    Uma estrutura peculiar em gotículas de lipídeos, nas células foliares de coffea
    (Instituto Agronômico (IAC), 1968-11) Kitajima, E. W.; Landin, C. C.
    Droplets of lipid nature , 1-10 μ in diameter, are cytoplasm of leaf cells of many Rubiaceae plants. presentIn ultra-thin sections, examined by meanes of the electron micros­ cope, they appear structureless, with a relatively electron transparent content in most of the studied genera (Cinchona, Coffea, Ixora, Garde­ nia, Genipa and Psychotria). Usually these droplets are surrounded by a dense line, the nature of which is not clear as yet. In some species of Coffea (C. arabica, C. eugenioides, C. dewevrei and C. racemosa), however, lipid droplets contained bundles of sinuous tubular elements, about 40 mμ, in diameter and undetermined length.
