Natural History & Notes

Fruit eaten by several species of birds. Cooper & Cooper (1994).

The species epithet commemorates Clifford Halliday Gittins. Although Nooteboom indicated (Brunonia 4(2): 321 (1981)) that his original misspelling of the varietal epithet as "gittonsii" had to be retained, it is treated as an error to be corrected under ICBN Art. 60.1 (Vienna Code (2006).
