Term Definition
Cotyledons Seed leaves, i.e., the embryonic leaves. Cultivated seedling of Couroupita guianensis.   Photo by S. A. Mori.
Cotyledons absent (= embryo macropodial) A massive embryo that shows no obvious cotyledons. Cotyledons absent. Photo by S. A. Mori
Cotyledons bowed Referring to cotyledons that are arched in such a way that they form an air chamber thought to aid in dispersal, either by the wind or by water. Bowed cotyledons and seed air chamber of Allantoma integrifolia. Photo S. A. Mori.
Cotyledons cryptocotylar Cotyledons that remain within the seed coat at germination. In the Lecythidaceae the seed coat is thin and fragile and breaks apart as the embryo increases in size. Cryptocotylar seeds of Lecythis prancei. Photo by S. A. Mori.
Cotyledons epigeal At germination the cotyledons emerge from the seed coat above the ground. Seedling of Lecythis tuyrana. Photo S. A. Mori.
Cotyledons fleshy, irregular (= cotyledons plano-convex) Seed leaves (= cotyledons) that are fleshy and irregular. Sectioned seeds of Gustavia augusta showing fleshy cotyledons. Photo by S. A. Mori.
Cotyledons foliaceous (= cotyledons leaf-like) Cotyledons that look like leaves but differ in their opposite instead of alternate attachment. Same as cotyledons leaf-like which is the preferred term. Seedling of Cariniana micrantha. Photo by S. A. Mori.
Cotyledons hypogeal A type of seed germination in which the cotyledons are retained below the ground. Seed germination of an oak tree. Photo by C. A. Gracie.
Cotyledons leaf-like (= cotyledons foliaceous) Cotyledons that look like leaves but differ in their opposite instead of alternate attachment. Seedling of Cariniana micrantha. Photo by S. A. Mori.
Cotyledons phanerocotylar A type of seed germination in which the cotyledons emerge from the seed coat at germination.. Seedlings of Gustavia hubbardiorum. Photo by X. Cornejo.
Cotyledons plano-convex (= cotyledons fleshy, irregular) Same as cotyledons fleshy. We no longer use plano-convex because the cotyledons are very irregular and are not plano-convex as in, for example, the embryo of species of Gustavia. Mature fruit of Gustavia augusta. Photo by C. Galdames.
Embryo macropodial (= cotyledons absent) Massive embryo that shows no obvious cotyledons. Cotyledons absent is the preferred term. Cotyledons absent. Photo by S. A. Mori
Isocotylar cotyledons Cotyledons that are morphological identical Seedling of Cariniana micrantha. Photo by S. A. Mori.
