The structure of the pistil (Figs. 47, 48), however, issomewhat different. On making a cross-section throughthe young apple, five cells containing the unripe seedsare seen radiating from the centre. These seed-vesselsare imbedded in a fleshy mass, the outer limit of whichis marked by a circle of green dots, and outside thesedots is the flesh which constitutes the eatable part ofthe apple. The inner mass, whichencloses the core, belongs to the re-ceptacle, whilst the outer edible por-tion is the enlarged calyx. At the endopposite the stem will be found thepersistent calyx-teeth. We have inthis flower, therefore, a sij7icarpoitspistil of five carj)els, instead of anapocarpous one, as in Sweet-Brier. C
