Original diagnosis/description

Scape slender, slightly over 1 millimeter in width; apparently angled, but this feature is somewhat problematic. Inflorescence distinctly pedunculate, about
1.4 centinleters in length and 3 millimeters in maximum diameter, bluntly rounded distad and somewhat tapering proximad. The specimen is unfortunately broken away about 2 millimeters above the attachment of the spadix, so that it can not be determined whether the spathe was a narrow contitiumtion of the scape and not obviously differentiated, as in the existing species of Acorus, or whether it expanded, as in most modern Araceae. Scape preserved for a distance of 2.2 centimeters.
