Beitr. 29/1 247-297 31.7.1997 On the distribution of Lathyrus L. species (Fabaceae) in Lazio (Central Italy) R. MORTELLARO & M. COLASANTE Abstract: Information about the distribution of species helps us to settle the se- paration of infrageneric taxa and are also useful to interpret the evolution of the ob- served genus. Here we refer to the distribution of Lathyrus species in Lazio (Central Italy) with information obtained from herbaria, field and Bibliographic data. In our investigation we found that some taxa need a complete systematic revision to solve their taxonomic problems concerning mainly a lot of intermediate forms which pro- bably are natural hybrids between some closely related taxa. It is obvious that the corresponding distribution feels the effect of this. In our opinion, according to recent investigations, we consider the following nineteen species to be spread in Lazio: L. amphicarpos L., L. annuus L., L. aphaca L., L. cicera L., L. clymenum L., L. hirsutus L., L. latifolius L., L. linifolius (REICHARD) BÄSSLER, L. niger (L.)
