Here is an update on heuffelii 'Hispedulum'.
I have watched this one for a couple of years now.
Belcore is a love, velvety heuffelii.
I don't believe my 'Hispedulum' is Belcore 3, as Belcore 3 has a very nice velvet texture according to all the photos I find. My 'Hispedulum' does not show that trait.
