The species M. excelsa is one of the few rainforest trees to grow in pure stands.Ivan T.

Uses

The beans of Mora spp. are edible if boiled, and are also the source of a red dyestuff.O.N. Allen and Ethel K. Allen, "The Leguminosae" (Madison: Univ. Wisconsin Press) pp. 445-446

Some of the species are important for timber production. Mora excelsa and Mora gonggrijpii are also known as nato, and are commonly used in guitar body and neck construction.
