Melastomatid weed (Miconia calvescens) is an invasive plant. It is a native of Centeral and South America and was first detected in Hawaii in 1990.
This is one of the worst invasive plants in Hawaii, where it is commonly referred to as the "purple plague", and threatens to destroy entire ecosystems.
