Abstract

We describe a distinctive new species of Eriobotrya condaoensis (Rosaceae) from Con Dao National Park, Ba Ria-Vung Tau Province, southern Vietnam, based on both morphological and molecular evidences. The new species is characterized by leaf blade oblong-oblanceolate, 8–12 × 4–6 cm, leaf margins crenate, both surface glabrous, secondary veins 6–7 pairs, bracts apically dentate and persistent, flowers sessile and yellowish, hypanthium funnel-shaped and brown tomentose, petals elliptic and 6–7 × 4–5 mm long, styles 2, free at base and 5–6 mm long, and ovary glabrous. Morphological characters and phylogenetic analysis based on nrDNA ITS sequences confirmed the distinctiveness of this new species in the genus.
