cratoxylum

Cratoxylum (or Cratoxylon Blume, an orthographic variant) is a genus of flowering plants in the family Hypericaceae, native to tropical Asia. The generic name is from the Greek meaning 'strong wood', referring to the timber.

Cratoxylum species grow as shrubs or small to medium-sized trees. The bark, drying black, produces a yellow resinous sap. The flowers are white or pink to crimson. The ellipsoid fruits consist of three valves.

Cratoxylum species grow naturally from India through southern China ...
