Containing or resembling flour; having a starchy or mealy composition; farinaceous.
From Latin 'farina' combined with the suffix -ulent (meaning 'full of' or 'abounding in'). This is an older or more technical variant of farinaceous.
This word is practically obsolete, replaced by the more common 'farinaceous,' but it shows how English once had multiple ways to say 'floury'—linguistic redundancy that eventually got pruned away!
