Ovary synascidiate zone

C) Stamen filament bases in five antesepalous triplets, transition from symplicate to synascioliate zone of the ovary at the level of the placentae. (D) Synascidiate zone of the ovary. (E) Floral base, with five antesepalous nectariferous depressions. Scale bar (A)-(E) = 500 pm. 

Symplicate zone. (E)-(G) Style. (G-H) Apical septum. (K)-(M) Transition between symplicate and synascidiate zone, with axile lateral placentae protruding into the locules and bearing many ovules. (M), (N) Synascidiate zone. (O) Below the ovary, five antepetalous depressions surrounded by nectariferous tissue. Scale bars = 1 mm. 

The internal compitum is continuous with the external one and extends down to the transition between the symplicate and the synascidiate zone of the ovary (Fig 8.7A-H). At the transition between the synascidiate and the symplicate zones, only one of the two margins of each carpel differentiates into an axile lateral placenta and bears a single ovule. Sometimes a locule is empty at anthesis (Fig 8.7A,...
