The Torchwood family (Burseraceae) is a modest sized family of very resinous trees in order Sapindales. Many are famous for resins used medicinally, as incense and for various industrial purposes. particularly Frankincense and Myrrh. The photo is of a Gumbo Limbo tree (Bursera simaruba) native to the Caribbean region, including southern Florida. Its only culinary use is as a windbreak to protect crops from hurricanes. The fruit arils may be edible but are too small to harvest, except by birds. The resin is used as incense, glue and varnish, and is being studied as an anti-inflammatory medicinal.

Pili Nut - [Canarium ovatum]
This nut tree is native to the maritime regions of Southeast Asia, Papua New Guinea and Australia, but are a commercial crop mainly in the Philippines. Currently, the nuts are gathered in the wild, though there are a couple of commercial plantations started - the problem is the trees are very difficult to propagate reliably. A new variety, Poamoho, has been developed in Hawaii which has good production quality, and the seeds don't stick hard in the shells.
Raw, these nuts taste much like pumpkin seeds. Roasted they have a light nut flavor similar to Brazil nuts but are much softer. The dark brown seed coat is too thick to ignore and has to be removed. This is easily done if you split the two halves apart.
Pili nuts are about 8% carbohydrates, 12% protein and 70% fats and
have significant amounts of calcium, phosphorus, and potassium. Pili
nut fats are about 50% monounsaturated and 35% saturated. The The main
markets for these nuts are Hong Kong and Taiwan where they are an
ingredient in one type of moon cake, but they are shipped all over
Southeast Asia and the Pacific islands. The photo specimens were
lightly roasted and were typically 1-1/2 inches long and weighed 13
to the ounce.
Chinese Black Olive -
[Wu lan; Canarium pimela syn. C. tramdenum]
This fruit is preserved in brine and used similarly to black ripe
Oleaceae olives but is not really an olive at all. It is the fruit of
a large resinous tree, related to the frankincense tree, native to
Southeast Asia and southern China. The flesh is
relatively thin and the seed large and sharply pointed at both ends. Aside
from the brined fruit, the seed kernels inside the pits of this and
related species are sold as Canarium nut, Pili nut or Galip nut. The
photo specimens were purchased from a large Asian market in Los Angeles,
packed in brine.
Chinese White Olive -
[Nam liap, Samo chin, Kana (Thai); kan-lan (China); buah cana (Malay);
This olive shaped fruit is used similarly to Oleaceae olives but is
not really an olive at all. It is the fruit of a large resinous tree,
related to the frankincense tree, native to Southeast Asia and southern
China. Why it is called "white" is unknown to me. The fruits are used in
cooking both fresh, where they are somewhat resinous, and preserved by
soaking in brine and drying. They are particularly popular in Thailand and
Vietnam. This fruit is also used in Asian herbal medicines and cosmetics.
