Two years ago, from Plant Delights Nursery, I bought a cultivar they called Ruscus hypoglossum 'Mr Lonely'. There is a cultivar with that name in the database here under Ruscus aculeatus. I think these are two different species, but since I can't find any other source I am not sure what is correct for Mr Lonely.
It was added to the database by jmorth- hey @jmorth where did you find it listed like that?

Could have been Plant Delights Nursery. I usually visit there at least once a year to see what's new.

R. hypophyllum is sometimes incorrectly labeled as R. aculeatus (Butcher'sbroom)

I will try to figure this with more resources tomorrow,
