Peperomia beckeri E. F. Guim. & R. J. V. Alves

Becker’s Peperomia (Peperomia beckeri)

Becker’s Peperomia was described in 1998 “from an old but well preserved herbarium specimen” that had been collected in 1965; it was endemic to the Ilha da Trindade some 1500 km offshore the eastern coast of Brazil, an island that suffered extremely from the introduction of feral mammals, especially goats that had been introduced already in 1700. These goats ate away nearly the whole vegetation of the island, leading to the complete loss of the former forest.:

Before 1821, however, something or some event had killed them – killed them all – leaving a weird landscape of standing corpses. It was, in the words of one who saw it, “a forest of desolation, as if nature had at some particular moment ceased to vegetate.”” [1]

When the goats were finally removed from the island in 2005, the flora recovered very quickly, especially the fern species, which apparently survived in the form of spores in the ground. Becker’s Peperomia, however, was never found again, despite field searches. [3]

The species was believed to have been rediscovered in 2009, however, these plants later turned out to have been another, misidentified species. [2][3]

Peperomia leucorrhachis Sodiro ex C. DC.

White-shafted Peperomia (Peperomia leucorrhachis)

The White-shafted Peperomia, described in 1920, is known only from the type collection that was made in the 19th century in the forests of the western Andean slopes in the Pichincha Province of Ecuador.

The species was never recorded since and is possibly extinct.

Peperomia pichinchae C. DC.

Pichincha Peperomia (Peperomia pichinchae)

The Pichincha Peperomia was found growing along the streams on the slopes of the Pichincha Volcano in the Pichincha Province, Ecuador.

The species was apparently not found in recent decades and is considered possibly extinct, yet it could also exist in nearby areas, however, I unfortunately could not find out anything about it so far.

Peperomia subpetiolata Yunck.

Waikamoi Peperomia (Peperomia subpetiolata)

The Waikamoi Peperomia, named ‘ala ‘ala wai nui in the Hawaiian language, is known from a single population near the Kula Pipeline between the Puohokamoa- and the Waikamoi Streams in eastern Maui, Hawaiian Islands.

The species itself is apparently extinct, however, there apparently still exists a hybrid of this species and the Forest Peperomia (Peperomia hirtipetiola C. DC.) that is kept in cultivation.

Peperomia glandulosa C. DC.

Glandulose Peperomia (Peperomia glandulosa)

The Glandulose Peperomia was described in 1890, it was originally only known from the type material that was collected in the late 19th century somewhere in the surroundings of the city of Loja in the Loja Province, Ecuador.

The species was collected again in the 1960s but apparently not again, it might already be extinct.

Peperomia degeneri Yunck.

Degener’s Peperomia (Peperomia degeneri)  

Degener’s Peperomia is known exclusively by the type collection that was made in 1928 in eastern Moloka’i, Hawaiian Islands.

The forests of Moloka’i are overrun by introduced invasive plant species and by plant-eating ungulates, the species was never recorded since the type collection and is very likely extinct.

Peperomia petraea C. DC.

Rock-dwelling Peperomia (Peperomia petraea)

The Rock-dwelling Peperomia is known only by the type material that was collected in the 19th century along the Río Huambi near the town of Puembo, a rural parish in the Metropolitan District of Quito, the capital city of Ecuador.

The area has lost almost all of its native vegetation and this species very likely is extinct.

Peperomia pululaguana C. DC.

Pululahua Peperomia (Peperomia pululaguana)

The Pululahua Peperomia is known from only two populations, which both were last recorded more then 100 years ago, one on the slopes of the Pichincha Volcano and the other one on the slopes of the Pululahua Volcano both in the Pichincha Province, Ecuador.

The species apparently was not found in recent decades and might be extinct.
