Asplenium congestum

A little-known spleenwort described by Carl Christensen and endemic to Ecuador, where the IUCN lists it as Data Deficient. The only specimen with good locality data comes from tropical rain forest at 300 m on the upper Río Tiputini in Amazonian Ecuador. Grow it as a warm, humid, shaded forest fern, and treat all details as provisional.

Where it grows wild

The IUCN classes its habitat as moist lowland and montane tropical forest. The one well-documented collection is from tropical rain forest at 300 m in the Amazonian lowlands. Whether it grows on the ground, on rocks or on trunks is not recorded in the sources consulted. Terrestrial is assumed here, but many Asplenium in these forests are low epiphytes.

The reliable record is at 300 m. An old 1911 specimen is given as 2,350 m plus or minus 650 m, and its GBIF coordinate falls on Quito at about 2,860 m, which is probably a generic locality rather than the true site.
