Anthurium naviculare Cath. & Nadruz

• Genus: Anthurium
• Botanical Background: Described by Cath. & Nadruz, the species name “naviculare” highlights the characteristic boat-shaped form of its leaves; its description contributed to a deeper understanding of Anthurium diversity and the evolution of leaf morphology in tropical aroids.

• Geographical Range: Native to the moist, tropical regions of Brazil, where it occurs naturally in forested ecosystems.
• Environment: Warm, humid conditions with consistent moisture and filtered light; it favors well-drained, organic-rich soils typical of the shaded understory in tropical rainforests.

Leaves

• Boat-shaped
• Glossy finish and prominent venation
• Distinct curvature
• Smooth texture

Inflorescence (Spadix & Spathe)

• Modest spathe that partially encloses a central spadix
• Scent is minimal

Growth Habit

• Growing terrestrially
• Develops from a rhizomatous system that forms clumps
• Moderate growth habit

Light Requirements

• Bright, indirect
• Direct sunlight should be avoided to prevent leaf burn

Watering & Humidity

• Consistent moisture
• Regular watering
• Soil evenly damp but not waterlogged
• High ambient humidity

Soil & Potting Mix

• A well-draining, organically enriched mix—comprising peat, perlite, and orchid bark

Temperature & Fertilizer

• Temperatures between 18–27°C (65–80°F)

• During the active growing season, feed monthly with a balanced, water-soluble fertilizer at half strength

Division and Stem Cuttings

• Most common propagation technique is rhizome division
• Produces offspring that retain the parent plant’s desirable traits

Seeds

• Less common among cultivators due to the ease and higher success rate of vegetative propagation

Typical Issues

• Spider mites and mealybugs
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Appropriate fungicides
• Adjustments in watering practices

• Alludes to the boat-like shape of the leaves
• Contributes to ongoing studies of pollination mechanisms in tropical aroids

• Unusual leaf morphology and adaptability
• Rarity in cultivation enhances its appeal among enthusiasts seeking unique and collectible specimens

Wild Population Status

• Comprehensive assessments are limited
• Habitat loss in Brazil’s tropical forests raises concerns about the long-term viability of wild populations

Market Availability

• Relatively rare in the horticultural trade
• Sought after by dedicated collectors
• Limited availability
