Adiantum sericeum

A maidenhair endemic to Cuba, described by D.C. Eaton in 1869 and known from about 15 wild records spread from Pinar del Río to the east. Its ecology is poorly documented; the measured climate shows a warm island with a marked winter dry season, and many Cuban maidenhairs grow on shaded limestone, so a well-drained, lime-tolerant setup is suggested.

Where it grows wild

Probably terrestrial or on rocky, shaded ground in forest, possibly on limestone as are many Cuban Adiantum; this is inferred, not recorded.

Recorded sites range from near sea level to about 470 m; few records carry an elevation.
