Discussion
Species 1.
Polypremum is sometimes confused with Loeflingia and Scleranthus of the Caryophyllaceae; the opposite, linear-acuminate leaves and axillary flowers are suggestive of those taxa. The relatively small, but conspicuous, white petals (absent or at most rudimentary in Loeflingia and Scleranthus) and the two-lobed capsule (three-valved capsule in Loeflingia, utricle in Scleranthus) distinguish Polypremum.
