Thanks Craig, and you are correct. I should have 'splained it better.
I've never found the word 'scroll' or 'leaves' in the mid to late 1800s Belgian and British descriptions of methodology or pattern nomenclature.
Alternees is obviously French. Steve Culver already told me neither a c. late 1800s nor modern blacksmith would approve
Dr Gaddy used the scroll or whorl words, and I do think they are appropriate descriptive terms
That said, the 'scroll' that we see in the pattern is made up of the 2 halves of adjacent rods hammer welded. The rod would have at least twice the numbers I stated for the 1/2 scroll.
You can count the alternees pretty easily in this image, and can see how the 'outside' alternee joins the adjacent scroll. I count 12 and possibly 13 iron alternee, for a total of 24 or 26. The rod is between the two 'zipper' (wavy) welds.
