This member of the Polypodiaceae family was described by Edwin Bingham Copeland in 1931, and later by Richard Eric Holttum as Phymatodes crustacea. It is found Indonesia, Thailand and Malaysia. It grows in trees with some water and some sun. The hollow rhizomes will grow up to three centimetres in diameter, and the leaves will grow up to 35 centimetres.
The genera name after some Lecan, but I fail to figure which one, or perhaps Greek lekane; 'bowl', and Latin pteris; 'fern'. The genera name Lecanopteris was introduced by Caspar Georg Reinwardt published in Flora 8, 1825. The species name from Latin crusta, meaning 'a hard (or brittle) shell or rind'.
