Arabis glabra (L.) Bernh. (=Turritis glabra) Tower Mustard

Essex Status: Extinct native. A biennial crucifer to 120cms, hairy only below, stem leaves entire, sagittate and amplexicaul at the sessile base. Flowers yellowish/greenish white. A colonist of open disturbed ground on light, sandy, calcareous infertile soils, that has declined throughout its range in Britain from 61 hectads post 1950 to only 19 in 1999. In the Breckland, however, it has in recent years become explosively successful at a few sites, giving rise to colonies of thousands of plants. It is yet another plant however, that has recently been transferred to the Red Data Book (Wiggington 1999) and is now the subject of a Back from the Brink project. Although not uncommon in Gibson's day, it has not been seen in Essex since 1953. However, with thriving colonies not too far away on the Suffolk breckland, it would not be surprising if it reappears sometime in Essex on the calcareous brickearths of the Tendring plateau. |
