Formlegum

Formlegum is a hypothetical genus in the legume family created for botanical morphology and teaching. It is not part of any extant formal classification in current taxonomic treatments.

Etymology and taxonomy: The name combines Latin forma, meaning shape or form, with legumen, meaning legume, following standard Latin-based genus formation. In a didactic framework, Formlegum is placed within the plant kingdom and is used to illustrate the diversity of legume fruit forms. Taxonomically, it is described as Domain Eukaryota; Kingdom Plantae; Clade Angiosperms; Clade Eudicots; Clade Rosids; Order Fabales; Family Fabaceae; Subfamily Faboideae; Genus Formlegum (fictional).

Description: Formlegum species are depicted with typical papilionaceous flowers, pinnate leaves with 3–9 leaflets, and stipules. The fruit is a dehiscent legume pod, and seed size and color vary among imagined species to demonstrate the range of legume seed morphology. In this construct, leaf arrangement is usually alternate, and leaf margin and venation can differ to illustrate structural variation within a single genus concept.

Species and examples: Examples used for illustration include Formlegum varians (variable form), Formlegum clavifolium (clavate leaflets), and Formlegum ligneum (woody form). These entries are hypothetical and used for comparative teaching rather than as real species.

Habitat and use: In pedagogical use, Formlegum is described across temperate to subtropical habitats with soils ranging from sandy to calcareous. The genus serves as a tool for teaching morphology, morphometrics, and evolutionary relationships within the legume family.
