Besides the above varieties of ascidia formed from the union of 

 one or more leaves, there are others which seem to be the result of a 

 peculiar excrescence or hypertrophy of the leaf. Such are some of 

 the curious pitcher-like stnictures met with occasionally in the leaves 

 of cabbages, lettuces, Aristolochia, ^. See Hypertrophy, cup-liko 

 deformities, &c.
