T.  aStudies of the floral biology of neotropical Nymphaeaceae.  c1976  aA field study of the floral biology of two species of Nymmphaea (Nymphaeaceae) was made. N. rudgeana G.F.W. Meyer, a night flowering species, was studied around Manaus and Belem. It is visited by the scarab beetle Cyclocephala castanea Oliv. in the Manaus vicinity and by C. verticalis Burm. in the Belem vicinity. N. rudgeana is protogynous and cross-pollination is quite frequent. N. ampla (Salisb.) DC., a day flowering  species, was studied near Salvador, Bahia. This species is visited by the bee species Trigona spinipes. N. ampla is not protogynous and is largely self-fertilized, although a small amount of cross-fertilization may occur through the activity of the Trigona bees.  aNymphaeaceae  ataxonomy  aPlanta  aTaxonomia  aBiologia floral  aFloral biology  aPlant1 aANDERSON, A.
