According to the Catalogue of Life, all three of these names (Bukiniczia cabulica, Aeoniopsis cabulica, and Dictyolimon macrorrhabdos) are accepted names and are not synonymous. This means either that the research has not reached the point of reclassification or that they are three separate plants. This could explain the differences in their descriptions. The Russian site mentioned in one of the threads pertaining to the plant, for example, says the plant is described by various sources as perennial, biennial, and monocarpic.
