Taxonomic Comments
Nemacladus bellus is described as a new species by Morin and Ayers (2020). "The Greenhorn Mountain populations are recognized here as a distinct species. In addition to characters mentioned by Robbins (1958), they differ from N. secundiflorus var. secundiflorus and var. robbinsii in having basal leaves broadly elliptic to ovate-deltate, 1.2-4 mm long, with margins shallowly toothed or wavy. Nemacladus secundiflorus basal leaves are oblanceolate to spatulate, 1.5–12 mm long, the margins irregularly lobed" (Morin and Ayers 2020).
