Taxonomy
- Kingdom: Plantae
- Clade: Tracheophytes
- Clade: Angiosperms
- Clade: Monocots
- Order: Poales
- Family: Bromeliaceae
- Subfamily: Pitcairnioideae
- Genus: Dyckia
- Species: Dyckia hatschbachii L.B.Sm.
Authority
The species was formally described by the botanist Lyman B. Smith (abbreviated L.B.Sm.), who specialized in the Bromeliaceae family.
Etymology
The specific epithet hatschbachii honors the Brazilian botanist and field collector Gerd Hatschbach, who contributed numerous specimens from the southern and central regions of Brazil.
Distribution and Habitat
Dyckia hatschbachii is endemic to Brazil. Verified herbarium records place the species primarily in the state of Mato Grosso do Sul, where it occurs on rocky outcrops and in seasonally dry cerrado grasslands. The plant is adapted to xeric conditions and typically grows on well‑drained, sandy to lateritic soils.
Morphological Description
- Growth form: A terrestrial, rosette‑forming bromeliad that forms dense clumps.
- Leaves: Rigid, linear‑lanceolate leaves with pronounced marginal spines; leaf surfaces are often stiff and may have a gray‑green to bluish hue.
- Inflorescence: A central, erect spike bearing numerous small, terminal flowers.
- Flowers: Typically white to pale yellow, with a tubular corolla; stamens are exserted.
- Fruit: A dry, capsular fruit containing numerous minute seeds equipped with a pappus-like structure for wind dispersal.
Ecology
The species is adapted to periodic fire and drought, common in the cerrado biome. Its spiny leaves deter herbivory, and the deep-rooting habit assists in water acquisition from shallow substrates. Pollination is presumed to involve insects such as bees, though specific pollinator observations are lacking.
Conservation Status
As of the latest assessments, Dyckia hatschbachii has not been evaluated by the International Union for Conservation of Nature (IUCN). However, habitat conversion associated with agriculture and mining in the Mato Grosso do Sul region may pose localized threats.
Cultivation
The species is occasionally cultivated in botanical gardens and by bromeliad enthusiasts for its ornamental foliage and tolerance of arid conditions. Successful cultivation requires a well‑draining substrate, full sun to partial shade, and minimal watering during dormant periods.
