Abstract
In the present study morphological, anatomical, polynological and molecular biology features of the genus Utricularia L. belonging to Lentibulariceae family of Lamiales were studied. This genus contains two species, namely: U. minor L. and U. australis R. Br. The morphological characters of the two species such as the stolone length, presence or absence of rhizoids and bags shape (bladder) of the trapper are different. In anatomical studies, the epidermal stem cell shape, thickness and shape of aeranchymous cells and cortex are useful for separation of these two species from each other. In palynological studies, it was revealed that pollen of studied taxa are multi-aperature and without pore and ornamentation of exine surfce is also grooved. Results from chloroplasty analysis of trnL-F sequences indicate that U. australis and U. minor are related with U. macrorhiza and U. intermedia. respectively.
