study of the material identified as Ouratea gillyana reveals the presence of two taxa: (1) typical O. gillyana with slender pedicels 1 m m or less in thickness, flower buds nanowly ovoid, 2.5-3.5 m m wide, relatively shorter inflorescences (3.5-7.5 c m long), more crowded and more numerous flowers with a tendency to occur in fascicles of 2-3 on some part of the rachis, and nanower leaves 1-4 c m wide, and (2) O. gillyana subsp. pachypoda with stout thickened pedicels 1.5-2 m m in thickness, flower buds broadly ovoid to suborbicular-ovoid, 4-5 m m wide, relatively longer inflorescences 6-13 c m long, flowers solitary and less crowded, and leaves averaging wider, (2.5-)4-7 c m wide. Ouratea gillyana is similar to O. steyermarkii Sastre, but diflfers in the chiefly racemiform inflorescence with the flowers b o m e above the middle portion of the rachis, and usually two sepals
