    • Plant Morphology :
      Growth Form: It is a tree up to 7 m tall.
      Foliage: Its opposite, stalked leaves have leaf blades that are lance-shaped, narrowed to both ends, hairless above but densely silvery hairy below, and 8.8 by 4.4 cm, with 7 pairs of veins.
      Flowers: Plants are unisexual with individuals bearing only male or female flowers. Male flowers develop in stalked, axillary, many-flowered clusters. Female flowers develop in stalked axillary clusters of 3–5 flowers each. Its corolla (petal) is yellow and 0.74 cm long. Its calyx (sepal) is slightly round. In the flower of both sexes, the green, 4-lobed calyx is short-hairy and the yellow corolla has 4 lobes each.
      Fruits: Its fruit is ellipsoid, 4-lobed, finely hairy, and about 9 mm long. Each fruit has pyrenes (seed covered by the hard inner fruit wall) that are slightly curved and linear-oblong.
