Which North Eastern State in India is also known as 'Paradise of Botanists' ?

Concept

In Indian geography General Awareness, a state earns a nickname like "Paradise of Botanists" when it is the single state most strongly associated with an exceptional natural feature -- here, outstanding plant diversity and endemism that draws botanical study.

Application

Arunachal Pradesh lies almost entirely within the Eastern Himalaya biodiversity hotspot. Its recorded flora includes several thousand species of flowering plants and several hundred orchid species, many endemic to the state -- the scale of diversity that earned it both the title "Paradise of Botanists" and the separate nickname "Orchid State of India".

Cross-check

Checking the other North Eastern states against the same epithet confirms the choice:

• Mizoram is known for its high forest cover and bamboo-dominated hill forests, not for a botanist-specific title.

• Manipur is popularly called the "Jewel of India" or "Switzerland of India", and hosts the endemic Shirui Lily on one hill range -- a narrower, single-species distinction rather than a state-wide botanical reputation.

• Nagaland is best known for its tribal and cultural diversity (celebrated at the Hornbill Festival) rather than for a botanical epithet.

Only Arunachal Pradesh carries the specific, widely-cited "Paradise of Botanists" title, confirming it as the correct answer.
