Moritz Michael Daffinger, Primula veris acaulis L. (Common Primrose), around 1830–1849, watercolor, preliminary drawing with pencil on paper © Graphic Collection of the Academy of Fine Arts Vienna
A very precisely executed watercolour showing yellow, delicate primroses in the centre of the picture against a light background, together with leaves and roots at the bottom. The outer edges of the leaves show signs of withering, so the colour changes from green to brown.
