The present species is unique in the genus because it lacks petals. Moreover, it differs from T. acutangula, the species it resembles most, in the sepals being as densely hairy inside as outside. The apetalous flowers with a broad and flat disc are also found in other genera like Glenniea Hook. f. and Mischocarpus Blume.
