Dwarf Pipewort (Eriocaulon minutissimum)
The Dwarf Pipewort, a very dwarf species, that reaches a height of not even one centimeter, was scientifically described in the year 1925.
This species is known only from the type material, which was collected near the city of Pinar del Río in the same-named Cuban province.
The type locality seems not to exist any longer, and the Dwarf Pipewort is considered most likely extinct.

Paspalum amphicarpum Ekman
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.
