Century Dictionary and Cyclopedia
- n. The seed-lobe or rudimentary leaf of the embryo in plants. There may be only one, as in all monocotyledonous or endogenous plants, or two, as in nearly all dicotyledonous or exogenous plants, or several in a whorl, as in most Coniferæ. In many cases the cotyledons are large as compared with the rest of the embryo, being a storehouse of nourishment for the young plant in its earliest stage of growth, or they may be small, as in most albuminous seeds, in which the albumen is a supply of food. The arrangement of the cotyledons within the seeds is very various. The more important modifications of position are those of accumbent cotyledons, in which the radicle is laid against the back of the cotyledons, and incumbent, where it is applied to the edge.
- n. [capitalized] [NL.] A genus of plants, natural order Crassulaceæ, with very thick fleshy leaves and showy flowers. Many species are in cultivation, especially for bedding purposes, chiefly Mexican species formerly referred to Echeveria. The navelwort of Europe is C. Umbilicus.
- n. In anatomy, one of the distinct patches in which the villi of a cotyledonary placenta are gathered upon the surface of the chorion.
GNU Webster's 1913
- n. (Anat.) One of the patches of villi found in some forms of placenta.
- n. (Bot.) A leaf borne by the caulicle or radicle of an embryo; a seed leaf.

“Cotyledon_, and belongs to the alpine regions of Europe.”
“Then she led him to the back of the house and talked the incident out of his mind as cleverly as possible by giving him an intensive botanical study of Cotyledon.”
“Her cheeks flushed, her eyes brilliant, her lips laughing, Linda was showing Donald thrifty specimens of that Cotyledon known as "old hen and chickens," telling him of the rare Echeveria of the same family, and her plunge down the canyon side while trying to uproot it, exulting that she had brought down the plant without a rift in the exquisite bloom on its leaves.”
“From the first instant he had looked into her clear young eyes as she stood in Multiflores Canyon triumphantly holding aloft the Cotyledon in one hand and with the other struggling to induce the skirt of her blouse to resume its proper location beneath the band of her trousers, he had felt that her heart and her mind were as clear and cool and businesslike as the energetic mountain stream hurrying past her.”
“On the shadiest side homed most of the ferns and the Cotyledon.”
“That first day, as soon as I put down the Cotyledon safely and tucked in my blouse, I would have put my hand in yours and started around the world, if you had asked me to.”
“Linda studied the canyon with intent eyes, but bruised flesh pleaded, so reluctantly she arose, shouldered her belongings, and slowly followed the road out to the car line that passed through Lilac Valley, still carefully bearing in triumph the precious Cotyledon.”
“I fervently hoped not to break more than a dozen of my legs and arms, and was forced to bring down intact the finest Cotyledon pulverulenta that Daddy or I had found in fourteen years of collecting in California.”
“The instant I deposited my Cotyledon in a safe place I would have put my hand in Peter Morrison's and started around the world if he had asked me to go.”
“I think I am fairly well battered, but you will please to observe that there isn't a scratch on Cotyledon, and I brought her down -- at least I think it's she -- from the edge of that boulder away up there.”
