Botanical Identification
Ecology
The ecology of Brunfelsia uniflora is characterized by its preference for specific montane environments, primarily flourishing within the Cerrado habitat. This species occupies a distinct vertical niche in the landscape, maintaining an elevational range that begins at 1500 m AMSL and extends up to a maximum of 2600 m AMSL. Within these high-altitude ecosystems, the plant's distribution is closely tied to the unique soil compositions and climatic patterns inherent to the Cerrado biome.
- Elevational range max:
- 2600 m AMSL
- Elevational range min:
- 1500 m AMSL
- Habitat :
- Cerrado
Life history
The life history of Brunfelsia uniflora is characterized by its nature as a perennial plant, allowing it to persist through multiple growing seasons. It maintains a consistent vegetative presence as an evergreen species, retaining its foliage year-round rather than shedding leaves seasonally.
- Deciduousness :
- evergreen
- Lifecycle :
- perennial
Morphology
The morphology of Brunfelsia uniflora is characterized by a woody growth form, primarily manifesting as a self-supporting shrub. This terrestrial plant reaches an average height of approximately 2.5 m and grows independently, functioning as a non-parasitic organism. It does not exhibit epiphytic tendencies, maintaining a strictly terrestrial existence rather than growing on other plants.

- Growth form :
- shrub
- Parasite :
- independent
- Plant height mean:
- 2.5 m
- Woodiness :

Physiology
The physiology of Brunfelsia uniflora is characterized by its complex metabolic processes and specific nutrient acquisition strategies. As a woody evergreen shrub, its physiological framework relies on efficient photosynthetic pathways to support its perennial growth and the production of secondary metabolites, including alkaloids and iridoids, which are central to its medicinal properties. Regarding its relationship with soil nutrients, the plant does not exhibit the physiological mechanisms required for symbiotic nitrogen fixation; therefore, it is not a nitrogen fixer. This lack of nitrogen-fixing capability means that its nitrogen requirements must be met entirely through the uptake of nitrates and ammonium ions from the rhizosphere via its root system. Its metabolic activities are highly dependent on soil moisture and organic matter availability to facilitate the transpiration stream and the translocation of nutrients throughout its vascular tissues.
- Nitrogen fixer :
- no
Reproduction
The reproduction of Brunfelsia uniflora is driven by a biotic pollination syndrome, relying on living organisms to facilitate the transfer of pollen. This reproductive process is primarily mediated by insect pollination, specifically involving various insect vectors that visit the flowers to collect nectar or pollen. The plant exhibits a specialized interaction with different insect groups, including bees, butterflies, and moths, which serve as the key agents in its pollination cycle. By utilizing these biotic mechanisms rather than abiotic factors like wind or water, the plant ensures a targeted and efficient movement of genetic material between individual flowers, supporting its successful reproductive cycle.
