In Botany
Plants with sympodial growth have a specialized lateral growth pattern in which the apical meristem is terminated. The apical meristem can either be consumed to make an inflorescence or other determinate structure, or it can be aborted. Growth is continued by a lateral meristem, which repeats the process. The result is that the stem, which may appear to be continuous, is in fact derived from multiple meristems, rather than a monopodial plant whose stems derive from one meristem only.
An example is the orchid Laelia (see illustration). The apical meristem of the rhizome forms an ascendent swollen stem called a pseudobulb, and the apical meristem is consumed in a terminal inflorescence. Continued growth occurs in the rhizome, where a lateral meristem takes over to form another pseudobulb and repeat the process. This process is evident in the jointed appearance of the rhizome, where each segment is the product of an individual meristem, but the sympodial nature of a stem is not always clearly visible.

Famous quotes containing the word botany:
“...some sort of false logic has crept into our schools, for the people whom I have seen doing housework or cooking know nothing of botany or chemistry, and the people who know botany and chemistry do not cook or sweep. The conclusion seems to be, if one knows chemistry she must not cook or do housework.”
—Ellen Henrietta Swallow Richards (1842–1911)
