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).
