Distribution and habitat:— Meniscium maxonianum is distributed in Venezuela, Colombia, Peru to Bolivia and Brazil. It grows in forest formations of Amazonian forest, Atlantic rain forest, and Cerrado domains, where it can grow in shaded and sunny areas at 1– 720 m.
Notes:— The most notable character of M. maxonianum is the dense cover of sessile to stalked glands on the abaxial surface of the laminae, and having the sporangial stalks glabrous or with inconspicuous filamentous, septate structures. In these characters it differs from the similar M. longifolium, which shares the same shape of lamina and pinnae, but is characterized by having glands and trichomes (sometimes only trichomes) on the abaxial surface of the lamina and sporangial stalks with long, acicular trichomes. Another species that also has glandular trichomes on the abaxial surface of the lamina is M. falcatum Liebmann (1849: 183). However, it differs from M. maxonianum by having longer pinna stalks and acicular and erect trichomes on the costae.
