Linnaeus was a renowned Swedish botanist who is widely known for his contributions to the field of taxonomy. He is credited with the development of the binomial nomenclature system that is still in use today. Linnaeus wrote several books during his career, but one of them was not written by him.

Book not written by Linnaeus:
- Historia Plantarum: This book was not written by Linnaeus. It was written by a Swiss botanist named Conrad Gesner in the 16th century. The book contains information on plants and their medicinal properties. It is considered to be one of the earliest works on botany.

Books written by Linnaeus:
- Systema Naturae: This book was first published in 1735 and went through several editions. It is considered to be Linnaeus's most significant work. The book introduced the binomial nomenclature system for naming organisms, which is still used today. It also classified organisms into different categories based on their characteristics.
- Species Plantarum: This book was published in 1753 and was the first to use the binomial nomenclature system for naming plants. It describes over 7,000 species of plants and is considered to be the starting point for modern plant taxonomy.
- Genera Plantarum: This book was published in 1737 and is a classification of plants based on their reproductive structures. It introduced the concept of "sexual systems" that are still used in plant classification today.

In conclusion, Linnaeus wrote several books during his career, but Historia Plantarum was not one of them.

Historia Plantarum was a book written by Theopraustus. Theophrastus described plants by their uses, and attempted a biological classification based on how plants reproduced.
The other three books, Systema Nature, Species Plantarum and Historia Plantarum were written by Carl Linnaeus to attempt and explain biological classification and scientific nomenclature.
