Praravinia stenophylla (Merr.) Bremek., J. Arnold Arb.

21 (1940) 44.

Materials examined. Table 2.

Tree about 2 to 3 m high. Leaves narrowly elliptic to linear-lanceolate, 12–13 × 1.2–1.5 cm, glabrous but with scattered trichomes. Inflorescences solitary, axillary. Calyx somewhat globose, 3 mm in diameter. Corolla valvate, white, lobes 3–5 mm, tube 1 mm. Fruits not seen. This species closely resembles P. glabra (Merr.) Bremek , another endemic species, but is easily distinguished by its very narrow leaves.

This species was previously recorded only on Luzon at the type locality, but our observation extends its geo- graphic distribution to Samar.
