Trithuria sect. Altofinia is a section within the genus Trithuria native to Australia. [2]

Contents

Description

The indehiscent, [2] [3] slightly beaked, [3] apocarpous berry fruit [4] with papillae does not have longitudinal ribs or distinct epicuticular wax deposits on the surface. [2] The fruit stalk bears a distal constriction, serving as an abscission zone. [3] The smooth seeds have a thick cuticle. [2]

Taxonomy

It was described by Dmitry Dmitrievich Sokoloff, William J. D. Iles, Paula J. Rudall, and Sean W. Graham with Trithuria cowieanaD.D. Sokoloff, Remizowa, T.D. Macfarl. & Rudall. as the type species. [2]

Species

It has two species: [2]

Etymology

The section name Altofinia is derived from altus meaning elevated or high, and finis meaning limit or boundary. It refers to the geographic distribution of its species, which occur on the upper end of the Northern Territory, Australia. [2]

Distribution

Its species occur in Australia (Northern Territory). [2] [3]

Phylogeny

Trithuria sect. Altofinia split from Trithuria sect. Hamannia about 6 million years ago in the Upper Miocene. [1] [5]
