8.54 TS of the fruit of the dicotyledon Cucurblta<br />
(cucumber). This develops from an inferior syncarpous<br />
o"ary of three: fused carpels with parietal placentae (I). The<br />
numerous seeds (2) are enclosed in a pulpy parenchymatOus<br />
endocarp; this is surrounded by the firmer flesh of<br />
the mesocarp (3) in which a ring of bicollatcral vascular<br />
bundles (d., 6.11) occurs. The epicarp forms the green skin<br />
