† ochopetalousadj.
Origin: A borrowing from Greek, combined with an English element. Etymons: Greek ὀχός  , -petalous comb. form.
Etymology:  <  Hellenistic or Byzantine Greek ὀχός (see note) + -petalous comb. form.R. G. Mayne (see quot. 1857) glosses Greek ὀχός as ‘capacious’; however,  Liddell & Scott's Greek-Eng. Lexicon (ed. 9, 1940) defines this word as ‘firm, secure’, with a single example (Philo Byzantius), and derives it from ἔχειν to have, hold. R. G. Mayne gives a Latin form ochopetalus and a French form ochopétale.  N.E.D. (1902) gives the pronunciation as (ǫkope·tăləs) /ɒkəʊˈpɛtələs/.
