About

Ramonda heldreichii is a species of flowering plant in the family Gesneriaceae. It was formerly treated as Jankaea heldreichii, the only member of the monotypic genus Jankaea. It is endemic to Mount Olympus in Greece where it is a relict species from the Tertiary period.

Where it grows

Ramonda heldreichii is endemic to the northern and eastern slopes of Mount Olympus in Greece. It typically grows in damp cracks and crevices on limestone rocks on the northern and eastern sides of the mountain, especially near streams. Its altitudinal range is between 400 and 2,400 m (1,300 and 7,900 ft) but it is most common between 700 and 1,400 m (2,300 and 4,600 ft). It is a relict species from the tertiary period; it once had a more widespread distribution but as the climate changed, suitable habitat for the plant dwindled, and it became confined to its present range.
