What does corkwood mean?
Corkwood is the common name given to a number of unrelated trees and shrubs whose wood is remarkably light and soft, resembling commercial cork in texture. The name is applied to distinct species on different continents: Leitneria floridana grows in the southeastern United States, various Commiphora species are found in Africa, and Duboisia species occur in Australia. What unites them under this single vernacular label is not botany but timber quality — their wood is so light and porous that it has historically been valued for floats, fishing gear, and other uses where buoyancy or low weight mattered more than strength. Because it is a shared common name rather than a precise scientific term, writers typically specify the region or species when discussing a particular corkwood. The word appears mainly in botanical, ecological, and woodworking contexts, and its usefulness lies in capturing an appealing idea: a tree so airy that its timber can rest weightily in the hand like a piece of dried bark.
nounAny of various trees or shrubs whose wood is exceptionally light and cork-like in texture, including species in Africa, Australia, and southeastern North America.
- Any of several unrelated trees or shrubs with very light, cork-like wood, such as Leitneria floridana of the southeastern United States, various African Commiphora species, and Australian Duboisia species.
"The fisherman's float was carved from corkwood, light enough to bob on the gentlest ripple."
"The botanist noted that the corkwood along the riverbank felt almost weightless when a branch was cut."
"Indigenous Australians used the soft timber of the corkwood tree for making fishing implements."
Used when referring to multiple individual trees or to several of the different species collectively called corkwood.
"The reserve protects stands of both the American and the African corkwoods."
Florida corkwood (Leitneria floridana) has some of the lightest wood of any tree in North America — so buoyant it was once used for fishing floats.

Etymology of corkwood
The compound word corkwood combines "cork" — borrowed into English from Dutch or Low German forms related to the bark used for bottle stoppers, attested in English by the early seventeenth century — with the native Germanic word "wood." As a descriptive vernacular name, it was applied independently by English-speaking settlers to different lightweight-wooded trees they encountered in Africa, Australia, and North America, which explains why the name covers botanically unrelated species sharing no common ancestor or origin.

How corkwood is actually used
A botanical rather than everyday term, "corkwood" is applied to several botanically unrelated species across different continents that share only the trait of unusually light wood. Context usually makes clear which species is meant.
Easily confused with corkwood
Cork is the buoyant bark harvested chiefly from the cork oak, while corkwood refers to whole trees whose timber resembles cork in lightness.
