It's Malabar Melastome, The Indian Rhododendron!

Malabar melastome or the Indian Rhododendron is often confused with the Purple Glory. The former is botanically known as Melastoma malabathricum, whereas, the later is known as Tibuchina granulosa.

Both are belonged to Melastomataceae family. The stem, leaf and flower are almost look similar between these two species, but they have clear difference for stamen.

In case of Melastoma malabarthricum, stamens are yellow in color, and filaments are shorter compared to Tibuchina granulosa. The stamens of Tibuchina are white colored, with longer filament.

From archive of 2007, the wild marigold from Busan, Korea

While captured in 2007 at Pusan National University, Busan, South Korea, I recognized its botanical family, as Asteraceae by its leaf structure and floral biology. It is some kind of marigold, but no one could confirm the name of flower then. 

The picture has been stored in my hard disk, and recently came to the surface while I was looking for some old photos of my elder kid. Now, with the help of Google Lens, ID of plant is confirmed. Its indeed a marigold!
