Taxon discussion

In his revision of Neotropical Cyclodium , Smith (1986) cited that this species and Cyclodium seemannii (Hook.) A.R.Sm. can be distinguished from all other species of the genus by the round-reniform indusia. Cyclodium trianae can be readily separated from C. seemannii by the lack of sessile and globose glands in the lamina abaxially ( Smith 1986).
