Filler
From Cigar Wiki
q.v. Anatomy of a Habano
The filler (Bonche) is the inside of the cigar and source of the cigar's flavor. It usually consists of three different sorts of tobacco leaves:
Volado: Light-flavoured leaf, especially valued for its combustibility – also known as Fortaleza 1 (Strength 1).
Seco: Medium-flavoured, the most important leaf for aroma - Fortaleza 2 (Strength 2).
Ligero: Full-flavoured, slow-burning for a touch of strength – Fortaleza 3 (Strength 3).

Wrapping the filler with the binder, you get the so called Bonche.
