The constitutional tendency to fleshi-ness, which is the characteristic of the Pear, is not lost, in thisor either of the two other cases, but is preserved throughout,only diminishing towards the Fig. XXI. Transformed Pears. Fig. XXII. In Fig. XXII. the phenomena take a somewhat differentdirection, the leafy tendency being greater in some of thesepals, but the tendency to acquire succulence having beenpreserved in a far greater degree; as if the disturbing cause,whatever it may have been, which originally prevented theyoung parts from becoming petals, &c., and which forced thecentre to lengthen like a branch, was effectually withdrawnand overcome by the tendency to become succulent, whichthe parts had already acquired, when the disturbing causebegan to act. 88 FEUIT BBANCHES.
