A Little Sour. Rumex acetosella, Sheep's Sorrel, Hortus Botanicus, Amsterdam, The Netherlands

Here are the tiny female flowers of Sheep's Sorrel growing in a sandy partch of the Hortus. The plant's leaves have a slightly sour taste - vitamin C. They were used in ancient times to alleviate the symptoms of scurvy. Various sites on the internet claim that Roman soldiers chewed those leaves to quench thirst on their long marches. Much as I looked, I couldn't find a dependable reference.
