Description

• Odontonema glaberrimum is a flowering shrub in the acanthus family (Acanthaceae). It has upright, branching stems and smooth, glossy, green leaves arranged in opposite pairs. Its tubular flowers grow in upright or branched clusters, with colours typically ranging from red to reddish-orange in the genus Odontonema. The flowers attract hummingbirds and other nectar-feeding visitors. Species-specific information on its distinguishing features is limited, so identification should be supported by details such as the flower structure, leaf shape, and inflorescence.

Range

• The genus Odontonema is native to tropical America, particularly Central America and parts of Mexico. Odontonema glaberrimum is represented in Zihuatanejo, Guerrero, and the surrounding area.

Habitat

• Species of Odontonema typically grow in warm, tropical environments, including forest margins, woodland understories, and shaded or partly shaded garden settings. They generally favour moist, well-drained soils and protection from intense, prolonged drought. Ornamental species are also cultivated in tropical gardens, where their colourful flower clusters attract pollinators.
