Ecology: Amazon and Pantanal; on soil and burnt tree trunk. Elevation: 170-180 m. Distribution: Southwest Amazon basin (including Bolivia), Southeast Asia and Pacific.
Brachymenium coarctatum is the only member of the genus found in humid and semi-humid Amazon and Pantanal lowlands. Unlikely to be confused with any other bryaceous species in the lowlands; features of this species include the lanceolate leaves with a long acuminate apex and relatively long excurrent costa. Specimens examined are usually in poor condition, rather contorted and brittle, due to the dry period in which the material was collected.
