Abstract: Mapania belongs to Mapanioideae, a quite controversial subfamily in Cyperaceae due to the existence of unusual characters in both reproductive and vegetative organs. The genus is represented by seven species in Northern Brazil but taxonomic valuable information related to the leaf organs is still unknown. The present study aimed the anatomical description of the leaf organs (either basal leaves or cataphylls and involucral bracts) of three representative Brazilian species of Mapania. Samples of cataphylls, bas… Show more

“…Leaf samples were progressively dehydrated in an ethanol series (50%, 70%, 85%, 95%, and 100%) and infiltrated with warm paraffin; leaf transverse sections (8–12 μm) thickness were then cut using a rotary microtome (Leica RM2255, Germany). Lignified tissues were red‐stained using Safranin and non‐lignified cell walls were blue‐stained with Fast Green to Blue stain, leaf sections were then mounted in slides and sealed with neutral glue (Garcia, Potiguara, Kikuchi, Demarco, & Aguiar‐Dias, ; Ocheltree, Nippert, & Prasad, ; Silva, Alves, & Coan, ; Sobrado, ). The slides were observed and photographed under a light microscope (Leica DM2500, Germany).…”
