Origin: A borrowing from Latin, combined with an English element. Etymons: Latin -florus  , -ous suffix.
Etymology:  <  post-classical Latin and scientific Latin -florus (in e.g. multiflorus   (see multiflorous adj.), milleflorus   (see milleflorous adj.);  <  classical Latin flōr-  , flōs  flower n.) + -ous suffix. Compare French -flore   (in e.g. uniflore   (see uniflorous adj.), pauciflore  : see pauciflorous adj. at pauci- comb. form ).Attested from at least the early 18th cent. in formations after French and Latin models (e.g. nodiflorous adj. at nodi- comb. form , multiflorous adj.). A large number of formations are first recorded in  R. G. Mayne Expos. Lexicon Med. Sci. (1860) (e.g. pauciflorous adj. at pauci- comb. form ).
