Xanthosoma striatipes (Kunth & C.D.Bouché) Madison

• Genus: Xanthosoma
• Botanical Background: Originally described by Kunth and Bouché and later reclassified by botanist Michael Madison, who recognized its placement in Xanthosoma based on inflorescence and vegetative morphology.

• Geographical Range: Native to parts of northern South America
• Environment: Thrives in moist, shaded understory habitats with high humidity and organically rich soils. Often found near streams or in secondary growth areas.

Leaves

• Broadly sagittate to hastate (arrowhead-shaped), with smooth, glossy green blades
• Prominent feature is the petioles, which exhibit visible vertical striping or striations

Inflorescence (Spadix & Spathe)

• Inflorescence includes a pale, tubular spathe and a cream-colored spadix, typical of the genus
• Pollination is presumed to occur via beetles or small insects

Growth Habit

• Terrestrial, clump-forming herb with tuberous roots
• Develops a moderate canopy of foliage supported by strong, upright petioles

Light Requirements

• Bright, filtered light
• Avoid direct sun, which can damage the foliage

Watering & Humidity

• Requires consistent soil moisture
• High humidity (60–80%) supports optimal growth
  
• Particularly for young plants or indoor cultivation

Soil & Potting Mix

• Prefers a rich, airy medium composed of compost, peat, and perlite or bark
• Drainage is essential to prevent tuber rot

Temperature & Fertilizer

• Ideal temperature range is 20–30°C (68–86°F)
• Apply balanced fertilizer every 4–6 weeks during the growing season

Division

• Propagated by dividing tubers during dormancy
• Replanting offsets that develop from the main clump

Seeds

• Propagation is rarely used and requires warm, humid conditions
• Patience due to slow germination rates

Typical Issues

• Mealybugs and spider mites in dry indoor conditions
• Root rot may develop with overwatering or poorly draining soil

Treatment Recommendations

• Use insecticidal soap or neem oil for pests
• Improve airflow and monitor watering to prevent fungal issues

• Name "striatipes" refers to its striped petioles, a key identification feature
• Adds strong architectural interest in tropical landscape settings

• Highly appreciated for its unique petiole markings and broad foliage
• Rare in cultivation but sought after by collectors for its ornamental qualities

Wild Population Status

• Not evaluated by the IUCN
• Not widely documented in the wild. Habitat pressure from deforestation may pose future risks

Market Availability

• Occasionally available through specialty plant nurseries or collectors
• Not commonly found in mainstream horticulture.
