its habitat; Sagittaria sagttifolia L. with 2n=22; Trapa natans L., a protected species in Veneto with 2n=36 and 2n=48. |
