De plantis: Five translated. Edited and introduced by H. J. Drossaart Lulofs and E. L. J. Poortman.

On Plants (De Plantis), sometimes attributed to Aristotle, is generally believed to have been written by Nicolaus of Damascus in the first century BCE. It is divided into two parts:

"The first part discusses the nature of plant life, sex in plants, the parts of plants, the structure of plants, the classification of plants, the composition and products of plants, the methods of propagation and fertilization of plants, and the changes and variations of plants. The second part describes the origins of plant life, the material of plants, the effects of external conditions and climate on plants, water plants, rock plants, effects of locality on plants, parasitism, the production of fruits and leaves, the colors and shapes of plants, and fruits and their flavors" (Wikipedia).
