Anthurium marcusianum Theófilo, L.Kollmann & Sakur.

• Genus: Anthurium
• Botanical Background: Described by Theófilo, L.Kollmann, and Sakur; part of a broader group of Anthurium species discovered and described in the early 21st century.

• Geographical Range: Endemic to cloud forests in the highland regions of South America, particularly in areas with high humidity and temperatures.
• Environment: Moist, shaded environments with rich, well-draining soils, often growing in the understory of tropical forests at elevations where the air is cooler and more humid; prefers temperatures ranging between 18–25°C (64–77°F) and high humidity levels.

Leaves

• Large, glossy, and dark green
• Leathery texture
• Ovate to heart-shaped

Inflorescence (Spadix & Spathe)

• Spadix is cream-colored, with a modest size
• Encased by a spathe that is typically a pale green
• Subtle scent

Growth Habit

• Epiphytic species

• Grows on other plants

• Uses a rhizomatous structure to anchor itself

Light Requirements

• Bright, indirect
• Direct sunlight can scorch the leaves

Watering & Humidity

• Consistently moist soil
• High humidity
• Regular misting or a humidity tray
• Watered thoroughly when the top of the soil feels dry

Soil & Potting Mix

• A well-draining mix, such as a combination of peat, perlite, and pine bark
• Should be potted in a container that provides adequate drainage

Temperature & Fertilizer

• Temperature range: 18–25°C (64–77°F)

• Fertilize with a balanced, water-soluble fertilizer during the growing season

Division and Stem Cuttings

• Propagated by division of the rhizomes
• Ensuring each division has roots and a portion of the stem
• Leaf cuttings may also root under optimal conditions

Seeds

• Seeds may be viable but require precise conditions for germination, including warm temperatures and high humidity

Typical Issues

• Spider mites, mealybugs, and aphids 
• Root rot

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure good air circulation
• Avoid overwatering 

• Rarity and unique appearance
• Valuable addition to any collector's garden

• Glossy leaves and compact growth habit
• Ideal for ornamental cultivation, especially in humid environments or as a potted plant indoors.

Wild Population Status

• Not listed as endangered
• Considered rare in its natural habitat due to its specialized growing conditions

Market Availability
