Notes:
Meteorium is stated to contain some 30 species with a pantropical distribution; probably 3-5 species in the Neotropics. The genus is characterized by the often plicate, concave, auriculate, broadly ovate to ovate-lanceolate leaves, single costa, mostly uni- pluripapillose laminal cells, and little differentiated alar cells. Asexual reproduction is probably common via deciduous attenuate or flagellate branches. The generic concept follows that of Bruce Allen for Central America.
 
Meteorium contiene unas 30 especies con una distribución pantropical, ca. 3-5 especies en el Neotrópico. El género se caracteriza por presentar hojas a menudo plegadas, auriculadas, anchamente ovadas hasta ovado-lanceoladas, costa simple, células de la lámina generalmente pluripapilosas, rara vez unipapilosas y células alares poco diferenciadas. La reproducción asexual es probablemete común, via ramas deciduas atenuadas o flageladas.
