This species is difficult to differentiate from Geranium delavayi when fresh petals are not available to observe their colors. However, G. pogonanthum has staminal filaments with longer and abundant trichomes and longer petals. Glandular indumentum is also variable in G. pogonanthum, being sometimes just present on the stem base and other times only on the inflorescence. Bracteoles are sometimes filiform, like in G. delavayi, and other times lanceolate as in G. yunnanense.
