•One cell initiation and lysigenous oil cavities may be common in Dictamnus.•Lysigenous formation of the secretory cavities in D. dasycarpus is a PCD process.•Clusters of cells from a protoepidermal cell undergo different cell death fates.•Degradation products in the oil cavities may be used for the...
