Wight's example of this was from Griffith in early flower ; in his picture cited he 

 guessed the colour of the flower wrong, and added a figure of a seed of some species 

 (probably) of Didymocarpus ; the figure thus concocted has defied identification until 

 Griffith's specimen in Wight's Herbarium was found.
