vexilla

The ornithologist carefully examines the vexilla of the bird's feather under bright light.

Definition

Noun (plural of vexillum): 1. Zoology: In ornithology, "vexilla" refers to the vane or web of a feather—the flattened, often colored part that extends from the central shaft (rachis). It consists of barbs and barbules that interlock to form a smooth surface. 2. History: In ancient Rome, "vexilla" were military standards or flags carried by Roman legions or cavalry units. They were often a square piece of cloth attached to a crossbar on a pole, used for identification and signaling. 3. Botany (rare): In some botanical contexts, "vexilla" (singular: vexillum) refers to the large, upright petal of a papilionaceous flower (e.g., the banner petal in pea flowers), which serves to attract pollinators.
