/ˈfɛləm/

Origin: A borrowing from German. Etymon: German Phellem.

Etymology: < German Phellem (F. von Höhnel 1877, in Sitzungsber. der Kaiserlichen Akad. der Wissensch. Wien: Math.-Nat. Classe 76 600) < ancient Greek ϕελλός cork (see phelloplastic n.) + German -em-em suffix.

Botany.

The outermost, protective layer of the periderm of plant shoots and roots, typically composed of tightly packed, suberized cells; cork tissue (cf. cork n.¹ 5).
