I think this plant is Haworthiopsis attenuata, which is way more common in cultivation and can be distinguished by the upper surface of the leaves having bumps or ridges on top, and not being smooth like H. fasciata. These plants are frequently confused but attenuata is way more common, and that feature is a sure fire way to tell them apart. I would like to propose moving this image to H. attenuata.
I am also seeing bumps on the upper leaf surfaces of this plant.
What do you think?
Does this flower correspond to one or the other plants above?
