However, the new species differs from the latter by its leaves with long petioles (1.4–1.9 mm long), staminate inflorescences in cincinni, staminate and pistillate flowers with long pedicels (3.8–4 mm long and 6.7–8 mm long, respectively), staminate disk and smooth seeds. Its distribution, habitat, phenology, and informal conservation status are presented.
