Weeds of New Zealand And How To Eradicate Them

by F W Hilgendorf

2nd edition, published 1937. Hardback bit worn on cover as you can see in image. But otherwise in good condition. 

What is a weed through to classifications of weeds and what to do about them. With black and white illustrations and photo 'micrographs' of weed seeds. Fantastic book. FW Hilgendorf was born in Otago in 1874 and was a teacher and agricultural scientist of some acclaim.
