Peperomia leptostachya

Peperomia leptostachya, commonly known as slender peperomia or hairy peperomia, is a small succulent herb in the pepper family Piperaceae found in most parts of the Paleotropic floristic kingdom, from Africa through Asia to Australia and the western Pacific.

Taxonomy
The hairy peperomia was first described by the British botanists William Jackson Hooker and George Arnott Walker Arnott in 1832, based on material collected in Hawaii. In 1973 the German botanist Ruprecht Düll reduced this to varietal status, giving it the name Peperomia blanda var. leptostachya which became the accepted name for approximately 40 years. More recently, in 2020, the Belgian botanist and Peperomia authority Guido Mathieu published a paper reverting the plant back to its original name.
