This is a beautiful plant wild collected in Brazil but as yet not positively identified. A couple of taxonomists have seen it but do not agree as to whether it is a new species, a form of O. rubiginosum or a possible natural hybrid.
For sure it is beautiful so both suggest that the plant be given a cultivar name for the interim. It's a large grower with arching, strap-like leaves that tint red with good light and are dusted with a heavy coating of silver trichomes mainly concentrated on the leaf margins.
The margins appear silver and the center of the leaf appears pink. Marginal spines are white and rather serrate. The inflorescence is a tall scape with long, leaf-like bracts and a couple of clusters of short, light green to yellowish branches with large floral bracts and white flowers. A very handsome species.
