Looks like 'George L. Taber' often spelled Tabor.

I'm afraid I don't know the name of it as its been there too long so that's why I just put it in the general section.

Actually R. formosum isn't the generic entry, it's a specific species with specific descriptive blooms.

I'll move your images as well as two other images in that entry to the generic entry.

Oops! Ok, thank you!
