Question

Scientific name of Amaltas (Golden shower tree) is-

• A. Bombax malabaricum
• B. Cassia fistula
• C. Butea monosperma
• D. Delonix regia

Hint:

Cassia fistula, known for its vibrant yellow flowers, is a tropical tree commonly used in ornamental gardening.

Answer 1

The Correct Option is B

Each option is a well-known Indian flowering tree distinguished mainly by flower color: semal (Bombax) is red, palash (Butea) is orange-red, gulmohar (Delonix) is red-orange, and Cassia fistula is the one known specifically for golden-yellow flower clusters, which is exactly the Golden Shower Tree/Amaltas described in the question.

Since color is the deciding clue and only Cassia fistula matches "golden," it is the correct scientific name.

Therefore, the correct answer is Cassia fistula.

Answer 2

Recalling the common Hindi/English name tied to each scientific name is another route to the same answer.

1. Bombax malabaricum: Commonly called semal or silk-cotton tree, a name with no link to the golden shower/Amaltas description.
2. Cassia fistula: Commonly called Amaltas in Hindi and the Golden Shower Tree in English, directly matching the tree named in the question.
3. Butea monosperma: Commonly called palash or dhak, unrelated to the Amaltas name.
4. Delonix regia: Commonly called gulmohar, again a different tree from Amaltas.

Only Cassia fistula carries the common names Amaltas and Golden Shower Tree used in the question.

Therefore, the correct answer is Cassia fistula.
