Echeveria Subrigida
''Echeveria subrigida'' is a species of succulent plant native to Mexico. It was first formally described in 1903 by Benjamin Lincoln Robinson and Henry Eliason Seaton. Its basionym is ''Cotyledon subrigida''. Etymology ''Echeveria'' is named for Atanasio Echeverría y Godoy, a botanical illustrator who contributed to ''Flora Mexicana''.Gledhill, David (2008).

Cotyledon Subrigida 138-8445
A cotyledon ( ; ; "a cavity, small cup, any cup-shaped hollow", gen. (), ) is a "seed leaf" – a significant part of the embryo within the seed of a plant – and is formally defined as "the embryonic leaf in seed-bearing plants, one or more of which are the first to appear from a germination, germinating seed." Botanists use the number of cotyledons present as one characteristic to classify the flowering plants (angiosperms): species with one cotyledon are called monocotyledonous ("monocots"); plants with two embryonic leaves are termed dicotyledonous ("dicots"). Many orchids with minute seeds have no identifiable cotyledon, and are regarded as acotyledons. The Dodders (''Cuscuta'' spp) also lack cotyledons, as does the African tree ''Mammea africana'' (Calophyllaceae). In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons form during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
