I know this is an old topic (almost 12 months) but I thought it would be of interest to know that this Alcantarea has now been named and registered.
It has been called Alcantarea 'Raymond Golden Brown'. The Alcantarea was named and registered by Peter Franklin of Australia. He does comment that the plant has links with A. extensa. You can see photos now on the photo index of FCBS, and a little background to the plant is recorded on the database. Good to see another "unknown" crossed off the list.
