ABSTRACT
Pinguicula vulgaris grows in moist places, generally on mountains. The young central leaves are deeply concave, and project upwards; the older ones towards the outside are flat or convex forming a rosette from 3 to 4 inches in diameter. That such thick, large leaves as those of Pinguicula vulgaris should have the power of curving inwards when excited has never even been suspected. In the case of Pinguicula, as soon as an insect has been pushed for some little distance towards the midrib, immediate re-expansion would be beneficial, as the margins could not capture fresh prey until they were unfolded. Pinguicula Grandiflora is so closely allied to the last that it is ranked by Dr Hooker as a subspecies. Pinguicula lusitanica species differs from Pinguicula vulgaris and grandiflora in the margins of the leaves, when excited by organic bodies, being inflected to a greater degree, and in the inflection lasting for a longer time.
