Fig. 23. Ecology Occurs as terrestrial in lowland rain forest. Taxon discussion This species is easily recognizable by the 2 - 5 pairs of pinnae, cuneate at base, and tubular yellow to orange glands on the receptacle ( Smith 1983 ). The presence of these glands is shared with T. (Meniscium) andreana (Sodiro) C.V.Morton, the closest species to T. (Meniscium) arcana ( Smith 1983 ).
