Type collection: Kalbreyer 1413, "tufted habit, 2 1/2-3'; leaf erect, thin; spathe 5-6" 1., green, nerved when old inside white; spadix bent greenish or yellowish; forest shady marshy spaces 3000'; Rastrojas," Colombia, 15 Feb 1880 (holotype K).
S. kalbreyeri is limited to the Magdalena Valley of Colombia and adjacent Darien, Panama. It is remarkably similar to S. cuspidatum., but is probably distinct. Each of these species has a very limited range, and is separated from the other by all Guayana and the Cordillera Oriental of the Andes. S. kalbreyeri is distinct in its oblong spathe which is proportionally somewhat narrower than in S. cuspidatum.. There is a tendency toward a small reduction in the number of ovules per ovary in this species, and the blade of the leaf and the spathe are coarser in texture than in S. cuspidatum.
