The distribution of this species was limited to the coastal cliffs of the island of Alejandro Selkirk, then still called Más Afuera, in the Juan Fernández archipelago of Chile.
It was a kind of miniature version of a tree rarely more than 50 cm high, with a 10 to 20 cm high, about 1 cm thick trunk that was more or less covered by dead leaves. The leaves themselves were very narrow, almost ribbon-like, and were described as strongly succulent.
The photo below is from 1920 and shows a plant that was sown in 1919 and bloomed just a year later.
Unfortunately, the specimen pictured died without producing any fertile seeds, otherwise the species might still exist today, even if only in cultivation.
The last representatives of this species were found in 1991, two already badly battered specimens were all that was left over from the insatiable hunger of the introduced goats that were found all over the island. All later search expeditions were completely unsuccessful – the species is now extinct.
… macabre but true:
These goats, for their part, are widely regarded as a special breed (Juan Fernández goats) and are kept in zoos that specialize in keeping rare or even endangered breeds of domestic animals.

The Pulney Pimpernel, described in 1919, was restricted to the Western Ghats in Tamil Nadu, India, the plant was formerly used by several of the native tribes as a medical plant to treat hemorrhoids (?).
The species was last recorded in 1891 and is now considered most likely extinct.
