In botany, describing a leaf shape that combines both hastate (spear-shaped) and sagittate (arrow-shaped) characteristics, with outward-pointing basal lobes.
From Latin 'hastatus' (spear-shaped) combined with 'sagittatus' (arrow-shaped). This technical botanical term emerged in the 18th-19th centuries as botanists needed precise vocabulary for leaf classification.
Botanists created compound descriptive terms like this because nature doesn't always fit into simple categories—this word proves that sometimes you need to invent new language to capture reality accurately.
