The length of ray floret.
In my photo of Ray floret, the blade is 15 mm, and the floret stalk is 7 mm. So, the ray floret length is 22 mm or 15mm? This information is important to distinguish between four candidates, namely Delairea odorata, Senecio angulatus, Senecio tamoides, and Senecio macroglossus.

Kindly identify this plant.
Date/Time- 15 FEB 2021
Location-Place, Altitude, GPS- Bengaluru
Habitat- Garden/ Urban/ Wild/ Type- Balcony Garden
Plant Habit-Tree/ Shrub/ Climber/ Herb- Climber
Height/Length- Grown up to 100 cm tall.
Flowers are not fragrant. Most of the flowers have five ray florets.
-----
The yellow flowers are difficult to identify.
My reasoning:
My flower has five ray florets. So, it cannot be Delairea odorata (no ray florets).
The ray floret blade length is 15 mm. It is medium. So, it cannot neither be a small blade (6-9 mm) flower of Senecio angulatus nor be a large blade (>20mm) flower of Senecio macroglossus.
So, by eliminating all the possibilities one can safely reason out that the flower is Senecio tamoides.
-----
Other observations from 'Comparison' photo.
The flower in question has bracts longer and not curling away. There is a presence of pappus between the bract whorl and ray floret whorl.
-----
Now I invite all experts to confirm the flower.

So it is indeed Senecio tamoides.
