=Prolification of the embryo.=--This term was applied by Moquin-Tandon to a peculiar condition of the almond (_Amygdalus_), in which, indeed, it is not of unfrequent occurrence. In these cases one almond encloses within its cotyledons a second embryo, and this, again, in some instances, a third, the little plants being thus packed like so many boxes one within the other. The supplementary embryos are, in the ripe state at least, quite separate and detached one from another. These cases differ from the ordinary instances wherein there is an increased number of embryos in one seed in their position. In the latter case, as often happens in the seeds of the orange, the new products are placed by the side one of another.[146] For other cases of prolification or the adventitious formation of buds on leaves, roots, &c., see under Heterotaxy.
