摘要：
The genus Scilla has recently been split into two genera, Scilla s. str. and Ledebouria, based on morphological characters of South African species. This splitting, as well as the phylogenetic relationships between these genera and the related genera Drimia and Drimiopsis, is here discussed in the light of cladistic analyses of morphological and DNA sequence data of species from tropical Africa, the Mediterranean and India. Two chloroplast DNA regions are analysed: the intergenic spacer between the tRNA genes L(UAA) and F(GAA) and the L(UAA) intron.
