Scape (botany) Scape (botany) In botany, a scape is a long internode forming the basal part or the whole of a peduncle. Typically it takes the form of a long, leafless flowering stem rising directly from a bulb, rhizome, or similar subterranean or underwater structure. The scapes of scallions, chives, garlic chives, and garlic are used as vegetables. The word "scape" (Latin "scapus", from Greek σκᾶπος), as used in botany, is fairly vague and arbitrary; various sources provide divergent definitions. Some older usages simply amount to a stem or stalk in general, but modern formal usage tends to favour the likes of
Plant life-form or tree. Conversely, unrelated species may share a life-form through convergent evolution. While taxonomic classification is concerned with the production of natural classifications (being natural understood either in philosophical basis for pre-evolutionary thinking, or phylogenetically as non-polyphyletic), plant-life form classifications uses other criteria than naturalness, like morphology, physiology and ecology. "Life-form" and "growth-form" are essentially synonymous concepts, despite attempts to restrict the meaning of growth-form to types differing in shoot architecture. Most life form schemes are concerned with vascular plants only. "Plant construction types" may be used in a broader sense to encompass "planktophytes", "benthophytes" (mainly algae) and terrestrial plants.
