A.  aIdentification and distribution of C3 and C4 grasses in open and shaded habitats in Sao Paulo State, Brazil.  c1989  aThe photosynthetic pathway of grasses collected in several vegetation formations in Sao Paulo State, Brazil, was identified by leaf anatomy. Of the 78 species collected, 48 sun species and seven shade species possessed the C4 pathway. Twenty-three species possessed the C3 pathway, of which three were sun species and 20 were shade species. The result indicates that the C4 species and more abundant in open habitats and C3 species in shaded habitats. The data also show the taxonomy distribution of the photosynthetic pathways. All genera of the collected species are exclusively C3 or C4, except Panicum which has both C3 and C4 species.  alight  ashade  aCerrado  aFotossíntese  aIndigenous organisms  aLuz  aPhotossynthesis  aPlanta nativa  aSombra1 aJOLY, C.
