imbricate
adj.

Having regularly arranged, overlapping edges, as roof tiles or fish scales.


v. im·bri·cat·ed, im·bri·cat·ing, im·bri·cates
v. tr.

To overlap in a regular pattern.


v. intr.

To be arranged with regular overlapping edges.

Surely this is a noun rather than an adjective.

I should think Imbricate would serve as the verb and adjective forms.

From the Etherington & Roberts Dictionary:

A form of embellishment of a book featuring a pattern consisting of overlapping leaves or scales. The term is also applied to any decorative pattern composed of overlapping elements.
