Batianoff’s Paspalum Grass (Paspalum batianoffii)
Batianoff’s Paspalum Grass was described in 1992, it was collected in the Statue Bay, about 6,5 km southeast of the town of Yeppon in the Gladstone District (formerly Port Curtis District) in Queensland, Australia.
The species had 20 to 40 cm long, creeping stems.
Batianoff’s Paspalum Grass inhabited a very narrow foredune with open wood land consisting of some common, widely distributed plant species, it was found growing directly above the flood mark, acting as a sand stabilizer.
***
The species is apparently extinct today, however, the reasons for this appear to be unknown.

Amphicarpic Paspalum Grass (Paspalum amphicarpum)
The Amphicarpic Paspalum Grass was described in 1942, it appears to be endemic to the western regions of Cuba: the type was collected in 1923 at the edge of a pool near Laguna de Piedras in the Province of Pinar del Río [it might actually also occur in South America, I wasn’t able to find out yet].
This is a glabrous, widely creeping aquatic or subaquatic perennial with ascending branches, it is furthermore known to produce subterranean spikes with cleistogame (self-pollinating) flowers as well as normal aerial inflorescences. [1][2]
***
The species’ name appears in lists of extinct species, so is extinct at least on the island of Cuba to which it might have been endemic.
