Description and Ethnobotany

Growth Form Utania nervosa is a tree that usually grows to 1 -5 m tall. 
Trunk Bark is grey brown to dark brown and mostly smooth (sometimes slightly fissured).
Foliage Leaves are smooth, elliptical (20 -31 cm long and 11 – 15 cm wide) with petiole (5 – 12 mm long). Leaf has 10 -16 pairs of secondary veins. Veins are sunken on the upper surface of leaf blade and protruding on the underside of leaf blade. 
Flowers Inflorescence (0.8 – 2 cm long) is densely crowded with cream yellow to white flowers, and hangs pendulous at the terminal end. Branching tiers are very often closely spaced. 
Fruits Fruits are smooth (about 1.4 to 1.8 cm long) and compactly clustered together as a result of closely spaced fruiting tiers. Fruit apex is beaked and base clasped by calyx lobes. Seeds slightly elongated (0.15 cm to 0.2 cm long). 
Similar Utania nervosa and U. racemosa are very similar. You can tell them apart by looking at the secondary veins. U. nervosa has 10–16 pairs while U. racemosa has 5–7 pairs. U. nervosa also has a thicker flower stalk (5 – 6 mm diameter), as compared to U. racemosa (2 – 4 mm diameter).  
Associated Flora Utania nervosa was previously misidentified as Fagraea racemosa by Leenhouts (1962).
