Sobre a ocorrência dos estômatos "Graminóides" em espécies do gênero Virola e em outras Dicotiledôneas.

"Graminaceous" stomata were observed in Virola (Myristicaceae). Comments are made on the widespread occurrence of this type of stomata as well as the need for additional structural information which can show a variation gradient between the characteristic stomata type of the Graminae and Cyperaceae and the "graminaceous" stomata of dicotyledons.
