stabförmige

Stabförmige is a German adjective used to describe an object or organism that has a rod-like shape: elongated, cylindrical, and typically straight or gently curved. The term is applied across disciplines such as biology, botany, zoology, geology, paleontology, and materials science to denote a form that resembles a rod or baton.

The word combines Stab, meaning rod or staff, with the suffix -förmig, meaning shaped. As an adjective, stabförmige agrees with the noun it describes (for example, stabförmige Zelle for a rod-shaped cell). In practice, the term serves as a general descriptor and is often complemented by more specific morphology terms depending on context.

In biology and medicine, stabförmige morphology is used to describe cells, spores, or organisms that appear rod-like. In microbiology, the term stäbchenförmig (rod-shaped) is more common for bacteria, and stabförmige is sometimes used in broader or less formal descriptions of rod-like forms. In botany and paleontology, pollen grains, seeds, and fossilized remains may be described as stabförmig when elongated and cylindrical. In materials science, the descriptor is used for elongated particles such as nanorods or microrods, where shape influences properties and applications in catalysis, electronics, or composites.

Compared with related terms, stabförmig implies a straight, cylindrical profile, whereas fadenförmig refers to thread-like shapes and spindelförmig to spindle-like forms. Overall, stabförmige descriptions help convey a concise sense of an object’s basic geometry in scientific observation and communication.
