The Coronilla (scutia buxifolia) is a stout, short and thorny tree. It is very common in the hills and riverside forest of Southern Brazil, Uruguay and Northern Argentina. It has a very slow growth rate, just 2 millimetres by year. Its wood is hard and heavy, very appreciated for firewood.
Coronilla roots are unearthing when the riverbed is low. They are used for wood-carving, especially pipe-carving. It is considered an ideal material for this issue because pipes made by coronilla lignite don’t burn, heat or crack.
