The epicalyx is the additional whorl made up of involucre that is places exterior to the whorl of the calyx. It is found in Hibiscus rosa-sinensis.

A. Calyx is the whorl made up of sepals. It is generally present in complete, perfect and imperfect flowers.
B. Involucres are the units of epicalyx.
C. Epicalyx is the additional whorl present exterior to the calyx.
D. An obdiplostemonous layer is the layer of stamens with the outer layer of stamens opposite to the petals.
Hence, the correct answer is 'Epicalyx'

Epicalyx occurs in

  1. Cycas

  2. Jowar

  3. Nephrolepis

  4. China Rose


Correct Option: D
Explanation:

The flowers belonging to the family Malvaceae have a number of bracteoles that can vary from three bracteoles to many bracteoles. These bracteoles form a whorl of epicalyx below the calyx. So, epicalyx becomes the outermost accessory whorl. It can be seen in China Rose. 

So, the correct answer is 'China Rose'

A. The condition of free petals is called polypetalous.
B. The condition of fused petals is called gamopetalous.
C. The condition of fused tepals is called polyphyllous.
D. The condition of free tepals is called gamophyllous.

In Solanum nigrum, the gamopetalous corolla is

  1. Rotate

  2. Tubular

  3. Campanulate

  4. Globose


Correct Option: A

  1. Campanulate

  2. Urecolate

  3. Rotate

A. Bell-shaped corolla is called campanulate, e.g., Campanula.
B. Urn-shaped corolla is called urecolate, e.g., Bryophyllum.
C. Wheel-shaped corolla is called rotate, e.g., Calotropis.
D. Funnel-shaped corolla is called infundibulum, e.g., Petunia.
