Cropped image of the above
Here's what I t think I can see;
Flowers with five corolla lobes / petals fused (sympetalous), seems there is shallow corolla tube. There are 5 stamens attached generally near the base of the corolla tube and are alternate to the corolla's lobe, so it will be positioned in between each petal lobes. The anthers are short with slender filaments. The stigma is very short and broad (or seems lobed-unclear in photos).
There are five persistent small sepals, that persist after petals falls off.
Those morphology are consistent with Viburnums
The leaves are unclear whether they are opposite or alternated, but the venation and margins are also consistent to Viburnums
