Morphological, Anatomical and Reproductive Differences between Riccia cavernosa Hoffm. and Riccia crystallina L. in the Liverwort Flora of Turkey

Riccia is the largest genus among Turkish Liverwort Flora with 26 taxa (24 species and 2 varieties). Identification of Riccia species are quite difficult because of too similar morphology of the especially closely related taxa. R. cavernosa and R. crystallina are morphological similar taxa and generally confused together in field trips. In this study, morphological, anatomical, reproductive, ecological and distributional information's with detailed photos and drawings of these species have been given.
