Description

The dehiscent fruit is a apocarpous monomerous follicle, which splits into three parts.Romanov, M. S., Bobrov, A. V. C., Iovlev, P. S., Roslov, M. S., Zdravchev, N. S., Sorokin, A.

=Etymology=
The section name Trithuria is derived from the Greek words τρεις treis meaning "three", and θυρις thyris meaning "window". It references the dehiscence of the fruit.Hooker, Joseph Dalton, Fitch, W. H., & Reeve Brothers. (1844). The botany of the Antarctic voyage of H.M. discovery ships Erebus and Terror in the Years 1839-1843 :under the command of Captain Sir James Clark Ross (Vol. 3, Issue 2, pp. 78-79).

Distribution
Phylogeny
Trithuria sect. Trithuria split from Trithuria sect. Hydatella about 16 million years ago in the Early Miocene.Lin, Q. (2014).
