You are absolutely correct, Hugo. I have mixed up a label here, and wrote the name down wrongly. My records show that this was actually down originally as bravoe v San Giro K4466 from Koehres seed. It was amended to albata San Ciro following a discussion with a fellow Mamm enthusiast who also had this plant from the same seed, because as it grew it clearly wasn't a bravoe, not with those spines. An dthen further amended to geminispina ssp leucocentra.
It just goes to show how important it is to keep the original seed or plant details!!
