The flowers form a tiny white cluster in the axils of the leuf-.-^tocks, and these turn to greenish-white herries with meridian lines. The berries stay on the plant all winter and any part of the plant is jxiisonous if broken. The usual poison is, n<» doubt, from shoe laces which have strii)ped off the leaves in passing through them, and the hands thftt luce the shoes transfer the jjoison to the face. The poison is insoluble in water and so washinn only spreads it. The hands should be washed in methylated spirits, strong soap or hyp./ *uli)hite of soda usetl in iihotoRraphy.
