Entries linking to non-vascular
non-
a prefix used freely in English and meaning "not, lack of," or "sham," giving a negative sense to any word, 14c., from Anglo-French noun-, from Old French non-, from Latin non "not, by no means, not at all, not a," from Old Latin noenum "not one" (*ne oinom, from PIE root *ne- "not" + PIE root *oi-no- "one, unique"). In some cases perhaps from Middle English non "not" (adj.), from Old English nan (see not). "It differs from un- in that it denotes mere negation or absence of the thing or quality, while un- often denotes the opposite of the thing or quality" [Century Dictionary].
vascular adj.
1670s, in anatomy, "pertaining to conveyance or circulation of fluids," from Modern Latin vascularis "of or pertaining to vessels or tubes," from Latin vasculum "a small vessel," diminutive of vas "vessel."
