Here is one most of you may not know.
Known here as 五指毛桃果 (wǔ zhǐ máo táo guǒ, literally five-finger hairy peach fruit), these are Ficus simplicissima Lour., a type of Asian fig. In the local Zhuang language, they are known as 牛奶子 (niú nǎi zǐ- meaning ‘milk') because of its milky interior. It'd call it 'sap' rather then milk. It also 'bleeds' from the stems.
They are slightly sweet and, even here, kind of rare.
