Adiantum alomae

A Cuban maidenhair fern described by Caluff in 2009, known from limestone around Santiago de Cuba in the east of the island. Specimens come from dry sea cliffs below the Morro Castle, rocky creek walls at Aguadores, and limestone slopes of Monte Picote. It suits a warm, bright, well-drained rock-crevice setup with a dry winter.
