However, it is not easy to find coherent and fully general definitions.

It now is rarely used for such objects as stems or inflorescences in general. The modern trend is towards usefully distinguishing the definition of 'scape' from those of related, but more general, terms such as Peduncle (botany) and inflorescence. Practical definition Amaryllis belladonna, its scape emerging directly from the bulb immediately underground For example: 'A leafless floral axis or peduncle arising from the ground, as in Cyclamen'. Some older usages simply amount to a stem or stalk in general, but modern formal usage tends to favour the likes of 'A long flower stalk rising directly from the root or rhizome', or 'a long, naked, or nearly naked, peduncle, rising direct from the base of a plant, whether 1- or many-fid.' Other authorities refer to the scape rising directly from the ground, without morphological analysis. The word scape (Latin scapus, from Greek σκᾶπος), as used in botany, is fairly vague and arbitrary various sources provide divergent definitions. The scapes of scallions, chives, garlic chives, and garlic are used as vegetables. Typically it takes the form of a long, leafless flowering stem rising directly from a bulb, rhizome, or similar subterranean or underwater structure. In botany, a scape is a peduncle arising from a subterranean or very compressed stem, with the lower internodes very long and hence few or no bracts except the part near the rachis or receptacle.
