The only place I've ever seen this name in use is as part of the name of an Austrian archduke:
Rudolf Syringus
Peter Karl Franz Joseph Robert Otto Antonius Maria Pius Benedikt Ignatius Laurentius Justiniani
Marcus d'Aviano.
It is also found as part of the Latin name of some plants.
Does anyone have more information on it? Other forms or history.
I'm not looking for comments about how awful it is and how it looks like the word syringe. Not planning to use it just trying to learn more about it.
