This plant that over-runs old cultivations and grazing land was introduced into Antigua as a fuel for the sugar industry of the 18^th century. It is a fast growing hardwood with a high calorific value. It has made itself very much at home here, producing thorny thickets. In spite of its uncomfortable prickles it has had many uses: perfume, ink, dye, glue, tanning, tool handles and charcoal.
