Viet Nam: cây duong
Small tree or shrub with milky sap (20 m or higher) and a trunk diameter of 0.6 m; round or spreading crown, branches smooth and mottled grey, marked with orange-tan stipular scars, shallow rooted; sheds most of its
leaves at the end of the growing season.
Bark: Tan or light grey with pale orange to light tan stripes, becoming yellowish with age, smooth to slightly fissured.
Leaves: Greyish, rough surface above and fuzzy-downy below, simple, shape variable – either egg-shaped with a broad and round base tapering towards the end, heart-shaped or deeply lobed (7–20 cm long), margins with forward-pointing fine projections or teeth; held alternately or almost opposite each other on stems; leaf stalks are 3–10 cm long.
Flowers: Male flowers yellowish-white in clusters (3.5–7.5 cm); female flowers in rounded clusters, round heads (about 1.3 cm wide), hairy.
Fruits: Syncarp (a fleshy compound fruit), berry-like, initially green turning red, purple to orange as it matures, fleshy, round (1–2 cm wide) with many embedded or protruding tiny red seeds.
China, India, Japan, Korea, Malaysia, Pakistan and Thailand.
Fuelwood, fodder, paper, pulp, shade and ornament.
Roadsides, disturbed areas, wastelands, urban open space, plantations, forest edges/gaps and riparian vegetation.
Forms dense stands that displace native species, prevent forest regeneration and reduce water availability. In Pakistan, B. papyrifera limits the growth of Dalbergia sissoo Roxb. (Fabaceae), Morus alba L. (Moraceae) and Ziziphus sp. In the Philippines, native species such as Trema orientalis (L.) Blume (Cannabaceae), Macaranga tanarius (L.) Müll. Arg. (Euphorbiaceae), Melanolepis multiglandulosus (Reinw. ex Blume) Rchb.f. & Zoll. (Euphorbiaceae), Mallotus philippinensis (Lam.) Muell. Arg. (Euphorbiaceae), Ficus nota (Blanco) Merr. (Moraceae), Ficus septica Burm., Ficus ulmifolia Lam., Polyscias nodosa (Blume) Seem (Araliaceae), and other species were displaced by paper mulberry (Baguinon et al., 2003). Paper mulberry produces considerable amounts of allergenic pollen which has been shown to exacerbate asthma in sufferers. In Islamabad, Pakistan, paper mulberry can account for 75% of the total pollen count contributing to ill health and even death in the old and infirm.
