The latter, how. ever, were composed of metamorphosed and fleshy floral whorls. He adds, however, that cork-cells were formed abundantly on the outside of the apples; remarking, " It would seem, therefore, that with the lack of development in the inner series of whorls necessary to the perfect frnit, those which remained were liable to take on somewhat the character of bark structure " (Proc. Acad. Nat. Sc. Phil., 1873, p. 99)..
