Hamet considers it allied to 5. Aliciae Hamet, indicum Hamet [paniculatum Wallich), perpusillum Hooker fil., Przewalskii Maximowicz, and Schoenlandi Hamet, and gives the points of difference. Species Incompletely Known. 151. ? Sedum polyrhizum Praeger, sp. nov. (fig. 185). At once separated from all other species in cultivation by its curious stems, densely armed with rough scales arranged in rings, and shaggy with short aerial roots almost to the tips. 5. oaxacanum Rose, which resembles it in habit more than do most of the Mexican species, has its stems somewhat similarly roughened, but to a very much less extent, and oaxacanum is a much stouter plant with broader leaves and no aerial roots. The present species much resembles in habit and leaf a small S. album. The plant came from New York Botanic Garden labelled S. oaxacanum, and is probably Mexican. Though it grows freely, all efforts to get it to flower have been unsuccessful both at Glasnevin and in my own garden, so that its reference to the genus Sedum must.
