AB -The newly discovered Paraphlomis youyangensis, native to southeastern Chongqing, China, is introduced to the scientific community. This species exhibits similarities in floral structure to P. kuankuoshuiensis but is distinguishable by several discrete features, such as less pronounced rhizomes (<0.5 vs. 2–4 cm), elongated stolons (present vs. absent), smaller leaf blades (1.8‒5.5 × 1.2–3.1 vs. 10–37 × 3–8 cm), leaf margins (shallowly repand and mucronulate vs. serrulate), and shorter bracteoles (1.2–4 vs. ca. 5 mm). Phylogenetic assessments based on two nuclear genes and three chloroplast genes indicated that P. youyangensis has a closer evolutionary relationship with P. yingdeensis but is differentiated from the latter by long stolons, smaller leaf blades (vs. 6.2–16.5 × 4–11.5 cm), leaf margins (vs. crenate-serrate), and notably shorter bracteoles (vs. 7–8 mm).
