spearshaped

Spear-shaped is a descriptive term used in morphology to describe forms that resemble a spear: elongated and tapering to a sharp point. It is commonly applied to leaves and other plant parts, but can also describe objects in other disciplines. The term emphasizes the overall silhouette rather than exact dimensions.

In botany, spear-shaped leaves are longer than wide and taper toward the apex, with a base that may be rounded or slightly narrowed. The apex is typically acuminate or acute. In many field guides, spear-shaped is treated as a form within the broader category of lanceolate leaves; some sources distinguish spear-shaped from lanceolate by a more pronounced taper or a broader base, though usage varies.

The term is often used in plant identification and horticulture to convey a clear, simple image of leaf form. It is not a rigid taxonomic term, and precision can depend on the author or key. Descriptions may also reference related shapes such as oblong, elliptic, or ovate to indicate relative proportions.

Examples include iris and gladiolus, whose leaves are typically slender and pointed, and other monocots such as yucca and some agaves. In broader morphology, spear-shaped can describe any slender, pointed structure, not limited to botanical leaves.
