High Quality Content by WIKIPEDIA articles! Capsicum pubescens is a species of the genus Capsicum (pepper), which is found primarily in Central and South America. The name component pubescens means hairy, which refers to the hairy leaves of this pepper. The plants, but especially the fruits, are often referred to as rocoto (Quechua: ruqutu) and locoto (Aymara: luqutu). As they reach a relatively advanced age and the roots lignify quickly, sometimes the familiar name is tree chili. Of all the domesticated species of peppers, this is the least widespread and systematically furthest away from all others. A very notable feature of this species is its ability to withstand cooler temperatures than other pepper plants.
