Thespesia grandiflora

Thespesia grandiflora, most commonly known as Maga, and also referred to as Maga Colorada ("Red Maga") and Puerto Rican hibiscus, is a tree in the family Malvaceae of the rosids clade endemic to Puerto Rico, where its flower is officially recognized as the national flower of the archipelago. Although originally native to the humid mountains of limestone in the western and north-central portions of Puerto Rico, today it grows everywhere in the archipelago due to its extensive cultivation. It is also grown as an ornamental tree in Florida, Hawaii, Honduras and various Caribbean islands. The maga is mostly used as an ornamental plant, but like the related Thespesia populnea its wood is also valued for its durable timber.
