Anthurium obtusilobum Schott

• Genus: Anthurium
• Botanical Background: Described by Heinrich Wilhelm Schott, a notable botanist in aroid research, the species has been studied for its unique morphological traits. Early botanical explorations in tropical America played a crucial role in its identification and classification.

• Geographical Range: Native to lowland tropical rainforests and submontane regions of Central and South America
• Environment: Thrives in humid, shaded understory environments; prefers well-drained soils enriched with organic matter and flourishes in climates with steady moisture and moderate temperatures.

Leaves

• Broadly oval with rounded, blunt lobes
• Medium to large size, featuring a smooth texture and a rich green coloration

Inflorescence (Spadix & Spathe)

• Spadix, which is modest in length, and an accompanying spathe that may exhibit soft hues of green or cream
• Although not intensely fragrant, the spathe plays an essential role in attracting natural pollinators through visual cues

Growth Habit

• Terrestrial in nature; grows from a robust rhizome
• Maintains a compact clumping form, suitable for both natural forest floors and container cultivation in a controlled environment

Light Requirements

• Bright, indirect light that mimics dappled forest shade rather than direct sunlight

Watering & Humidity

• Regular watering is essential to maintain moist soil without waterlogging
• High ambient humidity, ideally above 60%, supports its tropical nature and prevents leaf desiccation

Soil & Potting Mix

• A loose, well-aerated potting mix enriched with organic matter is ideal
• A blend incorporating peat, perlite, and orchid bark often yields the best results
• Ensure proper drainage through a container with ample drainage hole
  

Temperature & Fertilizer

• Prefers temperatures between 65°F and 80°F (18°C to 27°C)
• A balanced liquid fertilizer applied monthly during the active growing season will support its steady development

Division and Cuttings

• Most effectively achieved through division of the rhizome

Seeds

• Less common in cultivation, the seeds are viable if mature fruit is available
• They require a warm, humid environment and a sterile medium to germinate properly

Typical Issues

• Spider mites and mealybugs
• Root rot can occur if soil drainage is insufficient

Treatment Recommendations

• Regular cleaning and the application of mild insecticidal soap are effective
• Fungal or bacterial infections are managed best by ensuring improved airflow and reducing excess moisture around the roots

• Has captured the interest of botanists due to its distinctive leaf shape and understated elegance
• Occasionally features in tropical plant displays that emphasize biodiversity

• Prized for its visually appealing foliage and manageable size
• Often showcased in mixed aroid collections, where its subtle features complement more flamboyant species

Wild Population Status

• No widespread evidence of severe decline, though habitat loss in tropical forests poses an ongoing concern for many native species

Market Availability

• Considered moderately available among specialized nurseries
