Yes, it would be the same plant as the plant in that entry. I'm not sure about the davidii in that name. B. x weyeriana was published and described in 1920 as a hybrid species: B. davidii x B. globosa. The status of the name was subsequently disputed, and it looks as though it has been ruled out as an accepted species name. If 'Bicolor' is a hybrid of two species, the species name doesn't belong in the title of the entry.
