Pisiforma

Pisiforma is a term encountered in scientific nomenclature to denote a pea-like or pea-shaped form. It is not widely used as a formal taxonomic name in modern classifications, but it appears in descriptive morphology and in historical taxonomic literature.

In anatomy, the pisiform bone is a small, pea-shaped carpal bone located on the ulnar side of the proximal row of wrist bones. The adjective pisiforma can be found in older anatomical texts as a descriptor for features that resemble a pea in size or shape, rather than indicating a separate anatomical structure.

In botany, Pisiforma is rarely used as a formal genus name in current classifications. When the term appears, it generally serves as a morphological descriptor for seeds, fruits, or pods that are notably pea-like, without implying close relation to the genus Pisum. Its status as a formal genus name is not established in major contemporary plant databases, and it may occur as a historical or provisional designation in some publications.

Taxonomy and nomenclature: If Pisiforma is encountered as a taxonomic name, it should be verified against primary sources and authoritative databases. In many contexts, the term functions more as a descriptive epithet than as a defined taxon, and practical use may vary across disciplines and over time.
