- Genus: Vriesea
- Species: Vriesea maxoniana L.B.Sm.
The species was formally described by botanist Lyman B. Smith. The specific epithet “maxoniana” honors the American botanist William Ralph Maxon (1875–1948), noted for his work on ferns and tropical plants.
Description
Vriesea maxoniana is an epiphytic bromeliad characterized by a rosette of stiff, narrowly lanceolate leaves that are typically dark green with a subtle bronzy sheen. The leaf margins may possess fine serrations. The inflorescence emerges from the center of the rosette, bearing a paniculate arrangement of brightly colored bracts—commonly shades of orange to reddish‑purple—surrounding small, tubular flowers. The flowers themselves are generally white to pale pink, with recurved sepals and petals adapted for pollination by hummingbirds. As with many Vriesea species, the plant forms a water‑holding central tank that collects rainwater and organic debris.
Distribution and Habitat
- Geographic range: Endemic to Brazil.
- Typical habitats: Atlantic Forest (Mata Atlântica) moist, subtropical to tropical forest zones, often growing as an epiphyte on tree trunks and branches at elevations from sea level to roughly 1,200 m.
Precise locality records are limited; herbarium specimens have been documented from the states of Espírito São Pedro e Goiás and Rio de Janeiro.
Ecology
The tank habit of V. maxoniana supports a micro‑ecosystem of insects, amphibian larvae, and microorganisms, contributing to nutrient acquisition. Flower morphology suggests ornithophily (bird pollination), particularly by hummingbirds, which are common pollinators of many Vriesea species.
Cultivation
Vriesea maxoniana is cultivated by bromeliad enthusiasts for its ornamental foliage and vivid inflorescence. Cultivation requirements include:
- Light: Bright, indirect light; some direct morning sun is tolerated.
- Temperature: Minimum 10 °C (50 °F); optimal range 18–26 °C (65–80 °F).
- Watering: Regular watering of the central tank, ensuring it remains filled but not stagnant; excess water should be allowed to drain.
- Substrate: Grown mounted on cork bark, wood slabs, or in a well‑draining epiphytic mix (e.g., orchid bark, perlite).
- Humidity: High relative humidity (≥60 %) promotes healthy growth.
Propagation is generally achieved by seed or by separating offsets (pups) that develop after flowering.
Conservation Status
The conservation assessment for Vriesea maxoniana has not been formally evaluated by the International Union for Conservation of Nature (IUCN). However, habitat loss within the Atlantic Forest biome is extensive, and many endemic bromeliads are subject to pressure from deforestation and illegal collection. Consequently, the species may be considered at risk, though specific population data are lacking.
