I don't know where you got this idea.

I refer to canes such as these as having "submerged stripes." These are layers with stripe units, that are covered-over by an additional layer of (usually transparent) glass. All of this is in contrast to conventional canes that have superficial stripes that are on the surface of the cane; or star canes that have stripe units inserted between the points of the starry layer (then often covered by a transparent layer).

Canes of the class you are showing often have one or two layers of stripes, and the stripes are usually single round canes that are spaced apart. (In fact, they may be two-layered canes that are white overlaid with a transparent exterior, so that they automatically separate from each other, when placed—so that a transparent separating-cane doesn't have to be used between white canes.) These canes can also be unmolded (like yours), or they might be flower or star canes.

The submerging of the stripes makes the beads visually similar to old-time "gooseberry" beads—that may be the earliest conventional Venetian beads made with submerged stripes.

Anyway, I call these "submerged stripes."
