Styrax portoricensis was described in 1892 from specimens collected in 1885 from the Sierra de Naguabo and the Sierra de Yabucoa of Puerto Rico. Specimens were subsequently collected in 1935 and 1954 in the Luquillo mountains. At the time that it was listed as endangered, only one plant was known to exist in the wild. Two additional plants have been reintroduced.
S. portoricensis is an evergreen tree growing up to 10-12m tall. The upper sides of its leaves are shiny dark green. The undersides are pale green and sparsely covered with tiny scales. The white petals have silvery scales on the inside and the fruits, which are pale reddish brown, produce just one seed each. (USFWS 1995)
Distribution & Occurrence
- Puerto Rico
Occurs in a montane forest type called palo colorado. It is an evergreen forest type, described as an upland swamp, found at elevations greater than 600m. These forests are found on somewhat protected intermediate slopes and valleys, though high winds can occur at times. They do not have high plant diversity. Some of the common species in palo colorado forest are Cyrilla racemiflora (common name palo colorado for which the association is named), Calcyogonium squamulosum, and Micropholis garcinifolia.
