More wrenches!
Gilda, now that I see your photo of the two plants together (thank you!), I take back that I think your Albopurpureum is properly labelled.
You see, Albopurpureum is Dominianum x schlimii. Phrag schlimii it a small growing species and Dominiamum is caudatum x caricinum. Phrag caudatum is not so big and "leafy" as your Albopurpureum.....and caricinum is a small, almost grass-like looking species. Phrag Albopurpureum isn't a large plant. It simply doesn't have the genetics for it. I'll bet that 'Sir Arthur' is an old, old awarded plant that was mislabelled either by accident or as often happened, on purpose because it looked like an Albopurpureum on steroids, even though, it wasn't Albopurpureum. Think about that famous awarded plant schlimii 'Wilcox'. It's a Cardinale (Sedenii x schlimii); but, someone pulled a fast one and called it schlimii. It looks like a giant schlimii. Unfortunately, the judges were asleep at the wheel, or they were in on the name change.....
Look at the foliage of your plants. It's lo-ooong.....like longifolium! Schroderae is Sedenii x caudatum. Phrag. caudatum is large; but, has fairly upright to arching leaves. Sedenii has long, arching, soft, strap leaves as a result of having longifolium as a parent.
So, lets say that the one on the right is actually a Schroderae. Schroderae should be much larger than Albopurpureum with longer foliage; but, the opposite is the case with your plants. The one on the left, just by looking at it's foliage is just too big and has leaves that are too long for it to be a true Albopurpureum. It's more likely a Schroderae as well....a nice, robust one; or, it was made with Dominiamum x (schlimii) 'Wilcox', which would introduce longifolium into it's gene make-up. Or, the Dominianum parent might have been mislabelled and was actually a Grande (caudatum x longifolium). Again, more longifolium. Whatever the case is, 'Sir Arthur' seems to me to have some big, honkin' longifolium in it's family tree somewhere, because Albopurpureum isn't supposed to have anything but fairly stiff and compact growing (caudatum), genes and some miniature, almost grass-like (caricinum and schlimii), genes in it's make-up. In fact, Albopurpureum's genepool is 75% from miniature, almost grass-like growing plants. Such a monster as 'Sir Arthur' is impossible to get from that breeding.
