A Grammatical Dictionary of Botanical Latin

calix,-icis (s.m.III), abl. sg. calice: a cup, goblet, a drinking-vessel. Latin ‘calix’ derives from Gk. kylix,-ikos (s.f.II), a cup, drinking-cup, wine-cup; see calyx; see cup, cyathus;

- ‘kylix’ poculi genus, quod nos una littera immutata calicem dicimus, is a kind of drinking vessel, which we call a ‘calix’ [i.e. calicem, acc. sg.] with one letter unaltered.

Poculum,-i (s.n.II), abl. sg. poculo: a wineglass; a drinking-vessel, a cup, goblet, bowl, beaker; syn. calix, cyathus {Lewis & Short).

NOTE: the prefix calic- is often confused with calyc-, but the first refers to a cup [i.e. a drinking vessel], the second to a flower organ. Jackson makes the following corrections of adjectives intended to refer to the calyx, but formed from ‘calix:’

calicalis = calycalis; calicatus = calycatus; calicinaris, calicinarius = calycinaris, calycinarius; calicinianus = calycinianus; calicularis = calycularis; caliculate = calyculate.
