drieaderige

Drieaderige is a Dutch adjectival term describing objects or structures that possess three veins or channels. The word is formed from drie (three) and ader (vein, vessel) with the adjectival suffix -ige, yielding a meaning akin to "three-veined" or "three-vascular." It is used primarily in scientific Dutch texts and in fields such as botany and anatomy. The term is descriptive rather than classificatory and is commonly found in observational notes, descriptions, and illustrations.

In botany, drieaderige describes leaves or leaf-parts with three principal veins that originate near the base of the leaf and extend into the blade. This venation pattern is one of several leaf-venation types and can help distinguish certain species or varieties, though it is not exclusive to a single taxon.

In anatomy or physiology, the term may describe a structure with three main venous channels or vessels, such as in descriptive anatomy or comparative anatomy. The usage is specialized and more common in Dutch-language sources than in English-language texts.

Spelling and variants: the term may appear as drieaderige or drie-aderige depending on hyphenation conventions; some texts prefer "drie-aderig" as the attributive form. The concept has no widely used English exact equivalent beyond descriptive phrases like three-veined.
