English: Climbing Corydalis A delicate little climbing plant, Ceratocapnos claviculata (formerly Corydalis claviculata) is growing here in a damp area of tussocky moor and woodland near New Waste. In 1874, W. E. HART wrote in "Nature": "A sprig placed in a glass of water and out of the way of insects continues to grow and to bear flowers and fruit with nearly as much regularity as if still rooted to its native bank. The flowers do not gape spontaneously; and, as most of the older ones that I have examined in a state of nature have their lips depressed, I think it certain evidence of the agency of insects, though I have not yet been so fortunate as to witness their operations." http://www.nature.com/nature/journal/v10/n242/abs/010125b0.html
