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

paper on prolification, with numerous bibliographical references.
