Wittmackia froesii is a species of flowering plant in the family Bromeliaceae, native to the Atlantic Forest biome in eastern Brazil. It is primarily found in the state of Bahia.
Taxonomy and Nomenclature
The species was originally described as Aechmea froesii by the American botanist Lyman Bradford Smith in 1955. In 2017, following a comprehensive phylogenetic and morphological re-evaluation of the subfamily Bromelioideae, the species was transferred to the resurrected genus Wittmackia by Julian Aguirre-Santoro. The specific epithet froesii honors Ricardo de Lemos Fróes, a Brazilian botanist and prolific plant collector who gathered the type specimen.
Description
Wittmackia froesii is a perennial epiphytic herb. Like many members of its family, it grows in a rosette formation, where its strap-shaped leaves overlap at the base to create a central tank that collects rainwater and organic debris. The leaves are typically characterized by serrated margins with small spines.
The inflorescence is a compound panicle that rises from the center of the rosette. It features small flowers, which are often subtended by colorful bracts. While specific floral morphology varies within the genus, Wittmackia species are generally distinguished by their ovate sepals and specific pollen characteristics.
Distribution and Habitat
The species is endemic to Brazil, specifically restricted to the tropical moist forests of Bahia. It thrives in humid environments, typically growing upon trees as an epiphyte, though it may occasionally be found as a terrestrial plant in leaf litter. Its survival is closely linked to the preservation of the Atlantic Forest (Mata Atlântica), an ecosystem characterized by high biodiversity and significant habitat fragmentation.
Cultivation
While not as widely known in general horticulture as some other bromeliads, Wittmackia froesii (often still found in trade under its synonym Aechmea froesii) is cultivated by botanical gardens and bromeliad enthusiasts. It is valued for its structured foliage and the longevity of its inflorescence. It requires warm temperatures, high humidity, and filtered light to replicate its natural environment.
