Illicium guajaibonense is a shrub endemic to Pinar del Rio in Western Cuba.

These shrubs have simple, green leaves with a waxy appearance due to their thick cuticles.

Unlike other Illicium species, their leaves give off a sweet, yet spicy aroma when crushed.

Their thick sepals, petals, stamens, and carpels are poorly structured: they vary in numbers and intergrade.

However, it is known that the people of Cuba have used other species of Illicium as treatments for various ailments such as gastric/intestinal problems, menstrual cramps, rheumatism, and nasal congestion.
