Fairly technical and advanced for the average layman, but a worthwhile overall for the botanist in its story of plant history and the strange and wonderful vegetable kingdom. It explains the effects of soil and climate, the chemical make-up and elements of plants, their life cycles, their economic importance, their classifications and their evolution. It goes further into the environmental conditions influencing plants from their primitive forms to their more advanced manifestations, it follows their migrations, domestication, and the part they play in commerce, agriculture, and gardening. Specific and specialized. Call to attention of Garden Club enthusiasts.
