The term "crustaceous" in literature is often employed to evoke an image of a thin, dry, and brittle surface, lending a tactile quality to the description. For example, Tavera’s account in "The Medicinal Plants of the Philippines" uses the term to characterize the testa of seeds, highlighting its delicate yet distinctly hardened layer by describing it as "thin and crustaceous" [1]. This usage serves to emphasize the visual and textural nuance of the subject, inviting readers to appreciate the contrasting traits of vulnerability and resilience found in nature.
