“While most of us would be familiar with the widespread Sendudok shrub (Melastoma malabathricum), we may not be entirey aware of its intricate pollination process. The principal pollinators are Carpenter Bees (Xylocopa species), which give the flowers a good buzz with each visit.
“The Big Black Carpenter Bees (Xylocopa latipes) are probably the most frequent and prominent visitors (above-below).
“The Black and Yellow Carpenter Bee (Xylocopa aestuans) is also a regular (below).

“If we take a closer look at the Sendudok flower, we can observe two distinct types of stamens. This is known as stamen dimorphism (Luo et al., 2008). A detailed explanation of these different stamens may be found HERE.
