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 structures met with
occasionally in the leaves of cabbages, lettuces, Aristolochia,
&c. See Hypertrophy, cup-like deformities, &c.

In addition to other publications previously mentioned,
reference may be made to the following treatises on the subject
of ascidia:--Bonnet, 'Rech. Us. Feuilles,' p. 216, tab. xxvi,

1, _Brassica_; Id., 'Org. Veget.,' I, 316; 'Bull. Soc. Bot.
Fr.,' I, p. 62, _Polygonatum_; 'Bull. Acad. Belg.,' 1851, p.
591, _Rosa_; Hoffmann, 'Tijdschrift v. Natuur. Geschied.,' vol.
