Trithuria sect. Hamannia is a section within the genus Trithuria[2] native to Australia and India.[3]
Description
The dehiscent,[2][3] elliptical,[3] apocarpous, monomerous follicle fruit[4] has three longitudinal pericarp ribs.[2] The fruit does not have papillae, doesn't have distinct epicuticular wax deposits, and the apex does not have thickened endocarp cells.[2] The fruit apex also does not have a distinct beak.[3] The fruit splits into three parts along the longitudinal ribs.[4] The smooth seed has a thick cuticle. The sheathless cotyledon is strongly reduced.[2]
Taxonomy
It was described by Dmitry Dmitrievich Sokoloff, William J. D. Iles, Paula J. Rudall, and Sean W. Graham in 2012 with Trithuria lanterna D.A. Cooke as the type species.[2]
Species
- Trithuria polybracteata D.A.Cooke ex D.D.Sokoloff, Remizowa, T.D.Macfarl. & Rudall
- Trithuria konkanensis S.R.Yadav & Janarth.
- Trithuria lanterna D.A.Cooke
Etymology
The section name Hamannia honours Ulrich Hamann who worked on[2] and described the family Hydatellaceae.[6]
Distribution
Its species occur in India (Western Ghats) and Australia (tropical Western Australia, tropical northern Australia).[3]
Phylogeny
Trithuria sect. Hamannia split from Trithuria sect. Altofinia about 6 million years ago in the Upper Miocene.[1][7]
