The new species is similar to Viridantha lepidosepala but differs in the size of the leaf blades (4–5 × 0.3–0.4 vs. 7–12 × 0.5–0.8 cm), in the characteristics of the peduncle (conspicuous vs. inconspicuous, 1–1.5 vs. 3–4 mm diameter), in the length of the peduncle bracts (shorter than the inflorescence vs. longer than the inflorescence), and in the length of the petals (2.5–2.8 vs. 1.5–2.5 cm).
Etymology:—The specific epithet refers to the small size of the plants of the new species.
