Peperomia praeruptorum
A Peruvian Andean peperomia described by Trelease in 1936 from Pennell's collection near the Río Yanamayo below Pillahuata in Cusco, at about 2300 m. The name means 'of steep cliffs', and it was described as a fairly large, branching, rock-dwelling herb with softly hairy, whorled leaves. Later collections from Amazonas, Huánuco and Machu Picchu place it in wet montane forest from roughly 900 to 2400 m, often in moss at the forest edge.
Where it grows wild
Wet montane forest on the eastern Andean slope, growing on steep rock faces and in moss or leaf mould at forest edges in wet places. A 1964 label from Bongará (Amazonas) reads 'terrestrial in moss or leaf mold at edge of forest in wet places'; the type came from forest near the Río Yanamayo on the Pillahuata (Kosñipata) route in Cusco.
Specimens record 2200–2400 m (type, Cusco), 1820 m (Bongará, Amazonas) and 875 m (Huánuco–Tingo María road); Machu Picchu records sit around 2000–2400 m. Our measured data file has five records but no usable elevations.
