The most exceptional of the Mānoa Campus trees are protected by The Hawaiʻi State Legislature Act 105, which designates an Exceptional Tree as “a tree or stand or grove of trees with historic or cultural value, by which reason of its age, rarity, location, size, aesthetic quality, or endemic status has been designated by the county committee as worthy of preservation.” Through this act, The Hawaiʻi State Legislature recognizes that “beyond their aesthetic worth and cultural significance, trees perform an important role in maintaining ecological balance, in increasing soil conservation and natural oxygen production, as windbreaks for necessary plant species, and in retarding flooding, erosion, siltation, lateral distribution of air pollution, and noise” (State of Hawai‘i Department of Natural Resources n.d.: n.p.).

Couroupita guianensis Aubl. - cannonball tree
South America, Protected - Exceptional Tree Status, Planted in 1933 by the playwright Thornton Wilder on the makai side of Sinclair Library, the Cannonball tree is nearing extinction in the wild. Native to northeastern South America, the tree is named for the dozens of round, rust-colored grapefruit-like ‘cannonballs’ clustered around the trunk, which crash down to the ground when ripe, releasing a pungent unpleasant odor. When first in bloom, highly fragrant salmon-colored flowers emerge in clusters around the trunk of the tree. These bloom for only one day before transforming into the ‘cannonballs,’ which takes about 18 months to mature (Belknap 1982: 40).
