Ehretia dunniana H. Lév.

Ehretia dunniana is very similar to E. longiflora Champion ex Bentham, and differs by having conspicuous reticulate veins and densely rust-colored glandular inflorescences, calyces, and young branches. Léveillé (Repert. Spec. Nov. Regni Veg. 11: 65. 1912), described the cymes as "villous," but Johnston (J. Arnold Arbor. 32: 104. 1951) indicated that they are densely covered with reddish brown, short, stipitate glands, as described here. Glands are also found in the type of E. volubilis Handel-Mazzetti.

Trees 10-15 m tall; branchlets dark brown, glabrous; young branches with thin glandular hairs. Petiole 2-3 cm, glabrous; leaf blade elliptic to oblong, 10-18 × 5-10 cm, glabrous, base broadly cuneate to rounded, apex abruptly acute; lateral veins 6-8 pairs, reticulate veins obvious. Cymes terminating lateral branches, flat topped, 6-7 cm wide, densely pubescent, glandular. Calyx 3-3.5 mm, densely thin glandular pubescent; lobes oblong, 1.2-2 mm, ciliolate. Corolla white, tubular-campanulate, 1-1.1 cm, fragrant, base 1-1.5 mm wide, gradually expanded upward; throat 4-4.5 mm wide; lobes oblong, 4-5 mm, obviously shorter than tube. Filaments 2.5-3 mm, inserted at upper part of base, 5.5-6 mm; anthers 1.5-2 mm. Style 8-8.5 mm, glabrous, branches 0.5-1 mm. Drupes red to dark red at maturity, ca. 1 cm in diam.; endocarp divided at maturity into 4 1-seeded pyrenes. Fl. Mar, fr. Apr.
