While on a recent camping trip in the central mountain range of Taiwan, I came across these plants. The first was bush-like, about 2 meters high and about as wide. The striking feature was the fruit / berries found on it. The ripe ones, red in color, looked very much like cherry tomatoes. What I assume to be three stages of fruit development can be seen in the second photo (green, yellow, and red).
There is an additional photo of another plant in bloom.
If anyone knows either of these, I’d like to know the name.
