The photographed tree is south of the Chemical Enginering Building. From the Rafael Mangual Coliseum to the natatorium there are two rows of kamani intermixed with calaba trees, from the natatorium to buildings A-D all the trees are kamani. The ten trees bordering the plaza across from the Chardón Building were planted in 1956 by Hipólito Irizarry. There are sixteen additional trees from the Finances Office to the Research and Development Center.
