Great plant. The name, Sarc. hartmannii ' Drayton ' could well be it. The 'Drayton' was a variety name used by a very large nursery here in Australia ( not going now tho ). They were in Toowoomba, Queensland... Florafest Nursery. The plant would have had to be imported or as a Selfing of the original plant or a crossing with possibly Sarc fitzgeraldii and brought into the USA in flask form. Its not fully a hartmannii shape.
