I found this berries at my previous vacation on Mount Lawu, they spread along with Raspberries. I don't know what kind of berry they are but they are bigger than raspberries, almost the same size as strawberry. They have sour taste but not so juicy :whistle:

I picked some of the fresh-looking berries and ate them, very tasty. After eating ten or more berries, my stomach were fulfilled :yes:

See two more photos at my Wild Berries photo album. :yes:
