bulbous

This term describes a specific type of roundedness that implies a swelling or protrusion from a central point. It is more descriptive than "round" or "spherical," as it suggests a shape that is slightly distorted or enlarged, often resembling the organic growth of a plant bulb.

When applied to human features, particularly the nose, the word often carries a slightly caricatured or descriptive tone. While not inherently negative, it emphasizes a prominent, rounded protrusion that can suggest a specific character type, such as a jolly or eccentric persona, rather than a classically symmetrical shape.
