Abstract
Here we describe a new species, Vaccinium pseudopubicalyx, and report a new record for the flora of China, V. viscifolium, both from Hainan Province. Vaccinium viscifolium also represents the first record of V. sect. Euepigynium for China. Detailed descriptions and illustrations with analytical photographs of the two taxa are provided.
Keywords: Morphology, new species, taxonomy, Vaccinium pubicalyx

Vaccinium pseudopubicalyx X. H. Ye, Q. L. Wang & Y. H. Tong, sp. nov.
Diagnosis: Vaccinium pseudopubicalyx is morphologically similar to V. pubicalyx and its varieties, but can be distinguished by having fewer pairs of secondary veins (3–5 (Fig. 2E) vs. 5–9 (Fig. 5A, B)), smaller (2–3.5 × ca. 1 mm vs. 5–8 × ca. 1.5–2 mm) and lanceolate (vs. ovate) floral bracts, young twigs and inflorescences rachis white-pubescent (vs. brownish-tomentose), and anthers with smaller dorsal spurs (0.5–1 mm vs. ca 4 mm, Fig. 5F).
Etymology: The specific epithet pseudopubicalyx, a noun in apposition, alludes to close alliance to Vaccinium pubicalyx.
Vernacular name: 拟毛萼越橘 (Chinese pinyin: nǐ máo è yuè jú).
