Introduction & Overview

Common and Scientific Names

  • Scientific Name: Anthurium doroteryense Croat
  • Common Name: Dorbaya's Anthurium

Quick Facts

  • Origin: Native to tropical South America
  • Features: Thick, glossy, heart-shaped leaves and a compact spathe-spadix structure 

Taxonomy & Classification

  • Genus: Anthurium
  • Botanical Background: Described by botanist Thomas Croat, the species has been recognized for its unusual leaf morphology and is often cited in studies examining the diversity of tropical aroids

Natural Habitat & Distribution

  • Geographical Range: Native to select regions in tropical South America.
  • Environment: Thrives under high humidity and warm, stable temperatures, typically on well-drained soils in environments with diffused light.

Morphological Characteristics

Leaves

  • Leaves are medium-sized
  • Glossy
  • Heart-shaped
  • Deep green coloration and subtly undulated edges

Inflorescence (Spadix & Spathe)

  • Narrow spathe and central spadix 
  • Minimal scent, relying on specialized insect pollinators

Growth Habit

  • Epiphyte or terrestrial plant 
  • Forming clumps with a shallow, fibrous root system rather than extensive tubers or rhizomes

Cultivation & Care

Light Requirements

  • Bright, indirect light that mimics its natural forest understory without causing leaf burn

Watering & Humidity

  • Regular watering to maintain evenly moist soil is essential, along with a consistently high humidity level, particularly during active growth
Soil & Potting Mix

  • A loose, well-draining potting mix enriched with organic matter is recommended
  • Containers should always have adequate drainage

Temperature & Fertilizer

  • Ideal growth occurs between 65°F and 80°F
  • Use a balanced, water-soluble fertilizer sparingly during the growing season

Propagation Methods

Division and Cuttings

  • Propagation is most successfully achieved through division of clumps or by taking stem cuttings during the active growing period

Seeds

  • Less common and may require a warm, humid environment to achieve satisfactory germination rates

Common Pests & Diseases

Typical Issues

  • Spider mites 

Treatment Recommendations

  • Employ insecticidal soap for pest control
  • Adjust watering practices to prevent fungal root diseases
  • Organic fungicides can be used as needed

Notable Traits & Uses

  • Notable for its distinctive leaf shape and its ability to adapt to varying humidity levels
  • An interesting study subject in tropical botany
  • Prized for its unique aesthetic and rarity, which add a special accent to curated tropical plant collections

Conservation & Availability

Wild Population Status

  • Relatively rare in the wild
  • May be vulnerable to habitat loss resulting from deforestation

Market Availability

  • Seldom seen in general commercial trade
  • Typically available only through specialist collectors and botanical exchanges
