Question

In which book Bentham and Hooker proposed their classification?
A. Genera Plantarum
B. Species Plantarum
C. Historia Plantarum
D. Historia Nature

Answer 1

Hint: G. Bentham and J.D. Hooker were British scientists.
They had published a book which contained a system of botanical taxonomy or classification.

Complete answer: George Bentham and Joseph Dalton Hooker, the British botanists were associated with the Royal Botanic Gardens, in England.
They had put forward a system of botanical taxonomy.
The system was based upon the principle of natural affinities.
In the book called 'Genera Plantarum', Bentham and Hooker gave a comprehensive system of classification of seed plants, and it is regarded as the most convenient system of classification because of its practical utility.

So, the correct answer is A. Genera Plantarum.

Note: The system has been considered as ‘pre-Darwinian’ because it does not take evolution into account. It was published much before the existence of internationally accepted rules of botanical nomenclature.
Hence, "ordo" indicates a family; "cohors" indicates an order, in the first two volumes. "Series" also indicates an order in the third volume while it refers to rank above that of order in the first two volumes.
