Variety speciosa is the tall, robust, broad-leaved race of the species occurring throughout much of the range. Relatively few-leaved plants with more open paniculiform arrays from Illinois, Indiana, Michigan, Minnesota, and Wisconsin have been treated as var. jejunifolia; the status of that variety is uncertain and it may deserve recognition. Some specimens that have been assigned to var. jejunifolia are either typical S. uliginosa or possibly hybrids with that species. Narrower-leaved plants have been treated as var. angustata; the type material comes from eastern states, but the name has been misapplied to plants of var. rigidiuscula (with persistent narrow basal leaves) from the prairies and prairielike habitats along the western edge of the eastern deciduous forest in the United States (M. L. Fernald 1950).
