“Botany, the eldest daughter of medicine.” – Johann Hermann Baas
Botany is one of the optional subjects that the UPSC offers candidates in the mains exam. Not many candidates opt for it as it is a specialized subject. However, there have been a few toppers who had taken this optional subject (Gopala Sundera Raj, AIR 5/2011). This article talks about Botany as an optional for the IAS mains exam and gives a few tips to prepare for this optional.

Candidates who have taken Botany or Biology as their graduation major and are in touch with this subject can take this optional. Candidates who have lost touch but still like the subject or enjoy reading about it can select this subject.
Also, aspirants with a background in biotechnology can also opt for this optional subject.
