Description

Peperomia quadrangularis is a small herby plant, often found growing on top of trees or rocks. The latin name points to the stems which are quadrangular, one to two millimetre thick, and feature tiny hairs. Leaves are elliptic, obovate, or orbicular, 10 to 22 mm wide and 12 to 30 mm long, with obtuse or only slightly pointed apex. The leaves grow typically opposite, although adventitious roots can sometimes take the place of a leaf.^[3]
