At first, I didn't know what to call this week's stitch but finally settled on Danish Knot Chain Stitch.
I found the stitch in Totsuka Embroidery Stitch Book 6,
where its Japanese description translated into English would be: 'like a Cable Stitch followed by Lazy Daisy Stitch repeatedly'.
The excellent Totsuka hand embroidery books are packed with basic stitches and masses of variations. Unfortunately, the stitches have only rarely been given a proper name. Instead, they are often described, as you saw in the example above.
When there is a name, it seldom corresponds with one known in most Western countries. I don't know where Madam Totsuka gets her vocabulary from, but what she calls Cable Stitch is nothing like what we in English call Cable Stitch, nor is it the Cable Chain Stitch. It is known to us as Danish Knot Stitch. Her German Knot Stitch is the same as Sorbello Stitch.
The difference between Danish Knot (Sunday Stitch School #4) and Sorbello Stitch (TAST #152) is that the former is shaped like a triangle and the latter a square. Complicated? Oh, yes!
I made a sampler to compare the stitches and their names:
Names found in most Western stitch dictionaries
The names used in Totsuka's books

Anyway here is today's stitch:
Homework: Add the Danish Knot Chain to these samplers.
