Pohl's Homalolepis (Homalolepis pohliana)
Homalolepis pohliana: Species Profile and Habitat Information
Inhabiting the fire-prone savanna ecosystems of the Brazilian Cerrado, Homalolepis pohliana displays exceptional resilience and specialized growth habits. This woody species has evolved to withstand both seasonal droughts and regular wildfire cycles characteristic of its native habitat.
Named in honor of the Austrian botanist Johann Emanuel Pohl, it remains an important component of the regional flora. Modern researchers study this plant to better understand the evolutionary adaptations of the genus in South American biomes.

Morphology
This woody plant typically forms a multi-stemmed shrub or a compact small tree. The bark of Homalolepis pohliana is relatively thick and corky, providing essential protection against heat and environmental stressors.
Its leaves are arranged in an alternate pattern and are compound, usually consisting of three to five leaflets. These leaflets are elliptic or lanceolate, possessing a smooth margin and a slightly coriaceous texture to resist dehydration.
The inflorescences are structured as terminal panicles, bearing small, pale green or yellowish flowers. Each flower contains five petals and small stamens, designed for insect pollination. The fruit develops as a small, rounded drupe containing one hard seed.
Applications
Its ecological value represents the primary significance of this species in its native environment. Homalolepis pohliana contributes to the biodiverse plant communities of the Cerrado, providing food and shelter for specialized savanna wildlife.
Its tough, fibrous wood is sometimes used locally for fuel and small crafts. Furthermore, its ability to survive in nutrient-poor soils makes it a subject of interest for ecological restoration programs in savanna landscapes.
Interesting facts
The naming of this species commemorates Johann Emanuel Pohl, who collected extensively in Brazil during the early nineteenth century. This plant's survival strategy is heavily reliant on its deep root system, which accesses water reserves far below the surface during dry periods.
Key facts regarding this species include:
- Fire adaptation: The thick bark helps protect the inner vascular tissue from the intense heat of savanna fires.
- Nectar source: Its inconspicuous flowers bloom when many other plants are dormant, offering critical nectar to insects.
- Taxonomic relocation: Previously placed under the genus Simaba, it was reassigned to Homalolepis following modern genetic studies.
