What does ensate mean?
"Ensate" is an adjective describing something bristly or bristle-bearing — covered in, or armed with, stiff bristles or bristle-like hairs. The word is a technical term encountered almost exclusively in botany and zoology, where it characterizes the stems, leaves, or bodies of organisms such as thistles, certain grasses, and various insects and larvae. It derives from the Latin "ēnsātus," meaning "armed with a sword," itself formed from "ensis," the Latin word for sword; the image behind the term is of bristles standing like tiny blades along a surface. A closely related Latin descendant is "ensiform," meaning sword-shaped. Because "ensate" belongs to the specialized vocabulary of descriptive biology rather than everyday speech, it carries no emotional connotation and appears mainly in field guides, taxonomic descriptions, and scholarly writing. Writers seeking a precise alternative to "bristly" or "setose" will find "ensate" an exacting, if rare, choice.

'Ensate' comes from the Latin word for sword — so a bristly plant is, quite literally, armed.

Etymology of ensate
"Ensate" derives from the Latin "ēnsātus," meaning "armed with a sword," formed from "ensis," the classical Latin word for sword. The term entered English as a learned borrowing, likely in the early modern period, and settled into technical use in botany and zoology to describe bristled structures. Its closest English relative is "ensiform" (sword-shaped), which shares the same Latin root.
How ensate is actually used
A rare technical term used chiefly in botany and zoology; unlikely to be encountered outside scientific descriptions of hairy or bristled organisms.
