Descurainia sophia Flixweed

An annual, hairy, yellow-flowered crucifer (sometimes biennial) with pinnately divided tansy-like leaves. It occurs as a weed of arable fields or in waste places, on refuse tips and also in disturbed areas along tracks and roads where it is usually casual and rarely persists. It seems to have unddrgone a significant decline in much of Britain and it rather rare in Wales. There has only been one record in West Glamorgan in recent decades.
