Ptaeroxylon obliquum is a species from the family Rutaceae which are most abundant in South Africa and Australia.

[1] The term ptaeroxylon is Greek for sneeze and wood,[2] while obliquum denotes the oblique shape of the leaflets.

The wood produces oils containing nieshoutol, which causes violent sneeze attacks by workers who are exposed to the tree.

[3] Ptaeroxylon obliquum is a shrub or medium deciduous tree that stands up to 15 metres (49 ft) tall.

[2] Sneezewood is a very attractive wood with golden heartwood with light orange figures and is a favorite amongst woodturners.
