Abstract

The morphological and anatomical characters of the spermoderm of 49 native and foreign taxa in Wettstein’s
tribe Solaneae were investigated for their delimitation as well as for a speculation of their phylogenetic status.
The observations culminated into the suggestion of an identificatory key. Taxonomic changes including
transference (re-allocation) and addition were done for some taxa. Nomenclatural amendments for some other
taxa were suggested and a new species, Atropa lutea, has been reached at. The phylogenetic status of the studied
taxa was speculated relying on the number of the spermoderm layers. Multi-layered spermoderm was considered
less advanced than the few-layered one.
