When I was young, I took a few years of Shaolin-Kempo-Karate at a couple Villari's dojos. As part of our training, we had the expected set of katas that we were required to learn. However, there was another class of forms that we were required to learn that resembled the Kata in classification but clearly were different in technique and style. These were referred to as "pinyons". While our katas (at least the ones that I learned while studying) typically had us move in an "H" pattern, and essentially contained a shorter set of techniques repeated 3 times. The pinyons, I do not remember quite as well, but I do recall them having us stepping in more directions and containing more variations in stances (such as cat stance, as well as horse stance and half-moon stance). They also featured a greater variation in striking, and contained less repetition (if I'm remembering properly).
I've never heard the term "pinyon" used anywhere else so I'm not really certain from where these forms came from, if they were created by Villari, or even from what language "pinyon" derives.
Does anyone have any insight into this?
