Tragia ramosa
Desert Noseburn is a resilient, low-growing native perennial protected by microscopic, hollow stinging hairs containing histamine-like irritants. While brush contact causes a temporary stinging sensation on human skin and deters browsing cattle, this chemical defense allows it to flourish on heavily browsed rangelands. In the Hill Country ecosystem, its extensive root system binds thin limestone topsoil on dry slopes, while its foliage serves as a host plant for native checkerspot butterflies and provides dense cover for ground lizards.
