Gemmation

Definition and stakes

William Abbott Herdman,  1911 Encyclopædia Britannica (1911)

“ Many of the forms reproduce by geminmation, and in most of them the sexually-produced embryo develops into a tailed larva.
The Ascidiacea includes three groups—the simple Ascidians, the compound Ascidians and the free-swimming colonial Pyrosoma.
Sub-Order I.—Ascidiae simplices.
Fixed Ascidians which are solitary and very rarely reproduce by gemmation; if colonies are formed, the members are not buried in a common investing mass, but each has a distinct test of its own. No strict line of demarcation can be drawn between the simple and the compound Ascidians, and Simple Ascidians.

Andre Norton,  Plague Ship (1956)

“ He knew the technical analysis of the gems—that they were, as the amber of Terra, the fossilized resin exuded by ancient plants (maybe the ancestors of the grass trees) long buried in the saline deposits of the shallow seas where chemical changes had taken place to produce the wonder jewels. In color they shaded from a rosy apricot to a rich mauve, but in their depths other colors, silver, fiery gold, spun sparks which seemed to move as the gem was turned. ”
