Taxonomy
- Kingdom: Plantae
- Clade: Angiosperms

- Order: Myrtales
- Family: Melastomataceae
- Genus: Tibouchina
- Species: Tibouchina sipapoana
The species belongs to the genus Tibouchina, a group of neotropical flowering plants commonly known as “glory bushes.” The specific epithet sipapoana is derived from the Sipapo River region in the Amazonas state of Venezuela, indicating the geographic area where the taxon was first collected or is primarily distributed.
Distribution
- Tibouchina sipapoana is recorded from the Venezuelan Guayana Shield, particularly in the vicinity of the Sipapo River and surrounding lowland rainforest habitats. Herbarium specimens and botanical surveys list the species as endemic to this region.
Habitat
The species occurs in tropical moist evergreen forests, often on sandy or rocky substrates associated with riverine environments. It is typically found at low to moderate elevations (approximately 100–500 m above sea level).
Morphology
Detailed morphological descriptions for T. sipapoana are limited in the publicly accessible literature. As a member of Tibouchina, it can be expected to exhibit characteristics typical of the genus, such as opposite, simple leaves with prominent venation, and inflorescences bearing five‑petaled flowers. Specific information on leaf size, flower color, fruit type, and growth habit for this species has not been comprehensively documented in readily available sources.
Conservation Status
No formal assessment of Tibouchina sipapoana has been published by the International Union for Conservation of Nature (IUCN). Its restricted distribution suggests that habitat disturbance could potentially impact the species, but the lack of population data precludes a definitive conservation rating.
Etymology
The epithet sipapoana is a toponym referring to the Sipapo River region, a common practice in botanical nomenclature to denote the locality of the type collection.
