Thanks Mark, I didn't know that Lau didn't name this initially. I have another L1116 which is very much like the supertexta that we know, and which Hugo posted earlier.
I find in my records that I bought this possible cuckoo at a Garden Centre in 1993, so there can't be too many generations from Lau's original collection. As you say, it could be of hybrid origin, but also it could have been wrongly labelled. If it is the first, then that's OK, I can just label it as such. If it were a hybrid, I guess it would have to be something fairly close, still in the Supertextae.
But if it were the second - quite a likely possibility knowing how Garden Centres work - what might it be? My thought has always been that it looks closer to crucigera ssp tlalocii or grandinosa than supertexta, although the brownish bristles on the areoles actually suggests the type to a greater extent.
Anyone with anything similar in their collections??
