Ecological Park of Gunma in Par¨¢ State. It reports the main diagnostic characters
and provides new systematic data for the group. In addition, it locates the
production and accumulation sites of bioactive compounds to determine possible
adaptive strategies of these species in the Amazon rainforest environment.
Diagnostic structural features include stoma typology, central veins and margin
forms, type of mesophyll, and the presence of schlerenchymatous sheaths in the
cortex, among others. Among the bioactive compounds related to defense
adaptation are phenolic compounds, which occur in all three species, and
alkaloids and mucilage, which are exclusive to</span><i><span style=\"font-family:Verdana;\"> E. laminarioides</span></i><span style=\"font-family:Verdana;\">. Of the
three species studied, </span><i><span style=\"font-family:Verdana;\">E. lami</span></i></span><i><span lang=\"EN-US\" style=\"font-family:Verdana;\">narioides</span></i><span lang=\"EN-US\" style=\"font-family:Verdana;\"> has features that make it the best
suited to the rainforest environment.</span><span lang=\"EN-US\"><o:p></o:p></span>
