Prof. John M. Coulter, in The Dial: "Prof. Kerner has brought the most recent researches within reach of the intelligent reader, and in a style so charming that even the professional teacher may learn a lesson in the art of presentation.... It is such books as this that will bring botany fairly before the public as a subject of absorbing interest; that will illuminate the botanical lecture-room."
Prof. Chas. R. Barnes, in The Botanical Gazette: "This lucidity, and the excellent illustrations, not only will introduce the non-botanical reader to the science of botany, but should serve as a lesson to the professional botanist in the art of presentation."
The Nation: "He has succeeded in constructing a popular work on the phenomena of vegetation which is practically without any rival."
