Gently squeezing the cut ovary will reveal whether the placentas are united in the centre of the ovary (when the placentation is axile) or whether they just meet there without fusing (when the placentation is parietal). In a few cases the ovules are borne on the walls of a 2- or more-celled ovary; this is found particularly in the Aizoaceae. In most Cruciferae the older ovary and fruit are 2-celled, but this 30 Examining the plant is because of the development during ripening of a false septum (replum) across the ovary (see fig.

Here the ovules (one or more) arise from the base of a 1celled ovary (or rarely from the base of a solitary or free carpel, see above), as in Polygonum, Tamarix, Armeria, etc. (see fig. 3d,e,g) or are borne on a basal placental cushion (oblique in Berberis) (see fig. 3f ). (vi) Apical. In this case the ovule (generally solitary) is attached to the apex of the single cell (or free or solitary carpel, see above), as in Scabiosa (see fig.
