Here's another easy one, and in keeping with the tropical/Hawaii theme of my plants (people get lost on island vacations too

)....
Location:
The plant/tree was believed to have originated in the Southeast Asian Islands and spread via human migration through Melanesian and into Polynesia. It is especially prominent and cultivated in pacific island cultures, and I'm sure it's been spread to other tropical areas. If I remember correctly, this tree is also able to grow on coral sand.
Description:
The tree grows up to 15-20m high. It's bark is light colored and the wood is a golden color. The leaves are broadly obovate to broadly ovate, and are often pinnately lobed. The leaves are a dark green and slightly glossy on the top, and dull green on the bottom. The midrib and veins are often covered with red/pink hair. The seedless fruit is round or oblong, up to 20cm wide by 12 cm long, with a green or yellow-green skin that is distinctive for its bumpy and sometimes spiny appearance. The flesh is white or a light yellow. The tree fruits all the time, but I think its most productive in summer through winter.
Uses:
The fruit is very nutritious and is a staple in the tropics. It can be eaten at all stages of maturity, but it is most commonly eaten when mature (yellow-green and bumpy skin). The fleshy white interior is the edible part. Though mostly composed of water, the fruit is very starchy. When cooked the taste is often compared to that of other starch staples. It is prepared in a variety of ways. You can bake or roast it. You can boil it. Traditionally, it was often left to ferment in a pit (useful for long term storage). One popular method of preparation is to mix the cooked fruit with coconut milk and bake it.
The tree was also useful aside from its fruit. The bark was used medicinally, the timber was used in canoes and surfboards or as firewood, the bast was used to make cordage or bark clothing, and the leaves were used medicinally or to wrap food. Some of the more novel uses arise from the natural latex obtained when any part of the tree is broken (collect the sap); it would serve as medicine, an adhesive, caulking for canoes and containers, birdlime (to catch birds for food or for their feathers), and even chewing gum.
Whoa! Knife usage!
