  • Common Name: Does not have widely recognized common names

Quick Facts

  • Origin: Native to tropical regions of South America
  • Features: Admired for its striking foliage and captivating spathe, making it a notable specimen among aroid collectors

Taxonomy & Classification

  • Genus: Anthurium
  • Botanical Background: Described by the botanist Thomas B. Croat, a leading authority on aroid taxonomy, this species represents a more recent addition to the scientific catalog of Anthuriums, reflecting ongoing efforts to refine plant classification.

Natural Habitat & Distribution

  • Geographical Range: Native to tropical regions in South America, with records suggesting a presence in parts of Colombia and neighboring areas.
  • Environment: Thrives in the humid understories of tropical rainforests, where filtered light, consistently moist conditions, and well-draining soils support its growth.

Morphological Characteristics

Leaves

  • Medium to large
  • Featuring a glossy texture and dark green coloration
  • Often display distinctive venation patterns

Inflorescence (Spadix & Spathe)

  • Marked by a contrasting spathe, typically ranging from deep red to burgundy, alongside a central spadix
  • Scent is subtle
  • Structure is well adapted to attract specialized pollinators

Growth Habit

  • Generally terrestrial, forming clumps with a spreading habit
  • It possesses a rhizomatous root system that enhances nutrient uptake and stability

Cultivation & Care

Light Requirements

  • Prefers bright, indirect light

Watering & Humidity

  • Regular watering is essential to maintain evenly moist soil
  • High humidity is essential
  • Avoid waterlogging to prevent root rot

Soil & Potting Mix

  • A well-aerated, organic-rich mix that offers excellent drainage is ideal
  • A blend that includes peat, perlite, and orchid bark is often recommended

Temperature & Fertilizer

  • Between 65°F and 80°F
  • Balanced, diluted fertilizer applied monthly during the growing season

Propagation Methods

Division and Stem Cuttings

  • Typically done through division of the rhizomes
  • Each division should include a portion of the root system

Seeds

  • Less frequently used due to variable germination rates
  • Require a warm, humid environment to sprout effectively

        Common Pests & Diseases

        Typical Issues

        • Spider mites and mealybugs
        • Root rot can occur if overwatered

        Treatment Recommendations

        • To prevent root rot, ensure the potting mix is well-draining and avoid standing water

        Notable Traits & Uses

        • The rarity and unique structure of this species have made it a subject of interest among botanists
        • Plays a specialized role in attracting pollinators
        • Prized for its unusual leaf form and vibrant inflorescence
        • A standout choice for private collections and botanical displays

        Conservation & Availability

        Wild Population Status

        • There is limited data regarding its conservation status
        • Habitat loss in tropical rainforests is a potential concern that may affect its wild populations

        Market Availability

        • Relatively rare in the horticultural trade
