A rare species from Rio Grande do Sul in Southern Brazil where it grows as an epiphyte and lithophyte. A very handsome species with short, flattened, segmented stems that later become three or four angled with age. New growth tends to be reddish. Upright at first then becoming pendant with maturity. There is some question about this species taxonomic place and future nomenclature changes may be made, but for now at least, this is the accepted name for this taxa. A choice, decorative and hard to find plant.
