The oxydocarp ( Latin cremocárpium , from other Greek: κρεμαννύω - “suspend” and καρπός - “fruit”) is a dry two-seeded fractional fruit , which is a specific schizocarpius . It is characteristic mainly for plants of the Umbrella and Araliaceae families .
The ovary is developed from a double- ovary ovary , consists of two mericarpids (semi-inflated), formed from the carpels of the ovary. Semifloods hang on karpofora - a fork forked in two, which is a fused ventral region of two carpels. At the top of the carpels, there is a stylopodia ( pillar ) - a modified nectary bearing two stylodia at the apex.
As a rule, upon reaching maturity, the mesentery of the ovum is free to hang on the carpophore, which decays along a commissure . In berula, the carpophore during ripening of the fetus does not separate from the semi-fruit and they remain fastened. Only one of the merikarpis develops in lagenius . One merikarpy also develops in the thorn bearing , which grows together with the pedicels of the stamen flowers surrounding it and the bed of the inflorescence.
