The two foregoing cases are particularly interesting, because botanists formerly thought (see for instance Lecoq, De la Fécondation et de l'Hybridation Hybridation 1845 page 61) and Lindley Vegetable Kingdom 1853 page 436) that all the members species of the Fumariaceæ were specially adapted for self-fertilisation.

Corydalis lutea, (do), a covered-up plant produced (1861) exactly half as many capsules as an exposed plant of the same size growing close alongside. When humble-bees visit the flowers (and I repeatedly saw them thus acting) the lower petals suddenly spring downwards and the pistil upwards; owing this is due to the elasticity of the parts, when as soon as the coherent edges of the hood are sp separated by the entrance of an insect.
