New plant species discovered hidden among rocks in a Colombian river

A new plant species, identified as 'Peperomia daironii,' has been discovered by researchers from the Botanical Garden of Bogotá. This small plant grows discreetly among rocks in a forested area near Caño Cristales, a renowned natural attraction in Colombia's Meta department.

This discovery marks the first formal registration of a species from the subgenus Tildenia in Colombia. While related specimens have been found in botanical collections, no species from this group had been officially described in the country until now. The finding occurred in an ecosystem known for Caño Cristales, often called the "river of five colors" due to its vibrant aquatic plant life.

'Peperomia daironii' had remained hidden from scientific observation due to its diminutive size and unique life cycle. It is classified as a geophytic and rupicolous herb, meaning it possesses an underground tuber that allows it to survive unfavorable periods. The plant is adapted to grow on rocks, where it develops its entire structure.

During dry seasons, the plant's leaves wither and vanish, leaving only the dormant tuber concealed. With the return of the rains, the species regenerates, producing new leaves and reappearing on its rocky habitat. The new species is named in honor of the late Colombian botanist Dairon Cárdenas, recognized for his significant contributions to understanding the flora of the Amazon and Orinoquía regions.
