The bark, in goiug beyond each leaf or whorl of leaves, 

 envelops the whole stem, as shown in diagram. Fig. 14(3. 



In the apple, pear, banana, prickly pear, melon, and hundreds 

 of others, in whic-h the ovary is inferior, the fruit envelope is the 

 b'ark, and in the banana and prickly i)ear it can be peeled off a.s 

 readily as one can peel the bark off any green stem. The leaves 

 in the ease of an inferior ovar}, oi- what correspond to leaves — 

 sepals, petals, stamens — are given off from the ri<lge surrounding 

 the apex of the fruit, as shown in diagram, Fig. 147.

 the orange ovary pushed beyond 

 the floral leaves and covered 

 with hark. 



Xow, in the orange it is po-^sible that the peel is al.so a 

 continHafInn of the bark, with this difference, viz., that the ovary, 

 unlike that of the jm'.-ii-, is pushed up bei/onfl Xhr floial leaves, the 

 bark followiuir it, as it would follow the stem bevoml ordinarv 

 leaves, the disk proper being only a fohl of the bark under the 

 ovarv, repres«^nting a suppressed phyllous whorl, as shown in 

 diagram. Fig. 148.
