Hello Martin and Berndt, Here's an old article(thanks to Google)which implies that the original article naming these lamellae, by Brezina in 1882, referred to thin troilite plates oriented parallel to the cube planes of iron. They were first described by Reichenbach in 1861. This article also implies that the term has been subsequently used very loosely so that the original definition has been blurred somewhat:
