Few-flowered bitterwood (Picrasma pauciflora)
Picrasma pauciflora: Characteristics and Habitat
Characterized by its exceptionally sparse and delicate inflorescences, Picrasma pauciflora inhabits the tropical woodlands of South America. This wild woody plant is highly adapted to humid forest conditions, where it thrives in shaded and partially shaded environments.
The species represents a crucial component of local biodiversity, contributing to the structural complexity of the forest canopy. Its primary distribution is centered in regions with high annual rainfall.

Morphology
This tree exhibits a slender growth habit with light grey bark that shows fine fissures. The leaves are pinnately compound, consisting of several pairs of leaflets with an odd terminal leaflet.
Its flowers are small, pale yellow, and produced in very small numbers per cluster, which explains the specific epithet pauciflora. The subsequent fruit is a small, fleshy drupe that darkens as it matures.
Flowering season
Late dry season to early wet season (September-November)
Applications
Due to its relatively scarce distribution, the plant has limited direct economic uses. The wood containing natural bitter principles is sometimes studied for potential phytotherapeutic properties.
It remains primarily valued for ecological restoration projects within its native range. Planting it helps support specialized insect and bird populations in native habitats.
Interesting facts
The Latin name pauciflora translates directly to "few-flowered," highlighting its sparse blooming habit. This makes the plant difficult to identify when not in full leaf.
Like its close relatives, the bitter taste of the foliage serves as an effective deterrent against large herbivores. This allows the saplings to survive in areas with heavy grazing pressure.
