reniform
Reniform is a technical adjective used almost exclusively in scientific, medical, or academic contexts. While it means the same thing as kidney-shaped, using reniform signals a professional or scholarly register. You will encounter it in botanical descriptions of leaves, anatomical reports of organs, or geological descriptions of mineral formations.
In casual conversation, a native speaker would almost always use kidney-shaped. Using reniform in a non-scientific setting would sound overly formal or pretentious. It is a descriptive term of morphology and does not carry emotional connotation, whether positive or negative.
When used in botany, it specifically describes a leaf that is wider than it is long, with a notch at the base where the petiole attaches, mimicking the curved silhouette of a human kidney.
