- n. In botany, a term proposed by Engelmann for the separation of floral whorls or of parts from each other by the unusual elongation of the internodes.
“The adjacent figure of a monstrous _Delphinium_ taken from Cramer illustrates well the elongation of the floral axis and the apostasis of the carpels.”
“Among _Rosaceæ_, the change in question is very common, especially in conjunction with an elongation of the axis of the flower (apostasis) and with prolification, though it is by no means always co-existent with these malformations.”
“This is borne out by the frequency with which apostasis, or the separation of the floral whorls one from another, to a greater degree than usual, is met with in prolified flowers.”
“-- Flower of _Delphinium_, showing apostasis of carpels, from lengthening of the thalamus, &c.”
