Japanese name: ムニンビャクダン（無人白檀） Scientific name:Santalum boninense
[Overview]
An evergreen shrub 1–3 m tall, growing in sunny, somewhat dry woodland.
It is a semi-parasite whose hosts include Shima-isunoki, Sharinbai and Teriha-hamabo, and because it has chlorophyll it also photosynthesizes.
It branches well and forms a clump.
The branches are often upright.
Leaves are simple and opposite, elliptic, 3–7 cm long, somewhat thick, and entire.
On young leaves the underside is tinged powdery white.
When the leaves dry, the veins become raised on the upper surface.
The petiole is 3 mm.
Many flowers are borne in cymes 4–5 cm long that emerge from the leaf axils at the branch tips.
The corolla is a narrow bell 5 mm long, 4-lobed, pale green and fragrant.
The fruit is a drupe, ovoid-elliptic, 15 mm long, ripening reddish purple, with part of the perianth remaining at the top.
It only rarely sets fruit.
The heartwood is yellowish red-brown with a faint scent similar to Byakudan.
