Is the Ironwood mentioned the same as Australian Ironwood, which is a subspecies evergreen pine? If so, what part of the tree is used?
The Australian Ironwood was used to over-plant Midway Island in the Mid-Pacific, part of the Hawaiian chain but as far from Honolulu as
Omaha is from New York City. I think it was the trans-Pacific cable company that planted them when they stationed people on the island,
to give it some landscape. It passed from them to the airlines, and then to the Navy for many years from before World War Two until
the 1990's, and now it "belongs" to the Department of Interior. But perhaps this is a different Ironwood.
