  Advantage & Disadvantage of Classification of Plants

Advantages of Bentham and Hooker's classification of plants:

1. Bentham and Hooker's classification is the mainly natural system, relies on actual examination of specimens.

2. The explanation of plants is fairly accurate and reliable.

3.  Like it is easy to follow, it is employed as a key for the identification of plants in Kew herbarium and various other herbaria of the world.

4. Even though this system is natural, most of the features of this system depict affinity to modern concepts of evolution.  For instance, the order Ranales that is the first order in the arrangement of plants, has been provided a primitive position in this system. Recent taxonomic locating also point out that the members of Ranales are the most primitive living angiosperms.

5. The position of monocotyledonae after the dicotyledonae as well appears to be in accordance with the evolutionary trends.

Disadvantages of Bentham and Hooker's classification of plants

1. The position of Gymnospermae in between dicotyledonae and monocotyledonae is an error.

2. Various significant floral characters have been neglected in this system.

3. Advanced family Orchidaceae has been referred as primitive among monocotyledons and it is located in the beginning of the system.

4. In this system, a number of closely related families have been separated and located under dissimilar groups. 

For instance, all the families of series Curvembryeae, of Monochlamydeae related to Caryophyllaceae of series Thalamiflorae of Polypetalae, but they are detached.

5. Not related families have been grouped nearer. For instance, Podostemaceae of series Multiovulatae aquaticae of Monochlamydeae justifies a place in Rosales of the series Calyciflorae of Polypetalae. Likewise Laurineae of series Daphnales of Monochlamydeae justifies a place in Ranales of the series Thalamiflorae of polypetalae.  So, two not related families Podostemaceae and Laurineae are grouped nearer.
