Tribe Loteae has major diversity centres in the Mediterranean region and in California. However, four monospecific genera are restricted to other parts of Africa and Asia. This paper is focused on the monospecific Asian genus Podolotus, which is crucial for understanding evolution of Loteae. Evidence from four DNA markers (nrITS, psbA-trnH, petB-pe...

Bunium is unusual in Apiaceae in having a variable cotyledon number and broad infrageneric dysploidy. To test the monophyly of the genus, phylogenetic relationships among 39 Bunium species were investigated with DNA sequence data from nuclear (nrITS) and plastid (psbA-trnH intergenic spacer) regions. Several other taxa with a similar ecology and ge...

Lotus creticus is a potentially important perennial legume for soil management in the Mediterranean climate. This plant is in focus of experimental research in different countries. The so-called Lotus creticus group is taxonomically problematic. Although some authors consider all members of the group as a single variable species, others segregate s...

Some new nrITS sequences of Lotus are produced and added to the data set analysed in DEGTJAREVA et al. (2006). Lotus burttii and L. filicaulis are revealed as members of the /Lotus corniculatus clade. Lotus conimbricensis is found to be sister to the entire /Lotus corniculatus clade; the /Lotus pedunculatus clade is more distantly related. The New...

Molecular phylogeny shows that the temperate legume tribe Loteae is close to the mostly tropical Robinieae and monogeneric Sesbanieae, but comparative morphological studies of these groups are limited. Unusual patterns of inflorescence symmetry and calyx development have been described in some Loteae, but taxon sampling was low. We studied these fe...

The genus Pinguicula (Lentibulariaceae) is unusual within the dicot order Lamiales because of the occurrence of both embryos with two cotyledons and those with just one cotyledon. In order to elucidate the infrageneric relationships and the evolutionary history of the embryo, we analysed (1) the internal transcribed spacers ITS1 and ITS2 of the nuc...

Nuclear ribosomal ITS sequence data as well as morphological data show that Dorycnopsis gerardii (L.) Boiss. can not be placed in the genus Anthyllis L. The genus Dorycnopsis Boiss. includes two species, D. gerardii and D. abyssinica (A. Rich.) V.N. Tikhom. et D.D. Sokoloff (=Vermifrux abyssinica (A. Rich.) J.B. Gillett). Morphological similarity b...
