Century Dictionary and Cyclopedia
- n. In botany, the act of budding; also, the manner in which a young leaf is folded up in the bud before its unfolding.
- n. In zoology, the process of reproduction by buds; the formation of a new individual by the protrusion and complete or partial separation of a part of the parent; budding. Gemmation, when complete, is a kind of fission, but the part budded is commonly small in comparison with the size of the parent.
- n. Also called gemmulation.
- n. The arrangement or phyllotaxy of leaf-buds.
GNU Webster's 1913
- n. (Biol.) The formation of a new individual, either animal or vegetable, by a process of budding; an asexual method of reproduction; gemmulation; gemmiparity. See Budding.
- n. (Bot.) The arrangement of buds on the stalk; also, of leaves in the bud.
- n. asexual reproduction in which a local growth on the surface or in the body of the parent becomes a separate individual
“In addition to these buds containing germinal elements alone, there is another which illustrates the process of "gemmation" -- i.e. the direct out-growth of a fully formed offspring.]”
“Machinery Hall has illustrated, from its earliest days, the process of development by gemmation.”
“Stravadium has very minute stipules, the habit and gemmation is that of”
“Therefore in many of such lower organisms such a congeries of ancestral gemmules must exist in every part of their bodies, since in them every part is capable of reproducing by gemmation.”
“That such a complete collection of gemmules is aggregated in each ovum and spermatozoon in most animals, and in each part capable of reproducing by gemmation (budding) in the lowest animals and in plants.”
“The lichens have a very peculiar method of gemmation.”
“Originally, in the earlier ancestral types, reproduction was effected by fission or gemmation (simple division or budding), without any necessity for conjugation with another individual of the species; and reproduction by gemmation corresponds to the processes of detumescence, to the ejaculation of the spermatozoa by the male.”
“Successive births do not mean transmigration in the common sense of that word, but only the self-propagation of  Karma: the perpetual multiplying of certain conditions by a kind of ghostly gemmation, -- if I may borrow a biological term.”
“We have reason, from comparative anatomy and ontogeny, to believe that it multiplied by sexual generation, not merely asexually (by cleavage, gemmation, and spores), as was no doubt the case with the earlier ancestors.”
“This brood is again wingless, and it proceeds at once to bud out several generations more, by internal gemmation, as long as the warm weather lasts.”
