Xanthosoma saguasense G.S.Bunting

• Genus: Xanthosoma
• Botanical Background: Named and described by American botanist George S. Bunting, a specialist in the flora of Venezuela, where this species was first collected and documented.

• Geographical Range: Native to Venezuela
• Environment: Found in lowland tropical forests and moist, shaded habitats with rich, well-drained soils. It thrives in warm, humid conditions with consistent rainfall.

Leaves

• Broad, sagittate leaves with smooth texture and a uniform green color
• Leaf blades are large and supported by stout, upright petioles

Inflorescence (Spadix & Spathe)

• Pale yellow or greenish spathe that partially encloses the spadix
• Inflorescence is presumed to follow typical Xanthosoma pollination patterns, often involving beetles

Growth Habit

• Terrestrial, tuberous species forming upright clumps
• Anchors itself in the soil with thick underground storage organs and does not exhibit climbing or epiphytic behavior

Light Requirements

• Grows best in bright, filtered light or partial shade
• Avoid exposure to intense, direct sun for extended periods

Watering & Humidity

• Requires evenly moist soil and high humidity to thrive
• Do not allow the soil to completely dry out during the growing season

Soil & Potting Mix

• Use a fertile, well-draining potting mix enriched with compost or organic matter
• Ensure good drainage to prevent root rot

Temperature & Fertilizer

• Ideal temperature range is 22–30°C (72–86°F)
• Apply a balanced fertilizer every 3–4 weeks during active growth

Division

• Propagated primarily by dividing its underground tubers
• Section should include at least one growing bud

Seeds

• Propagation is rarely practiced
• Lacks detailed documentation for this species

Typical Issues

• Spider mites, aphids, and root rot
• Monitor humidity and soil moisture to avoid infestations and fungal problems

Treatment Recommendations

• Use neem oil or insecticidal soap for pests
• Avoid overwatering and ensure proper airflow around the plant to reduce disease risks

• Name refers to the Sagua region of Venezuela
• Narrow geographic origin and potential endemism

• Rare in cultivation, the plant’s large leaves and tropical presence offer appeal to collectors
• Aroid specialists seeking unusual Xanthosoma species

Wild Population Status

• Conservation status is not formally assessed
• Restricted distribution may make it vulnerable to habitat disturbance or deforestation

Market Availability

• Extremely rare in horticulture
• Not commonly offered by commercial nurseries and is mainly found in scientific or botanical collections
