Morphology
This species generally reaches a height of 0.5 to 1 meter. Its foliage consists of leaves measuring 5 to 14 centimeters in length and 1.5 to 5 centimeters in width, featuring acuminated to attenuated tips and bases.
The reproductive structures are arranged in raceme inflorescences that span 5 to 10 centimeters long. Key features of the floral anatomy include:
- Pubescent axes along the inflorescence structure.
- Short pedicels measuring 3 to 5 millimeters.
- Red-purple sepals about 1.7 to 2.7 millimeters in length.
- A single whorl containing 6 to 12 stamens.
- An ovary composed of 6 to 8 partially connate carpels.
Applications
Historically, members of the genus have been utilized for their rich pigment. The berries of this plant contain deep red pigments that have been used as natural dyes for textiles and writing ink.
Although it contains active chemical compounds, it is not widely cultivated for commercial applications. Its primary value remains ecological, providing food for local bird species that are immune to its toxins.
