Materials examined. Table 2 . Medium-sized tree about 9 m high. Leaves elliptic to lanceolate, 15–20 × 5–6 cm , coriaceous, glabrous but with sparse hairs on the midrib. Inflorescences termi- nal, pubescent, many-flowered. Calyx 6 mm , rhomboid, pubescent. Corolla white, urceolate, pubescent outside, lobes 3 mm , tube 4 mm . Fruits ellipsoid, 7–10 mm , brown, pubescent. This species has the largest flowers compared to all Greeniopsis species and is easily recognized by its somewhat glabrous leaves and stipules ( Alejandro et al. 2010 ). Greeniopsis multiflora (Elmer) Merr., PJS 4 c (1909) Bot. 325. Materials examined. Table 2 . Fig. 4C Shrub about 2 m high, pubescent. Leaves elliptic to obovate, 20–25 × 10–15 cm , glabrous with scattered hairs on midrib. Inflorescences terminal, sparsely pubes- cent, many-flowered. Calyx 2 mm , rhomboid, pubescent. Corolla white, urceolate, pubescent outside, lobes 1 mm , tube 1–2 mm . Fruits subglobose, 4–5 mm , brown, pubescent, with calyx remnants. In contrast to the other Greeniopsis species found in Eastern Samar and assessed as Critically Endangered, G. multiflora is very widespread across the Philippines .
