Arrojadoa dinae subsp. dinae
Arrojadoa dinae subsp. eriocaulis

Arrojadoa dinae subspec. nana at the type site in Minas Gerais

Furthermore, a dwarf subspecies Arrojadoa dinae subsp. nana (PJBraun & Esteves) PJBraun & Esteves.

Meanwhile, the temporarily under Dinae Arrojadoa out Arrojadoa eriocaulis Buining & Brederoo (1973), Arrojadoa beateae including PJBraun & Esteves (1989). Arrojadoa heimenii , Arrojadoa hofackeriana (PJBraun & Esteves) PJBraun & Esteves (2002) and Arrojadoa multiflora F.Ritter ( 1979) again recognized as a separate species and thus also included in the IUCN Red List.
