Green Riddle's Solution

Here comes the solution to our last picture riddle: The very, very green surface on the photo is a detail of a water melon's outside.


Watermelons (or xi gua in Chinese: 西瓜, meaning northern melon) are very popular in Taiwan, as they represent a cheap, sweet and juicy refreshment in the hot summer. We saw plenty of water melon fields on the river terraces of Da-An river, where we did fieldwork lately. Obviously, these plants are not very demanding as they grow virtually on gravel only.
