Anthurium muyunense Croat

• Genus: Anthurium
• Botanical Background: Named and described by Thomas B. Croat, Anthurium muyunense takes its name from the Muyuna region of Loreto, Peru, where it was discovered during field research in the Amazon basin.

• Geographical Range: Native to lowland tropical rainforests in northeastern Peru.
• Environment: Found in warm, humid understories of primary rainforest and thrives in environments with consistent moisture, filtered light, and rich organic soils.

Leaves

• Slender
• Lanceolate to elliptic
• Smooth margins
• Glossy green surface
• Venation subtle 
• Foliage is held upright on thin petioles

Inflorescence (Spadix & Spathe)

• Narrow, pale green spathe
• Slim spadix that may appear cream or yellow
• Not fragrant
• Likely pollinated by small beetles or flies

Growth Habit

• Terrestrial or low epiphytic plant that grows from a short stem with fibrous roots
• Forms small, clumping colonies in shaded environments

Light Requirements

• Bright, indirect light
• Avoid exposure to strong direct sun

Watering & Humidity

• Needs consistent moisture and high humidity (70% or higher)
• Allow the top layer of soil to dry slightly between waterings.

Soil & Potting Mix

• Best grown in a chunky, well-aerated substrate such as orchid bark, sphagnum moss, and perlite
• Mix should retain moisture without becoming compacted

Temperature & Fertilizer

• Prefers temperatures between 22–28°C (72–82°F)
• Fertilize monthly with a diluted, balanced fertilizer during the growing season

Division

• Propagated by division of basal offsets or by stem cuttings with nodes and roots
• Maintain high humidity during propagation

Seeds

• Propagation is rare due to limited seed availability
• Should be kept moist and warm for best results

Typical Issues

• Mealybugs, spider mites, and aphids
• Overwatering or poor airflow may lead to root or stem rot

Treatment Recommendations

• Treat infestations with neem oil or insecticidal soap
• Use well-drained soil and allow proper air circulation to reduce fungal risks

• Represents the rich biodiversity of Peru’s Amazonian flora
• Narrow leaves and understated growth habit may help it blend into its natural forest environment

• Rare in cultivation, it has appeal for collectors who specialize in unusual or region-specific Anthurium species, particularly for naturalistic tropical displays

Wild Population Status

• Not evaluated by the IUCN
• Vulnerable to deforestation and agricultural expansion

Market Availability

• Extremely rare in cultivation and unlikely to be available commercially
• Found primarily in botanical research collections or through specialized conservation programs
