 — Foxglove {Digitalis -purpurea) is very common in New Zealand and listed in some sections 

 as a noxious weed. The usual method of eradication is by pulling, but more attention should 

 be given to cleaning up those areas of land likely to produce greatest revenue. There is evi- 

 dence to believe that on good grass lands this weed will disappear in a period of five to eight 

 years without hand pulling. — N . J . Giddings.
