Green manure is considered a viable and sustainable alternative to agricultural land. The positive highlight this practice results from the proof of the harmful effects of joint-soluble fertilizers with high oil costs and industrial fertilizers. Thus Leguminosae family has been the most used as green manure, as it brings many both the soil and to the plants. In this family there is the Mucuna p ruardievanns ta(Lg.e) sD fCor. (Leguminosae, Faboideae) species as one of the most used for this practice. However knowledge about their biology and especially in relation to aspects of floral biology and their pollinators about various species used as green manure are scarce. rTehpisro sdtuucdtyio ani mofe gdr etoe nv emraifyn uarsep Mecutcsu onfa fplorruarli ebniosl.o Fgoyr athnids , pwoell ininavteionnto trhieadt itnhfelu wenecaelt ht hoef fploorllainl avtiosrit obrse haanvdi opro lalinnadt/oorrs ; flvoerarilf ievdi saitso rm; oarnpdh olaongayl yaznedd flothrael bMio.l opgryu rinieflnuse nfceer titlhitey components through its fruiting rates and seed formation. To study the floral biology flowers were observed as to their flowering time and duration of anthesis. Visa also is change of color in the floral parts and stigmatic receptivity at all stages of flower development. Morphometry of flowers by the material preserved in FAA and in natura was verified. For the morphological and anatomical study of the keel light microscopy and scanning electron microscopy was used. The floral visitors were observed during their foraging activities and made autogamy test for the presence of spontaneous self. For fertility components was observed a difference in fruit development positions isne ethdes bina sthael, fmruiditsd lep oasnitdio nasp.i cTahl ein Mflo.r epsrucreiennces falonwd etrh ea ndthiffeesriesn hcaev ien stheeve fno rdmaaytsio. nA roef heteroclamídeas with purplish corolla dialipétala and zigomorfa.
